1.5SMCJ5.0A – MULTICOMP

Overview

The MULTICOMP 1.5SMCJ5.0A is a robust 1500W Transient Voltage Suppressor (TVS) diode designed for critical circuit protection applications. Its primary function is to clamp transient voltage surges to a safe level, safeguarding sensitive downstream components from damage. A key design consideration for such devices is the trade-off between clamping voltage and peak pulse current handling; while this unit excels at dissipating 163A (10/1000µs) at a 9.2V clamp, designers must carefully account for its internal impedance when specifying protection levels for extremely fast rise-time transients where the effective clamp voltage might slightly exceed the nominal 9.2V.
