Product details
Overview
SMCJ60AHM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount 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 voltage (VBR) at 1 mA, 96.8 V maximum clamping voltage (VC) at 15.5 A peak pulse current (IPPM), and 1500 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive ECUs, industrial motor drives, and telecom power supplies.
For engineers reviewing the SMCJ60AHM3_A/I datasheet, SMCJ60AHM3_A/I pinout, SMCJ60AHM3_A/I application, or SMCJ60AHM3_A/I equivalent, key selection criteria include clamping performance under 1500 W surge, AEC-Q101 qualification status, halogen-free RoHS compliance, thermal resistance (RθJA = 75 °C/W), and compatibility with automated SMT assembly on 8 mm × 8 mm copper pads.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, triggered when reverse voltage exceeds VBR (66.7–73.7 V), limiting transient energy to safe levels via low incremental surge resistance. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), while the SMC package supports high surge current handling without thermal runaway.
The device is rated for continuous operation from −55 °C to +150 °C junction temperature, with 1.0 µA max reverse leakage at 60 V and 200 A non-repetitive forward surge capability (8.3 ms half-sine). It meets JESD201 Class 2 whisker resistance and MSL Level 1 per J-STD-020 (peak reflow 260 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin for 48 V systems. |
| VBR @ IT = 1 mA | 66.7–73.7 V - Measured breakdown range confirming reliable turn-on threshold across production lot. |
| VC @ IPPM = 15.5 A | 96.8 V - Clamped voltage during 10/1000 µs surge; determines maximum stress imposed on protected ICs. |
| PPPM | 1500 W - Peak pulse power dissipation capacity; enables protection against IEC 61000-4-5 Level 4 surges. |
| IFSM | 200 A - Single half-sine surge rating (8.3 ms); validates survivability against inductive switch-off events. |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance on standard PCB pad; informs derating above 25 °C ambient. |
| Package | SMC (DO-214AB) - Surface-mount outline with 8.0 mm × 8.0 mm thermal pad footprint; compatible with IPC-7351B. |
Pinout & Package
SMCJ60AHM3_A/I uses the standard SMC (DO-214AB) package: cathode-indicated by a band on one end; anode at opposite end. Leads are matte tin-plated, solderable per J-STD-002 and JESD22-B102, with polarity critical for unidirectional operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected line; conducts surge current to ground when VREV > VBR. |
| Anode (unmarked end) | Reference node | Typically tied to system ground or lower-potential rail; completes clamping path during overvoltage event. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC specification. |
| Halogen-free & RoHS-compliant | Meets EU RoHS Directive 2011/65/EU and IEC 61249-2-21; no brominated flame retardants in molding compound. |
| Low incremental surge resistance | Enables tighter clamping (VC − VBR ≈ 29 V) and higher energy absorption efficiency vs. higher-RSURGE alternatives. |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and reflow at 260 °C peak without baking; simplifies manufacturing logistics. |
| Glass passivated junction | Provides stable VBR tolerance and long-term parameter stability under thermal and electrical stress. |
Applications
| Automotive Power Rail Protection | Industrial Motor Drive Control |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ60AHE3_A/I | Lower PPPM (400 W), smaller SMA package (DO-214AC), same VWM/VBR range but higher VC (103 V @ 3.5 A). | Suitable for space-constrained consumer electronics with lower surge exposure; not rated for automotive or industrial 1500 W events. | Select when board area is critical and surge threat level is ≤IEC 61000-4-5 Level 2. |
| SMCJ60AHE3_A/I | Identical electrical specs and SMC package, but RoHS-compliant without halogen-free certification (base suffix E3 vs HM3). | Acceptable for commercial/industrial use where halogen-free compliance is not mandated by OEM or regional regulation. | Choose for cost-sensitive designs where halogen-free material is not required by procurement policy. |
Compared with SMCJ60AHM3_A/I, SMAJ60AHE3_A/I offers reduced surge capacity and footprint at lower cost, while SMCJ60AHE3_A/I matches all performance metrics except halogen-free status - making it viable where environmental compliance is less stringent.

FAQ
What is the clamping voltage of SMCJ60AHM3_A/I at its rated peak pulse current?
The SMCJ60AHM3_A/I has a maximum clamping voltage (VC) of 96.8 V when subjected to its rated 10/1000 µs peak pulse current of 15.5 A. This value is measured under standardized test conditions per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during surge events. The SMCJ60AHM3_A/I maintains this clamping performance across its full operating temperature range.
Is SMCJ60AHM3_A/I qualified for automotive applications?
Yes, SMCJ60AHM3_A/I is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HM3" and documentation in the SMCJ5.0A–SMCJ188CA datasheet (Rev. 09-Jan-2024, Doc. #88394). This qualification covers stress tests including HTGB, H3TRB, temperature cycling, and ESD, validating its suitability for under-hood and chassis-mounted automotive electronics.
How does the halogen-free designation affect SMCJ60AHM3_A/I's material composition?
The "HM3" suffix in SMCJ60AHM3_A/I indicates halogen-free construction per IEC 61249-2-21, meaning the epoxy molding compound contains no brominated or chlorinated flame retardants. This reduces toxic gas emission during PCB rework or fire scenarios and aligns with strict environmental requirements in EU and Asian automotive supply chains - without compromising electrical or thermal performance versus standard E3 variants.
What is the thermal resistance of SMCJ60AHM3_A/I, and how does it impact layout design?
The SMCJ60AHM3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. This value requires PCB designers to allocate sufficient copper area and consider airflow or adjacent heat sources when operating near maximum power dissipation (6.5 W at 50 °C ambient). Derating curves in Figure 2 must be applied for ambient temperatures above 25 °C.
Can SMCJ60AHM3_A/I be used in bidirectional configurations?
No, SMCJ60AHM3_A/I is a unidirectional TVS diode, indicated by the "A" (not "CA") suffix and presence of a cathode band. Bidirectional operation requires the "CA" variant (e.g., SMCJ60CA), which lacks polarity marking and exhibits symmetric clamping in both directions. Using SMCJ60AHM3_A/I in reverse-biased AC applications would result in forward conduction and potential failure.
