SM2T3V3A Low voltage Transil™ Datasheet - production data Description The SM2T3V3A is a Transil diode designed specifically for portable equipment and K miniaturized electronic devices subject to ESD transient overvoltages. It's low stand-off voltage makes it suitable for low voltage applications very sensitive to EOS and ESD events. A Transil diodes provide high overvoltage protection DO-216AA by clamping action. (STmite) Features • Unidirectional Transil diode • High peak pulse power: 200 W (10/1000 µs) • Stand-off voltage 3.3 V • Low clamping factor V /V CL BR • Fast response time • JEDEC registered package outline TM: Transil is a trademark of STMicroelectronics August 2015 DocID11738 Rev 3 1/6 This is information on a product in full production. www.st.com
