Product details
Overview
SMCJ60AHM3/H 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 clamping voltage (VC) at 15.5 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM) with 10/1000 µs waveform - used to safeguard MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the SMCJ60AHM3/H datasheet, SMCJ60AHM3/H pinout, SMCJ60AHM3/H application, or SMCJ60AHM3/H equivalent, key selection criteria include clamping performance under 1500 W surge, AEC-Q101 qualification status, halogen-free RoHS compliance (HM3 suffix), thermal resistance (RθJA = 75 °C/W), and unidirectional polarity marking for correct PCB orientation.
Technical Context
This TVS diode operates as a fast-acting shunt protector that clamps transient overvoltages above its breakdown threshold while maintaining low leakage (<1.0 µA at 60 V). Its glass-passivated junction ensures stable VBR tolerance and long-term reliability under repetitive surge stress.
The device is rated for -55 °C to +150 °C operating junction temperature, supports 200 A non-repetitive forward surge current (IFSM), and meets J-STD-020 MSL Level 1 with 260 °C reflow peak - confirming suitability for high-volume automated SMT assembly without moisture sensitivity concerns.
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 - defines precise conduction onset window for predictable protection threshold |
| VC @ IPPM | 96.8 V at 15.5 A - clamped voltage during full 1500 W surge, limiting stress on downstream components |
| PPPM | 1500 W - peak transient energy absorption capability with standard 10/1000 µs waveform |
| RθJA | 75 °C/W - thermal resistance from junction to ambient, critical for derating power dissipation above 25 °C |
| TJ max | +150 °C - maximum junction temperature enabling operation in under-hood automotive environments |
| IFSM | 200 A - single half-sine surge rating (8.3 ms), supporting high-energy inductive switch-off events |
Pinout & Package
Package: SMC (DO-214AB) - surface-mount plastic case with matte tin-plated leads, 0.220–0.246 inch body width, 0.260–0.280 inch length, and cathode band marking for unidirectional polarity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Anode-side connection point | Connected to protected line; clamps to cathode when voltage exceeds VBR |
| Anode (non-banded end) | Reference/ground node | Typically tied to system ground or low-impedance return path for effective shunting |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and surge endurance per stress test requirements |
| Halogen-free & RoHS-compliant | HM3 suffix confirms compliance with environmental regulations and eliminates brominated flame retardants |
| Low incremental surge resistance | Enables tighter clamping (VC/VBR ratio ≈ 1.45) and faster response to sub-nanosecond transients |
| MSL Level 1 rating | Allows unlimited floor life and standard reflow without baking, reducing manufacturing overhead |
| Glass passivated junction | Improves long-term stability of VBR and reduces parameter drift under thermal and humidity stress |
Applications

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 = 110 °C/W), same VWM/VBR range | Limited to lower-energy transients; unsuitable for automotive load dump per ISO 7637-2 | Select only for space-constrained consumer electronics with <500 W surge exposure |
| SMCJ60A-M3/57T | Same electrical specs and SMC package, but commercial-grade (non-AEC-Q101) and standard RoHS (not halogen-free) | Acceptable for industrial automation where automotive qualification is not mandated | Choose when cost sensitivity outweighs halogen-free or automotive reliability requirements |
Compared with SMCJ60AHM3/H, SMAJ60AHE3/A offers reduced surge capacity and thermal performance in a smaller package, while SMCJ60A-M3/57T matches mechanical and electrical specs but lacks AEC-Q101 validation and halogen-free construction - making SMCJ60AHM3/H the sole choice for certified automotive designs requiring both reliability and environmental compliance.

FAQ
What does the 'HM3' suffix indicate in SMCJ60AHM3/H?
The HM3 suffix in SMCJ60AHM3/H denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. It confirms compliance with automotive reliability standards and environmental regulations, distinguishing it from commercial-grade variants like M3 (halogen-free, no AEC-Q101) or E3 (RoHS, no halogen-free or AEC-Q101). This makes SMCJ60AHM3/H suitable for under-hood automotive use cases.
Is SMCJ60AHM3/H unidirectional or bidirectional?
SMCJ60AHM3/H is a unidirectional TVS diode, indicated by the absence of 'CA' in its part number and presence of a cathode band marking. It conducts only in reverse bias above VBR and must be oriented with the banded end toward the protected line - unlike bidirectional types (e.g., SMCJ60CA) which protect both polarities without polarity sensitivity.
What is the clamping voltage of SMCJ60AHM3/H at its rated peak pulse current?
The clamping voltage (VC) of SMCJ60AHM3/H is 96.8 V at its rated peak pulse current (IPPM) of 15.5 A, measured using the standard 10/1000 µs waveform. This value represents the maximum voltage seen by downstream circuitry during a full 1500 W transient event, ensuring safe operation of 60 V-rated components connected to the protected line.
Does SMCJ60AHM3/H require special PCB layout considerations?
Yes - SMCJ60AHM3/H should be mounted using the minimum recommended pad layout (0.31" × 0.31" copper pads per terminal) to achieve specified thermal and surge performance. Short, low-inductance traces to ground are essential to minimize voltage overshoot during fast transients, and the cathode band must align correctly to ensure proper polarity-dependent clamping behavior.
How does SMCJ60AHM3/H perform under elevated ambient temperatures?
SMCJ60AHM3/H derates linearly above 25 °C ambient per Figure 2 in its datasheet: peak pulse power drops to ~75% at 70 °C and ~50% at 100 °C. Its RθJA of 75 °C/W and TJ max of +150 °C allow continued operation in hot environments, but designers must verify clamping voltage and surge margin at worst-case operating temperature using the published derating curves.
