Product details
Overview
SMCJ58AHM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, with 58 V standoff voltage (VWM), 64.4–71.2 V breakdown voltage (VBR at 1 mA), 93.6 V clamping voltage (VC) at 16 A peak pulse current, and 1500 W peak pulse power rating for 10/1000 µs waveform. It protects MOSFETs, ICs, and sensor signal lines in automotive powertrain control modules against inductive switching transients.
For engineers reviewing the SMCJ58AHM3_A/I datasheet, SMCJ58AHM3_A/I pinout, SMCJ58AHM3_A/I application, or SMCJ58AHM3_A/I equivalent, this device is selected for high-energy surge immunity in 12 V/24 V automotive subsystems, industrial motor drives, and telecom power interfaces where AEC-Q101 qualification, halogen-free RoHS compliance, and low clamping ratio (<1.62×VWM) are required.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal bias it presents <1 µA leakage at 58 V; during transient overvoltage exceeding VBR, it avalanches rapidly (<1 ns response) to clamp the line at ≤93.6 V while diverting up to 16 A (10/1000 µs). Its glass-passivated junction ensures stable breakdown and low incremental surge resistance.
Designed for surface-mount assembly on PCBs with 8.0 mm × 8.0 mm copper pads per terminal, it meets MSL Level 1 per J-STD-020 (peak reflow 260 °C), supports automated placement, and delivers thermal resistance of 75 °C/W (junction-to-ambient) and 15 °C/W (junction-to-lead).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 58 V - Maximum continuous reverse operating voltage before conduction begins; sets upper limit for protected circuit's nominal rail. |
| VBR (min/max) | 64.4 V / 71.2 V at 1 mA - Confirmed breakdown range defining turn-on threshold; ensures reliable triggering above system overvoltage margin. |
| VC @ IPPM | 93.6 V at 16 A - Clamped voltage during full 1500 W surge; determines maximum stress imposed on downstream components. |
| PPPM | 1500 W - Peak pulse power handling for 10/1000 µs waveform; defines energy absorption capability for ISO 7637-2 Pulse 1/2a/5a events. |
| IFSM | 200 A - Non-repetitive forward surge current (8.3 ms half-sine); supports protection during load dump conditions in automotive 12 V systems. |
| TJ max | +150 °C - Maximum junction temperature; enables operation in under-hood environments without derating below 125 °C ambient. |
| Package | SMC (DO-214AB) - Standardized 2-pin surface-mount outline with 7.75 mm × 6.22 mm body; compatible with IPC-7351B footprint and pick-and-place tooling. |
Pinout & Package
Package: SMC (DO-214AB), molded plastic case with matte tin-plated leads; polarity indicated by cathode band on one end. Mounting requires 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal for rated power dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Anode-side connection for unidirectional clamping | Connected to protected line; conducts avalanche current to ground when transient exceeds VBR. |
| Anode (non-banded end) | Reference/ground return path | Typically tied to system ground plane; completes shunt path for surge current; must maintain low-inductance layout. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including powertrain and chassis modules; supports PPAP documentation and long-term reliability under thermal cycling. |
| Halogen-free & RoHS-compliant | Meets IEC 61249-2-21 and JEDEC JS709E; eliminates brominated flame retardants and antimony trioxide for safer end-of-life processing. |
| Low clamping ratio | VC/VWM = 1.61 - Minimizes overvoltage exposure to protected ICs; critical for safeguarding 60 V-rated MOSFETs and CAN transceivers. |
| MSL Level 1 rating | Reflow-compatible up to 260 °C peak; allows single-pass lead-free soldering without moisture sensitivity concerns or baking requirements. |
| Glass passivated junction | Stable VBR tolerance (±5%) and low leakage (<1 µA at VWM); ensures consistent performance across temperature and lifetime. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ58AHE3_A/I | Lower PPPM (400 W), smaller SMA package (DO-214AC), higher VC/VWM ratio (1.72) | Not AEC-Q101 qualified; limited to commercial-grade consumer/industrial use | Select when space-constrained layouts preclude SMC footprint and surge energy is ≤400 W. |
| SMCJ58AHE3_A/I | Same electrical specs but RoHS-compliant (non-halogen-free) and non-AEC-Q101 qualified | Approved for commercial/industrial use only; lacks automotive qualification documentation | Choose for cost-sensitive non-automotive designs requiring identical clamping performance without halogen-free or AEC-Q101 requirements. |
Compared with SMCJ58AHM3_A/I, SMAJ58AHE3_A/I offers reduced surge capacity and no automotive qualification, while SMCJ58AHE3_A/I matches key ratings but omits halogen-free construction and AEC-Q101 validation-making SMCJ58AHM3_A/I the sole option meeting all three criteria: 1500 W rating, halogen-free RoHS, and AEC-Q101.

FAQ
What is the clamping voltage of SMCJ58AHM3_A/I at its rated peak pulse current?
The SMCJ58AHM3_A/I has a maximum clamping voltage (VC) of 93.6 V when subjected to its rated peak pulse current of 16 A (10/1000 µs waveform). This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during surge events. The SMCJ58AHM3_A/I maintains this clamping performance across its specified operating temperature range of –55 °C to +150 °C.
Is SMCJ58AHM3_A/I qualified for automotive applications?
Yes, SMCJ58AHM3_A/I is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HM3" and documentation in datasheet 88394. This qualification covers stress testing for high-temperature operating life, temperature cycling, and mechanical shock-making SMCJ58AHM3_A/I suitable for under-hood automotive modules including engine control units and transmission controllers. The SMCJ58AHM3_A/I also meets MSL Level 1 for lead-free reflow compatibility.
What does the "HM3" suffix indicate in SMCJ58AHM3_A/I?
The "HM3" suffix in SMCJ58AHM3_A/I denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. Specifically, "H" indicates AEC-Q101 compliance, "M" signifies halogen-free molding compound, and "3" confirms RoHS compliance per EU Directive 2011/65/EU. This distinguishes SMCJ58AHM3_A/I from non-automotive variants like SMCJ58AHE3_A/I (RoHS only) and ensures material safety and automotive-grade reliability.
How does SMCJ58AHM3_A/I differ from bidirectional SMCJ58CA variants?
SMCJ58AHM3_A/I is unidirectional, featuring a cathode band and conducting only in reverse avalanche mode, whereas SMCJ58CA is bidirectional with symmetrical breakdown in both polarities and no polarity marking. The SMCJ58AHM3_A/I has a forward voltage drop (~3.5 V at 100 A) and is used where DC bias direction is fixed (e.g., 12 V rail to ground), while SMCJ58CA suits AC-coupled or floating signal lines. Their VBR, VC, and PPPM ratings are otherwise identical.
What PCB layout practices optimize thermal performance for SMCJ58AHM3_A/I?
To maximize thermal performance, SMCJ58AHM3_A/I requires 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal, as specified in Vishay's datasheet. Use internal ground/power planes connected via ≥4 thermal vias per pad (0.3 mm diameter, filled or capped), minimize trace length between TVS and protected node, and avoid routing high-speed signals near its terminals. These practices ensure the SMCJ58AHM3_A/I achieves its rated 1500 W pulse power and maintains RθJA ≤ 75 °C/W.
