Product details
Overview
SMA5J16CAHE3_A/I from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for high-energy surge protection on signal and power lines. It features a 16 V stand-off voltage (VWM), 17.8–19.7 V breakdown voltage (VBR), 500 W peak pulse power (10/1000 μs), clamping voltage of 26.0 V at 19.2 A IPPM, and AEC-Q101 qualification for automotive applications.
For engineers reviewing the SMA5J16CAHE3_A/I datasheet, SMA5J16CAHE3_A/I pinout, SMA5J16CAHE3_A/I application, or SMA5J16CAHE3_A/I equivalent, key selection criteria include bidirectional clamping capability, low clamping ratio (VC/VWM ≈ 1.63), MSL Level 1 moisture sensitivity, and RoHS-compliant matte tin terminals suitable for automated SMT assembly.
Technical Context
This device operates as a voltage-clamped crowbar during transients, leveraging an avalanche junction to limit reverse voltage across protected circuits. Its bidirectional symmetry ensures identical clamping behavior in both polarities, with no polarity marking required on the SMA package.
Designed for 10/1000 μs surge waveforms per IEC 61000-4-5, it delivers 19.2 A peak pulse current (IPPM) while maintaining ≤26.0 V clamping, and exhibits low incremental surge resistance for minimal voltage overshoot under fast-rising transients.

FAQ
What is the polarity configuration of SMA5J16CAHE3_A/I?
The SMA5J16CAHE3_A/I is a bidirectional TVS diode with symmetrical anode/cathode terminals - neither end is marked, and clamping occurs identically for positive or negative transients. This eliminates orientation concerns during automated placement and simplifies PCB layout for AC-coupled or differential signal lines.
Does SMA5J16CAHE3_A/I meet automotive qualification standards?
Yes, SMA5J16CAHE3_A/I is AEC-Q101 qualified, having passed stress tests including temperature cycling, high-temperature reverse bias (HTRB), and ESD per JESD22-A114. It is approved for use in automotive subsystems such as body electronics, infotainment, and ADAS sensor interfaces where reliability under thermal and electrical stress is critical.
What is the maximum clamping voltage of SMA5J16CAHE3_A/I under surge conditions?
The SMA5J16CAHE3_A/I clamps to a maximum of 26.0 V when subjected to its rated peak pulse current of 19.2 A (10/1000 μs waveform). This value is measured at the device terminals and represents the upper bound of voltage imposed on protected circuitry during standardized surge events.
How does SMA5J16CAHE3_A/I differ from unidirectional variants like SMA5J16AHE3_A/I?
Unlike the unidirectional SMA5J16AHE3_A/I, the SMA5J16CAHE3_A/I provides identical clamping in both directions and lacks a cathode band marking. It supports AC signal paths and differential buses without polarity constraints, whereas the unidirectional version requires correct orientation and only protects against reverse-polarity transients.
Is SMA5J16CAHE3_A/I compatible with lead-free reflow processes?
Yes, SMA5J16CAHE3_A/I is rated MSL Level 1 per J-STD-020 and supports peak reflow temperatures up to 260 °C. Its matte tin-plated leads are solderable per J-STD-002, and no pre-baking is required - making it fully compatible with standard lead-free SMT assembly lines.
