The SMLJ45A is a Transient Voltage Suppressor Diode designed for surge and ESD protection in portable communications, computing, and video equipment applications. It features a compact surface mount SMC (DO-214AB) package with a standoff voltage of 45 volts and a peak pulse power dissipation rating of 3000 watts at 1 ms pulse duration. The device offers fast response times of less than 5.0 nanoseconds for bidirectional operation and operates reliably across a temperature range of -55°C to +150°C. With a peak forward surge current capability of 300 amps and steady-state power dissipation of 5.0 watts at 75°C, the SMLJ45A provides robust protection for sensitive electronic circuits. Its RoHS-compliant design and flat configuration minimize component roll-away during assembly, making it ideal for automated pick-and-place manufacturing processes.
