Product details
Overview
SMBJ60AHM3/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in the SMB (DO-214AA) package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. 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 6.2 A peak pulse current, and 600 W peak pulse power rating with a 10/1000 µs waveform.
For engineers reviewing the SMBJ60AHM3/I datasheet, SMBJ60AHM3/I pinout, SMBJ60AHM3/I application, or SMBJ60AHM3/I equivalent, this device is selected for robust overvoltage protection on DC power rails and signal lines in industrial motor drives, automotive ECUs, and telecom interface circuits where fast response (<1 ns), low clamping ratio, and AEC-Q101 qualification are critical.
Technical Context
The SMBJ60AHM3/I operates as a unidirectional avalanche diode, conducting only in reverse bias above its breakdown threshold to clamp transient energy into ground. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low leakage (<1.0 µA at VWM), while its low incremental surge resistance enables consistent clamping performance under repetitive 10/1000 µs pulses at 0.01% duty cycle.
Designed for surface-mount assembly on standard PCB copper pads (0.2" × 0.2"), it delivers thermal resistance of 100 °C/W (junction-to-ambient) and supports operating junction temperatures from –55 °C to +150 °C. The HM3 suffix confirms halogen-free, RoHS-compliant construction and AEC-Q101 qualification - verified per stress test conditions including high-temperature operating life and temperature cycling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse working voltage before clamping begins; defines safe DC operating margin. |
| VBR (min/max) | 66.7 V / 73.7 V at IT = 1 mA - Tight breakdown window ensures predictable turn-on without premature conduction. |
| VC @ IPPM | 96.8 V at 6.2 A - Clamping voltage during 10/1000 µs surge; limits downstream IC stress to <97 V. |
| PPPM | 600 W - Peak pulse power handling capability; sustains 6.2 A surge without failure under standardized waveform. |
| IPPM | 6.2 A - Peak pulse current corresponding to VC; used to size series impedance and verify protection margin. |
| Junction Temp Range | –55 °C to +150 °C - Enables deployment in under-hood automotive and industrial environments without derating. |
| Leakage Current | <1.0 µA at 60 V - Negligible standby power loss and minimal impact on high-impedance sensor or reference circuits. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, molded plastic case with matte tin-plated leads; polarity indicated by cathode band on one end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal (cathode-banded side is opposite) | Connected to protected line (e.g., +12 V rail); conducts surge current toward ground when reverse-biased beyond VBR. |
| Cathode | Reverse-bias terminal (marked with band) | Connected to system ground; establishes clamping reference and provides low-impedance path for transient energy dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and body electronics per stress test requirements. |
| Halogen-free & RoHS-compliant (HM3) | Meets environmental compliance mandates for global OEM supply chains without compromising surge robustness. |
| 600 W peak pulse power (10/1000 µs) | Provides single-event surge immunity exceeding IEC 61000-4-5 Level 4 (4 kV) on 2 Ω source impedance lines. |
| Low clamping ratio (VC/VWM = 1.61) | Minimizes overvoltage overshoot across protected ICs, reducing risk of gate oxide damage in MOSFETs and logic inputs. |
| MSL Level 1 (260 °C reflow) | Enables standard lead-free SMT assembly without moisture sensitivity concerns or pre-bake requirements. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60AHE3/I | Same electrical specs; RoHS-compliant but not halogen-free; lacks AEC-Q101 qualification. | Suitable for commercial-grade industrial equipment where automotive qualification is not required. | Select when cost sensitivity outweighs halogen-free or automotive compliance needs. |
| SMAJ60AHE3/A | Lower 400 W PPPM, SMA package (smaller footprint, higher RθJA = 140 °C/W), same VWM/VC. | Used where board space is constrained and surge energy is limited to <400 W (e.g., low-power IoT sensors). | Choose only if layout constraints prevent SMB placement and surge threat level is reduced. |
Compared with SMBJ60AHM3/I, the HE3/I alternative trades halogen-free construction and AEC-Q101 validation for lower cost, while the SMAJ60AHE3/A reduces surge capacity and thermal performance to fit tighter layouts - neither offers pin-compatible replacement without verifying PCB pad design and thermal margin.

FAQ
What is the clamping voltage of SMBJ60AHM3/I at its rated peak pulse current?
The SMBJ60AHM3/I has a maximum clamping voltage (VC) of 96.8 V at its specified peak pulse current (IPPM) of 6.2 A, measured under the standardized 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during surge events and is confirmed in Vishay's datasheet revision 09-Jan-2024, page 2. The SMBJ60AHM3/I maintains this clamping performance across its full operating temperature range.
Is SMBJ60AHM3/I suitable for automotive applications?
Yes, SMBJ60AHM3/I is AEC-Q101 qualified, as explicitly stated in the Vishay datasheet (page 3, footnote 1). The HM3 suffix denotes halogen-free, RoHS-compliant construction validated for automotive use, including temperature cycling, high-temperature operating life, and mechanical shock testing. Engineers deploying SMBJ60AHM3/I in engine control units or ADAS power supplies can rely on its certified robustness.
What does the "HM3" suffix mean in SMBJ60AHM3/I?
The "HM3" suffix in SMBJ60AHM3/I indicates halogen-free, RoHS-compliant packaging with AEC-Q101 qualification. Per Vishay's ordering information (page 3), HM3 parts meet JESD201 Class 2 whisker resistance and UL 94 V-0 flammability standards. This distinguishes SMBJ60AHM3/I from E3 (RoHS only) and HE3 (AEC-Q101 but not halogen-free) variants - a critical specification for automotive and green-electronics compliance.
How does SMBJ60AHM3/I differ from SMBJ60AHE3/I?
SMBJ60AHM3/I and SMBJ60AHE3/I share identical electrical parameters (VWM, VBR, VC, PPPM) but differ in material compliance and qualification: HM3 is halogen-free and AEC-Q101 qualified, while HE3 is RoHS-compliant and AEC-Q101 qualified but contains halogens. The HM3 variant meets stricter environmental mandates for Tier 1 automotive suppliers, whereas HE3 serves cost-sensitive commercial applications where halogen content is unrestricted.
What is the thermal resistance of SMBJ60AHM3/I, and how does it affect layout?
SMBJ60AHM3/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on minimum recommended 0.2" × 0.2" copper pads per terminal. This value assumes standard FR-4 PCB layout; reducing pad area or omitting thermal vias increases junction temperature during repetitive surges. For sustained operation near 150 °C max, designers must ensure adequate copper area and avoid routing heat-sensitive components adjacent to SMBJ60AHM3/I.
