Volume shipments start today. This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20260317428805/en/ Demand is growing for automotive equipment relay units with a longer life, a trend that has led to increased use of SSR instead of mechanical relays. As automotive systems continue to evolve, the shift to SSR is expected to accelerate further. TLX9920 is suitable for use as a gate driver for the high-voltage power MOSFET used in SSR. Combined with a high-voltage power MOSFET, it can achieve high-voltage and high-current switching that is difficult with photorelays. As SSR have no physical contacts, unlike mechanical relays, contact wear and the need for regular maintenance are eliminated. TLX9920 also complies with AEC-Q101, the automotive electronic component reliability standard. It is housed in an SO6L package with a creepage distance of over 8mm, which realizes high isolation voltage (BVs=5000Vrms). For example, the IEC 60664-12\[2\] international standard requires a creepage distance of 5.6mm or more for application in environments with pollution degree 2 and an operating voltage of 400V or more. TLX9920 meets this requirement. TLX9920 is suitable for application in high-voltage systems and harsh environmental conditions. It can be used in a wide range of switching applications in automotive equipment, energy storage systems (ESS) and industrial power equipment. Toshiba will continue to contribute to building a safe and sustainable society by developing products for automotive and industrial equipment that enhance reliability and advance technological innovation. Notes: \[1\] Semiconductor relays that are used to control high-power loads (heating elements, motors) with low-voltage signals. The primary (control) side and the secondary (switching) side are electrically isolated by an isolation barrier, which allows switching of circuits directly connected to AC lines, or switching between devices with different ground potentials. \[2\] The standard that specifies principles, requirements, and test methods for insulation coordination for systems up to AC 1000V or DC 1500V. **Applications** - Automotive equipment: Battery management systems (BMS), onboard chargers, inverters, etc. - Industrial equipment: Energy storage systems (ESS) **Features** - Thin and long creepage package: SO6L (3.84×10.0×2.1 (mm)) - Long creepage distance: 8mm (min) - High isolation voltage: BVS＝5000Vrms (min) - Open voltage: VOC＝13.5V (min) - Short-circuit current: ISC＝8μA (min) - AEC-Q101 qualified **Main Specifications** (Unless otherwise specified, Ta\=25℃) Part Number TLX9920 Discharge circuit Integrated Absolute maximum ratings Operating temperature Topr (°C) \-40 to 125 Electrical characteristics Input forward voltage VF (V) IF\=10mA Min 1.5 Typ. 1.65 Max 1.8 Coupled electrical characteristics Open voltage VOC (V) IF\=10mA Min 13.5 Short-circuit current ISC (μA) IF\=10mA Min 8 Trigger LED current IFT (mA) Max 3 Switching characteristics Turn-on time ton (ms) Typ. 0.6 Max 1.0 Turn-off time toff (ms) Typ. 0.1 Max 1.0 Isolation characteristics Isolation voltage BVS (Vrms) Min 5000 Clearance distance (mm) Min 8 Creepage distance (mm) Min 8 Package Name SO6L Size (mm) Typ. 3.84×10.0×2.1 Sample Check & Availability Buy Online Follow the link below for more on the new product.
