Product details
Overview
SMCJ60AHM3_A/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection. It features a 60 V stand-off 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 (PPPM) with 10/1000 µs waveform - deployed to safeguard MOSFETs, ICs, and sensor signal lines against inductive switching transients in automotive and industrial power supplies.
For engineers reviewing the SMCJ60AHM3_A/H datasheet, SMCJ60AHM3_A/H pinout, SMCJ60AHM3_A/H application, or SMCJ60AHM3_A/H equivalent, this part delivers AEC-Q101 qualification, halogen-free RoHS compliance, MSL Level 1 moisture sensitivity, and verified clamping performance under standardized surge waveforms - critical for ESD and lightning-induced transient suppression in DC bus and interface line protection.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, optimized for fast response (<1 ns) and low incremental surge resistance. Its glass-passivated junction ensures stable breakdown characteristics across -55 °C to +150 °C operating temperature range, and its thermal resistance (RθJA = 75 °C/W) supports reliable operation on standard 8.0 mm × 8.0 mm copper pads.
The SMCJ60AHM3_A/H is rated for 200 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine) and exhibits 0.105 %/°C temperature coefficient of VBR - enabling predictable voltage clamping behavior over wide ambient conditions in automotive-grade power rail protection.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ60AHE3/A | Lower PPPM (400 W), SMA package (smaller footprint, higher RθJA) | Suitable only for lower-energy transients; not recommended for automotive load-dump | Select when board space is constrained and surge energy is limited to <500 W |
| SMCJ60AHE3_A/H | Same electrical specs but commercial-grade (non-AEC-Q101), E3 suffix (RoHS, not halogen-free) | Lacks automotive qualification; acceptable for industrial/commercial power supplies | Choose for cost-sensitive non-automotive designs where halogen-free is not mandated |
Compared with SMCJ60AHM3_A/H, SMAJ60AHE3/A offers reduced surge capacity in a smaller package, while SMCJ60AHE3_A/H provides identical clamping performance without AEC-Q101 or halogen-free assurance - making the HM3 variant uniquely suited for Tier-1 automotive sourcing requirements.

FAQ
What is the clamping voltage of SMCJ60AHM3_A/H at its rated peak pulse current?
The SMCJ60AHM3_A/H has a maximum clamping voltage (VC) of 96.8 V at 15.5 A peak pulse current (IPPM) under a 10/1000 µs waveform. This value is measured per standard test conditions and defines the upper voltage limit imposed on protected circuits during surge events - a critical parameter for ensuring downstream ICs remain within absolute maximum ratings. The SMCJ60AHM3_A/H achieves this with low incremental surge resistance and stable junction characteristics.
Is SMCJ60AHM3_A/H qualified for automotive applications?
Yes, SMCJ60AHM3_A/H is AEC-Q101 qualified, as confirmed by Vishay's ordering code structure (HM3 suffix with "H" revision and automotive-grade marking). It meets the stress test requirements for temperature cycling, humidity bias, mechanical shock, and surge immunity required for under-hood and chassis-mounted electronics. This qualification is explicitly documented in Vishay's datasheet revision 09-Jan-2024, making SMCJ60AHM3_A/H suitable for engine control, ADAS, and body electronics systems.
What does the "HM3" suffix indicate in SMCJ60AHM3_A/H?
The "HM3" suffix in SMCJ60AHM3_A/H denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. "H" indicates the automotive-grade revision level, "M3" specifies halogen-free molding compound and plating, and "_A/H" refers to the tape-and-reel packaging format (7-inch reel, 850 units). This distinguishes it from commercial variants like E3 (RoHS only) or HE3 (AEC-Q101 but not halogen-free), confirming full environmental and automotive compliance for SMCJ60AHM3_A/H.
How does SMCJ60AHM3_A/H compare to bidirectional versions like SMCJ60CA?
SMCJ60AHM3_A/H is unidirectional and features a cathode band for polarity-sensitive placement, whereas SMCJ60CA is bidirectional with no polarity marking and symmetrical clamping in both directions. Electrically, SMCJ60AHM3_A/H has VWM = 60 V and VBR = 66.7–73.7 V, while SMCJ60CA shares identical VWM and VBR ranges but supports AC-coupled or floating-line protection. SMCJ60AHM3_A/H is preferred for DC power rail protection where polarity is fixed and higher surge margin is needed.
What is the thermal resistance of SMCJ60AHM3_A/H, and how does it affect layout?
The SMCJ60AHM3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 8.0 mm × 8.0 mm copper pads per terminal. This value assumes minimum recommended pad layout per Vishay's datasheet - underscoring the need for adequate copper area to maintain TJ ≤ 150 °C during repetitive surge events. Layouts with reduced pad size or no thermal vias will increase RθJA, potentially derating surge capability and requiring verification via thermal simulation or testing for SMCJ60AHM3_A/H.
