Product details
Overview
SMCJ60CAHM3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection. It features 60 V standoff voltage (VWM), 66.7–73.7 V breakdown voltage (VBR) at 1 mA, 1500 W peak pulse power (10/1000 µs), and clamps transients to ≤96.8 V at 15.5 A IPPM. It is halogen-free, RoHS-compliant, and AEC-Q101 qualified for automotive-grade reliability.
For engineers reviewing the SMCJ60CAHM3_A/H datasheet, SMCJ60CAHM3_A/H pinout, SMCJ60CAHM3_A/H application, or SMCJ60CAHM3_A/H equivalent, key selection criteria include bidirectional clamping capability, 1500 W surge rating, AEC-Q101 qualification, low thermal resistance (RθJL = 15 °C/W), and compatibility with automated SMT assembly on standard PCB pad layouts.
Technical Context
This TVS diode operates symmetrically in both directions, enabling robust protection of AC-coupled or differential signal lines without polarity concerns. Its glass-passivated junction ensures stable breakdown characteristics and fast response (<1 ns), while the SMC package supports high thermal dissipation under repetitive surge conditions.
The device complies with IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and ISO 7637-2 (automotive transients). Its 150 °C maximum junction temperature and MSL Level 1 rating allow reflow soldering at 260 °C peak, making it suitable for high-reliability industrial and automotive PCBs.
Key Specifications

FAQ
What does the "HM3" suffix indicate in SMCJ60CAHM3_A/H?
The HM3 suffix denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. This means SMCJ60CAHM3_A/H meets automotive reliability standards and environmental regulations, including JESD201 Class 2 whisker resistance and UL 94 V-0 flammability rating for the molding compound.
Can SMCJ60CAHM3_A/H replace unidirectional SMCJ60AHM3_A/H in a design?
No - SMCJ60CAHM3_A/H is bidirectional and lacks polarity marking, while SMCJ60AHM3_A/H is unidirectional with cathode band identification. Substituting them risks incorrect clamping behavior on DC-biased lines. Use SMCJ60CAHM3_A/H only where symmetrical surge protection is required, such as across differential pairs or AC-coupled signals.
What is the recommended PCB pad layout for SMCJ60CAHM3_A/H?
Vishay specifies 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal for optimal thermal performance and surge current handling. This layout ensures RθJL remains at 15 °C/W and supports full 1500 W PPPM rating per the datasheet's derating curve (Fig. 2).
Does SMCJ60CAHM3_A/H meet IEC 61000-4-5 surge immunity requirements?
Yes - with its 1500 W peak pulse power rating and ≤96.8 V clamping voltage, SMCJ60CAHM3_A/H can protect downstream circuitry against 1 kV/50 Ω combination wave surges (IEC 61000-4-5 Level 3), provided the PCB layout follows Vishay's recommended pad dimensions and grounding practices.
Is SMCJ60CAHM3_A/H compatible with lead-free reflow soldering?
Yes - SMCJ60CAHM3_A/H is rated for MSL Level 1 per J-STD-020 and supports peak reflow temperatures up to 260 °C. Its matte tin-plated leads comply with J-STD-002 and JESD22-B102, ensuring reliable wetting and joint integrity in Pb-free assembly processes.
