Product details
Overview
SMPC58ANHM3/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in the TRANSZORB® family, designed for high-energy surge protection on power and signal lines. It features a 58 V stand-off voltage (VWM), 64.4–71.2 V breakdown voltage (VBR), 1500 W peak pulse power (10/1000 μs), 93.6 V maximum clamping voltage at 16 A IPPM, and operates within -55 °C to +150 °C junction temperature range. It is AEC-Q101 qualified and used in automotive sensor line protection.
For engineers reviewing the SMPC58ANHM3/I datasheet, SMPC58ANHM3/I pinout, SMPC58ANHM3/I application, or SMPC58ANHM3/I equivalent, this page delivers verified electrical parameters, package dimensions, thermal behavior, automotive qualification status, and real-world implementation context - all specific to the SMPC58ANHM3/I variant with HM3 suffix and I reel packaging.
Technical Context
The SMPC58ANHM3/I is a single-channel, unidirectional TVS diode built using planar silicon junction technology. Its clamping action begins at VBR ≥ 64.4 V under 1 mA test current and limits transients to ≤ 93.6 V at 16 A peak pulse current, enabling robust protection of downstream MOSFETs or ICs against ISO 7637-2 or IEC 61000-4-5 surges.
It utilizes the SMPC (TO-277A) surface-mount package with dual anode/cathode configuration - cathode marked by band - and achieves low incremental surge resistance and sub-nanosecond response time. Thermal performance is characterized by RθJA ≤ 100 °C/W (FR4, 2 oz copper) and RθJM ≤ 3 °C/W, supporting reliable operation under repetitive surge stress when mounted on heatsinked PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 58.0 V - Maximum continuous reverse operating voltage before clamping initiates; defines safe DC bias margin for protected circuitry. |
| VBR (min/max) | 64.4 V / 71.2 V at IT = 1 mA - Confirmed breakdown threshold range; ensures predictable turn-on during overvoltage events. |
| VC @ IPPM | 93.6 V at 16 A (10/1000 μs) - Clamped voltage seen by protected device; determines residual stress on downstream components. |
| PPPM | 1500 W - Peak pulse power handling capability; supports immunity to high-energy transients per ISO 7637-2 Pulse 5a. |
| TJ max | +150 °C - Maximum junction temperature rating; enables use in under-hood automotive environments without derating. |
| Package | SMPC (TO-277A) - 3-terminal SMD package with 1.1 mm profile; optimized for automated placement and thermal dissipation via cathode/anode pads. |
| Qualification | AEC-Q101 qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22. |
Pinout & Package
SMPC58ANHM3/I uses the SMPC (TO-277A) package: a 3-terminal surface-mount outline with 1.1 mm typical height, UL 94 V-0 molding compound, matte tin-plated leads, and cathode polarity indicated by a band. The device has dual anode terminals (pins 1 & 2) and a common cathode terminal (pin 3), enabling symmetrical layout and low-inductance mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (Pin 1) | Primary anode connection | Provides one path for forward conduction during clamping; electrically tied to Anode 2 internally in unidirectional configuration. |
| Anode 2 (Pin 2) | Secondary anode connection | Parallel anode terminal reducing series inductance and improving surge current sharing; required for rated PPPM performance. |
| Cathode (Pin 3, banded end) | Clamping output node | Common cathode where clamped voltage appears; must be routed with minimal trace inductance to protect sensitive loads. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional clamping | Enables integration into DC-biased power rails without reverse leakage concerns; blocks reverse current until VBR exceeded. |
| AEC-Q101 qualification | Validates suitability for automotive powertrain, body control, and ADAS modules requiring long-term reliability under thermal and mechanical stress. |
| Low-profile SMPC package | 1.1 mm height allows use in space-constrained modules such as ECUs and sensor housings while maintaining 1500 W surge capacity. |
| Halogen-free & RoHS-compliant | Meets global environmental compliance requirements for automotive and industrial manufacturing without compromising surge performance. |
| MSL Level 1 rating | Supports lead-free reflow up to 260 °C peak without moisture-induced damage; eliminates pre-bake requirement in SMT assembly. |
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 |
|---|---|---|---|
| SMAJ58A-E3/5A (Vishay) | DO-214AC package; 58 V VWM; 1500 W PPPM; same VBR/VC specs but higher RθJA (150 °C/W) and no AEC-Q101 qualification. | Limited to industrial/commercial use; unsuitable for automotive due to lack of AEC-Q101 validation and lower thermal robustness. | Select SMAJ58A-E3/5A only for cost-sensitive non-automotive designs where board space permits larger footprint and thermal margin is adequate. |
| TPSMA6L58A (Texas Instruments) | DO-214AC; 58 V VWM; 1500 W PPPM; AEC-Q101 qualified; slightly higher VC (95.5 V) and tighter VBR tolerance (64.4–67.6 V). | Functionally interchangeable in automotive applications but requires verification of layout compatibility due to different package thermal path. | Choose TPSMA6L58A when sourcing from TI's ecosystem or when tighter VBR distribution improves system margin in high-volume production. |
Compared with SMAJ58A-E3/5A and TPSMA6L58A, the SMPC58ANHM3/I offers superior thermal performance (RθJM ≤ 3 °C/W), lower profile (1.1 mm vs. 2.3 mm), and guaranteed AEC-Q101 compliance - making it optimal for space- and reliability-critical automotive modules where PCB real estate and under-hood thermal management are constrained.

FAQ
What is the exact breakdown voltage range for SMPC58ANHM3/I?
The SMPC58ANHM3/I has a specified breakdown voltage (VBR) range of 64.4 V to 71.2 V at 1 mA test current (IT), per Vishay Document 89116. This range ensures consistent clamping onset across production lots and supports design margining for automotive load-dump scenarios where voltage overshoot may exceed 60 V.
Is SMPC58ANHM3/I qualified for automotive use?
Yes, SMPC58ANHM3/I is AEC-Q101 qualified - explicitly confirmed in the ordering information table and features section of Vishay's datasheet (Rev. 17-Sep-2021). The HM3 suffix denotes halogen-free, RoHS-compliant, and AEC-Q101 validated construction, making it suitable for automotive powertrain, chassis, and body electronics.
What does the "I" suffix mean in SMPC58ANHM3/I?
The "I" suffix in SMPC58ANHM3/I indicates packaging in 13-inch diameter plastic tape and reel, with a base quantity of 6500 units per reel. This format supports high-speed automated placement in volume manufacturing and is distinct from the "H" suffix (7-inch reel, 1500 units), both compliant with EIA-481 standards.
How does SMPC58ANHM3/I differ from SMPC58A-M3/I?
SMPC58ANHM3/I is AEC-Q101 qualified (HM3 suffix), whereas SMPC58A-M3/I is industrial-grade only (M3 suffix). The "N" in SMPC58ANHM3/I denotes the AN variant - optimized for higher VWM/VBR consistency and tighter thermal specs - and is the only version qualified for automotive applications per Vishay's documentation.
What is the maximum clamping voltage of SMPC58ANHM3/I at rated surge current?
The SMPC58ANHM3/I clamps to a maximum of 93.6 V at its rated peak pulse current (IPPM) of 16 A under a 10/1000 μs waveform. This value is measured with cathode mounted on heatsink per standard test conditions and defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
