Product details
Overview
SMCJ60AHE3_A/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for robust overvoltage protection of DC power rails and signal lines. It features a 60 V standoff voltage (VWM), 66.7–73.7 V breakdown range (VBR at 1 mA), 96.8 V clamping voltage (VC) at 15.5 A peak pulse current (IPPM), and 1500 W peak pulse power (10/1000 µs waveform), commonly deployed in automotive power supply inputs and industrial sensor interfaces.
For engineers reviewing the SMCJ60AHE3_A/H datasheet, SMCJ60AHE3_A/H pinout, SMCJ60AHE3_A/H application, or SMCJ60AHE3_A/H equivalent, key selection criteria include its AEC-Q101 qualification, low incremental surge resistance, 150 °C maximum junction temperature, and compatibility with automated SMT assembly on standard PCB copper pads.
Technical Context
This TVS diode operates as a unidirectional clamping device: under normal conditions it presents high impedance above 60 V reverse bias, then rapidly transitions to low-impedance conduction when transients exceed its breakdown threshold. Its glass-passivated junction ensures stable leakage (<1 µA at VWM) and repeatable clamping performance across temperature.
The SMCJ60AHE3_A/H delivers 1500 W surge handling per IEC 61000-4-5 (10/1000 µs) with minimal voltage overshoot due to sub-nanosecond response time and low dynamic impedance. Its thermal design supports 6.5 W steady-state dissipation on infinite heatsink at 50 °C ambient, with RθJA = 75 °C/W and RθJL = 15 °C/W enabling effective PCB-level thermal management.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 66.7 V / 73.7 V at 1 mA - Confirmed breakdown range defining turn-on threshold tolerance |
| VC @ IPPM | 96.8 V at 15.5 A - Clamped voltage during 1500 W transient, limiting downstream stress |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ60A-E3/57T | Lower PPPM (400 W), same VWM/VC, SMA package (smaller thermal mass) | Limited to lower-energy transients; unsuitable for automotive load dump | Select only for space-constrained consumer applications with ≤400 W surge exposure |
| 1.5KE60A | Through-hole DO-201 package, identical electrical specs but higher RθJA (100 °C/W) | Requires wave soldering; incompatible with fully SMT production | Choose only for legacy board redesigns retaining through-hole assembly infrastructure |
Compared with SMAJ60A-E3/57T and 1.5KE60A, the SMCJ60AHE3_A/H provides superior surge robustness (1500 W vs. 400 W/1500 W) in an AEC-Q101-qualified SMC package optimized for automated SMT and automotive thermal environments.

FAQ
What is the clamping voltage of the SMCJ60AHE3_A/H under maximum rated surge current?
The SMCJ60AHE3_A/H clamps to 96.8 V when subjected to its maximum peak pulse current of 15.5 A (10/1000 µs waveform). This value is measured per standard test conditions and defines the upper voltage limit imposed on protected circuitry during worst-case transients. The clamping performance remains stable across its -55 °C to +150 °C operating junction temperature range, making SMCJ60AHE3_A/H suitable for under-hood automotive deployment.
Is the SMCJ60AHE3_A/H qualified for automotive applications?
Yes, the SMCJ60AHE3_A/H carries AEC-Q101 qualification, confirming compliance with stress tests including high-temperature reverse bias, temperature cycling, and highly accelerated life testing. Its HE3 suffix explicitly denotes RoHS-compliant and AEC-Q101-qualified construction. This makes SMCJ60AHE3_A/H appropriate for use in automotive power distribution modules, body control units, and ADAS sensor power conditioning circuits where field reliability is mandatory.
How does the SMCJ60AHE3_A/H differ from bidirectional variants like SMCJ60CA?
The SMCJ60AHE3_A/H is unidirectional, meaning it conducts only during reverse-biased overvoltage events and blocks forward current - ideal for DC power rail protection. In contrast, SMCJ60CA is bidirectional and clamps symmetrically in both polarities, suited for AC signal lines or differential buses. The SMCJ60AHE3_A/H has a cathode band marking; SMCJ60CA has no polarity marking. Electrical parameters such as VWM, VBR, and VC are specified identically in magnitude but apply only to reverse direction for SMCJ60AHE3_A/H.
What PCB layout guidance applies to the SMCJ60AHE3_A/H for optimal thermal performance?
For reliable thermal management, the SMCJ60AHE3_A/H must be mounted on minimum 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal, as specified in the Vishay datasheet. These pads act as heat sinks to sustain its 6.5 W power dissipation rating at 50 °C ambient. Avoid narrow traces between the device and ground/power planes; use multiple thermal vias under pads if internal layers are used for heat spreading. The SMCJ60AHE3_A/H's RθJL = 15 °C/W indicates lead-to-pad conduction dominates thermal path, so pad size directly impacts junction temperature rise.
Can the SMCJ60AHE3_A/H replace older SMCJ60A variants without design changes?
Yes, the SMCJ60AHE3_A/H maintains identical electrical specifications, mechanical dimensions, and pinout as legacy SMCJ60A parts - including VWM = 60 V, VC = 96.8 V, and SMC (DO-214AB) package. The HE3 suffix adds AEC-Q101 qualification and RoHS compliance but does not alter footprint or functionality. Therefore, SMCJ60AHE3_A/H can be drop-in substituted in existing designs targeting enhanced automotive reliability or updated environmental compliance, with no PCB or schematic modifications required.
