Product details
Overview
SMBJ60AHM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) 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 range at 1 mA, 96.8 V maximum clamping voltage at 6.2 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform.
For engineers reviewing the SMBJ60AHM3_A/I datasheet, SMBJ60AHM3_A/I pinout, SMBJ60AHM3_A/I application, or SMBJ60AHM3_A/I equivalent, this device is selected for high-reliability surge suppression in automotive-grade industrial power supplies, sensor interface protection, and 24–48 V DC bus systems where halogen-free, AEC-Q101-qualified components are required.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-banded polarity, leveraging a glass-passivated silicon junction to achieve fast response (<1 ps) and low incremental surge resistance. Its thermal design supports operation up to +150 °C junction temperature, with RθJA = 100 °C/W and RθJL = 20 °C/W under standard PCB pad layout (0.2" × 0.2" copper).
The SMBJ60AHM3_A/I is rated for 100 A non-repetitive forward surge current (8.3 ms half-sine), exhibits ≤1.0 µA reverse leakage at VWM, and maintains stable clamping performance across -55 °C to +150 °C ambient range - meeting J-STD-020 MSL Level 1 and JEDEC JESD201 Class 2 whisker resistance requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60AHE3_A/I | Same electrical specs, but RoHS-compliant without halogen-free certification; uses standard molding compound. | Approved for commercial/industrial use, not automotive; lacks AEC-Q101 qualification. | Select when halogen-free requirement is not mandated and cost optimization is prioritized. |
| SMBJ60CAHM3_A/I | Bidirectional variant with symmetric VBR (66.7–73.7 V) and same clamping performance; no polarity marking. | Used in AC-coupled or differential signal lines (e.g., RS-485, CAN) requiring bidirectional protection. | Choose only if circuit topology demands symmetrical clamping - not a drop-in replacement for unidirectional designs. |
Compared with SMBJ60AHM3_A/I, the HE3 variant trades halogen-free compliance for broader commercial availability, while the CAHM3 variant changes fundamental polarity behavior - making it unsuitable for unidirectional DC rail protection without schematic revision.

FAQ
What is the clamping voltage of SMBJ60AHM3_A/I at its rated peak pulse current?
The SMBJ60AHM3_A/I has a maximum clamping voltage (VC) of 96.8 V at its specified peak pulse current (IPPM) of 6.2 A, measured using the standardized 10/1000 µs double-exponential waveform. This value is confirmed in the Vishay SMBJ5.0A–SMBJ188A datasheet (Document Number: 88392, Rev. 09-Jan-2024) and defines the upper voltage limit imposed on protected circuits during surge events. The SMBJ60AHM3_A/I maintains this clamping performance across its full operating temperature range.
Is SMBJ60AHM3_A/I qualified for automotive applications?
Yes, SMBJ60AHM3_A/I is AEC-Q101 qualified, as indicated by the "HM3" suffix and confirmed in the Vishay ordering information table (page 3). It meets the stress test requirements for automotive-grade discrete semiconductors, including temperature cycling, humidity bias, and mechanical shock. This qualification makes SMBJ60AHM3_A/I suitable for under-hood and chassis-mounted applications such as body control modules and ADAS sensor power conditioning - provided layout and thermal management follow Vishay's recommended pad dimensions.
What does the "HM3" suffix signify in SMBJ60AHM3_A/I?
The "HM3" suffix in SMBJ60AHM3_A/I denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. Per Vishay's ordering nomenclature (page 3), "HM3" distinguishes this variant from "HE3" (RoHS-compliant, AEC-Q101, but not halogen-free) and "M3" (halogen-free, RoHS-compliant, commercial grade only). The "_A/I" further specifies packaging: "A" indicates 7" tape-and-reel (750 pcs), and "I" denotes 13" tape-and-reel (3200 pcs) delivery mode.
How does SMBJ60AHM3_A/I differ from SMBJ60AHE3_A/I?
SMBJ60AHM3_A/I and SMBJ60AHE3_A/I share identical electrical parameters (VWM, VBR, VC, PPPM) and package, but differ in material compliance: HM3 is halogen-free and AEC-Q101 qualified, whereas HE3 is RoHS-compliant and AEC-Q101 qualified but not halogen-free. The HM3 variant uses a halogen-free molding compound meeting IEC 61249-2-21, making it preferred for automotive OEMs with strict chemical content requirements. Both are functionally interchangeable only if halogen-free status is not mandated.
What is the maximum reverse leakage current for SMBJ60AHM3_A/I at its standoff voltage?
The SMBJ60AHM3_A/I exhibits a maximum reverse leakage current (ID) of 1.0 µA at its rated standoff voltage (VWM) of 60 V, tested at TA = 25 °C. This low leakage ensures minimal power loss in always-on systems and preserves battery life in low-power sensor nodes. The specification is verified in the Electrical Characteristics table (page 2) of the Vishay SMBJ5.0A–SMBJ188A datasheet and remains stable up to 80 % of VWM across the full -55 °C to +125 °C operating range.
