Product details
Overview
SMPC58AN-M3/H from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor in the SMPC (TO-277A) package, rated for 58 V stand-off voltage (VWM), 64.4–71.2 V breakdown voltage (VBR), and 1500 W peak pulse power (PPPM) with 93.6 V clamping voltage at 16 A. It provides robust protection for MOSFETs and ICs against inductive switching transients in automotive sensor signal lines.
For engineers reviewing the SMPC58AN-M3/H datasheet, SMPC58AN-M3/H pinout, SMPC58AN-M3/H application, or SMPC58AN-M3/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, 1.1 mm profile height, MSL Level 1 moisture sensitivity, and thermal resistance (RθJA = 100 °C/W) on FR4 PCB.
Technical Context
This device operates as a silicon avalanche diode designed to clamp transient overvoltages by entering avalanche breakdown when reverse voltage exceeds VBR. Its low incremental surge resistance and fast response time ensure effective suppression of 10/1000 μs waveform surges without damage to downstream circuitry.
The SMPC58AN-M3/H uses a dual-anode/single-cathode configuration in the SMPC (TO-277A) package, where the cathode band denotes polarity. It is halogen-free, RoHS-compliant, and qualified to AEC-Q101 - confirmed by the "HM3" suffix variant - though the -M3/H version is industrial grade per base P/N-M3 designation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 58.0 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR (min/max) | 64.4 V / 71.2 V at 1.0 mA - ensures reliable avalanche turn-on within defined tolerance |
| VC @ IPPM | 93.6 V at 16.0 A - clamping voltage during 10/1000 μs surge, limiting stress on protected IC |
| PPPM | 1500 W - peak transient power handling capability under standardized surge waveform |
| TJ max | +150 °C - maximum junction temperature enabling operation in under-hood automotive environments |
| RθJA | 100 °C/W - thermal resistance from junction to ambient on standard FR4 PCB, guiding heatsinking needs |
| Polarity | Unidirectional - protects against positive transients only; requires correct orientation in circuit |
Pinout & Package
Package: SMPC (TO-277A), surface-mount, 3-terminal configuration with 1.1 mm typical height, matte tin-plated leads, and cathode band marking. Complies with JEDEC TO-277A mechanical outline and UL 94 V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 | Primary current path anode | Connected to protected line; forms one half of dual-anode structure for current sharing |
| Anode 2 | Secondary current path anode | Parallel anode terminal - both anodes must be connected identically for rated performance |
| Cathode | Avalanche conduction terminal | Connected to ground or reference; band-marked end; carries full surge current during clamping |
Key Features
| Feature | Design Value |
|---|---|
| Very low profile (1.1 mm) | Enables use in space-constrained automotive ECUs and portable industrial sensors without height interference |
| AEC-Q101 qualified option available | SMPC58ANHM3/H variant meets automotive reliability standards; -M3/H is industrial grade but shares identical die and package |
| MSL Level 1 (260 °C peak) | Supports standard lead-free reflow without preconditioning, reducing manufacturing complexity |
| Low incremental surge resistance | Minimizes voltage overshoot during fast transients, improving protection margin for 3.3 V/5 V logic interfaces |
| Halogen-free & RoHS-compliant | Fulfills environmental compliance requirements for global OEM and industrial equipment shipments |
Applications
| Automotive Sensor Signal Protection | Industrial Motor Drive Gate Protection |

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 | DO-214AC package, 58 V VWM, 93.6 V VC @ 15.3 A, 400 W PPPM | Lower power rating limits use to lower-energy transients; not AEC-Q101 qualified | Select when board space allows larger footprint and surge energy is ≤400 W |
| SMCJ58A | DO-214AB package, 58 V VWM, 93.6 V VC @ 16.0 A, 1500 W PPPM, same clamping | Larger 2.5 mm height and 7.1 mm length increase layout area; no AEC-Q101 option | Choose when higher thermal mass is needed and 1.1 mm height constraint does not apply |
Compared with SMAJ58A-E3/5A and SMCJ58A, the SMPC58AN-M3/H delivers identical 58 V/1500 W protection in a 30 % lower profile and supports automotive-grade variants, making it optimal for next-generation compact, high-reliability modules where vertical clearance and qualification matter.

FAQ
What is the polarity configuration of SMPC58AN-M3/H?
The SMPC58AN-M3/H is a unidirectional transient voltage suppressor with dual-anode and single-cathode terminals. The cathode is marked by a band on the package body, and both anodes must be connected identically in the circuit to achieve specified electrical performance per Vishay Document 89116.
Is SMPC58AN-M3/H AEC-Q101 qualified?
No - SMPC58AN-M3/H is industrial grade. The AEC-Q101 qualified version is SMPC58ANHM3/H (with HM3 suffix). Both share identical die, package, and electrical specs, but only the HM3 variant has undergone full automotive qualification testing per AEC-Q101 Rev D.
What is the mounting pad layout recommendation for SMPC58AN-M3/H?
Vishay specifies a standard FR4 PCB footprint with 0.268" × 0.186" (6.80 mm × 4.72 mm) pad area, 0.050" (1.27 mm) minimum solder mask opening, and 0.041" (1.04 mm) conductor width. Thermal relief is recommended for cathode pad due to high surge current handling.
Can SMPC58AN-M3/H be used in bidirectional applications?
No - SMPC58AN-M3/H is strictly unidirectional. For bidirectional protection, two devices must be connected in series opposing configuration, or a dedicated bidirectional part like SMPC58CA must be selected. Using SMPC58AN-M3/H in reverse bias beyond VWM risks permanent degradation.
What is the surge current rating for SMPC58AN-M3/H at elevated ambient temperatures?
Per Figure 2 in Vishay Document 89116, the 16.0 A peak pulse current (IPPM) is derated linearly above TA = 25 °C: at 85 °C ambient, IPPM drops to approximately 11.2 A. Full derating curve is provided in the datasheet for precise thermal design validation.
