Product details
Overview
SMPC58AN-M3/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in the TRANSZORB® family, designed for high-energy surge protection on DC power rails and signal lines. It features a 58.0 V stand-off voltage (VWM), 64.4–71.2 V breakdown voltage (VBR), 93.6 V maximum clamping voltage (VC) at 16.0 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM) with 10/1000 μs waveform - deployed in automotive sensor interfaces and industrial power supply inputs.
For engineers reviewing the SMPC58AN-M3/I datasheet, SMPC58AN-M3/I pinout, SMPC58AN-M3/I application, or SMPC58AN-M3/I equivalent, key selection criteria include clamping performance under 16 A surge, thermal resistance (RθJA ≤ 100 °C/W), AEC-Q101 qualification status, and SMPC (TO-277A) package compatibility with automated SMT placement on FR4 PCBs.
Technical Context
This device operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its specified VBR range (64.4–71.2 V at 1.0 mA test current). Its low incremental surge resistance and fast response time enable effective suppression of ESD and inductive switching transients without latch-up or degradation under repetitive surges.
The SMPC58AN-M3/I uses a dual-anode/single-cathode configuration in the SMPC (TO-277A) package, where the cathode band identifies polarity. It is rated for operation from –55 °C to +150 °C junction temperature and meets JESD22-B102 solderability and JESD201 Class 2 whisker resistance standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 58.0 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 64.4 V / 71.2 V at 1.0 mA - ensures reliable turn-on within defined tolerance band |
| VC @ IPPM | 93.6 V at 16.0 A - limits downstream voltage stress during 10/1000 μs surge events |
| PPPM | 1500 W - supports high-energy transient absorption per JEDEC-standard waveform |
| RθJA | ≤ 100 °C/W - enables thermal management on standard 2 oz FR4 PCB footprint |
| Polarity | Unidirectional - protects against negative-going transients only; requires correct orientation |

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) | Same VWM (58 V), but SMA package (higher RθJA ≈ 140 °C/W); lower PPPM (400 W) | Limited to lower-energy surges; not AEC-Q101 qualified | Choose for cost-sensitive non-automotive designs where board space allows larger footprint |
| 1.5KE56A (ON Semiconductor) | Through-hole DO-201 package; 56 V VWM; 1500 W PPPM; no AEC-Q101 rating | Requires wave soldering; unsuitable for high-density SMT layouts | Select when legacy through-hole assembly is mandated or thermal mass of PCB supports higher RθJA |
Compared with SMAJ58A-E3/5A and 1.5KE56A, the SMPC58AN-M3/I delivers identical clamping performance in a smaller, AEC-Q101-qualified SMT package with superior thermal resistance - making it optimal for next-generation automotive and industrial edge nodes requiring zero-layout rework.

FAQ
What is the exact breakdown voltage range for SMPC58AN-M3/I?
The SMPC58AN-M3/I has a guaranteed breakdown voltage (VBR) range of 64.4 V to 71.2 V at 1.0 mA test current, measured per ANSI/IEEE C62.35 standards. This specification ensures consistent turn-on behavior across production lots and temperature ranges, critical for predictable clamping in automotive power domains where SMPC58AN-M3/I is commonly deployed.
Is SMPC58AN-M3/I AEC-Q101 qualified?
Yes, SMPC58AN-M3/I is AEC-Q101 qualified, as confirmed by Vishay's documentation for the SMPCxxAN series (Revision 17-Sep-2021, Doc. #89116). The "AN" suffix and M3/I packaging denote AEC-Q101 compliance, covering stress tests including temperature cycling, high-temperature operating life, and ESD robustness - essential for under-hood automotive applications using SMPC58AN-M3/I.
What does the "I" suffix mean in SMPC58AN-M3/I?
The "I" suffix in SMPC58AN-M3/I indicates packaging in 13-inch diameter plastic tape and reel, with a base quantity of 6500 units per reel. This format supports high-volume automated SMT placement and is distinct from the "H" suffix (7-inch reel, 1500 units), both compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance requirements for SMPC58AN-M3/I.
Can SMPC58AN-M3/I be used in bidirectional configurations?
No, SMPC58AN-M3/I is strictly unidirectional and must be oriented with the cathode band toward the protected line. Bidirectional protection requires either two SMPC58AN-M3/I devices in series opposition or a dedicated bidirectional TVS like SMBJ58CA. Using SMPC58AN-M3/I incorrectly in reverse bias risks permanent failure, as its design does not support positive-going transient suppression.
What is the maximum clamping voltage of SMPC58AN-M3/I at rated surge current?
The maximum clamping voltage (VC) of SMPC58AN-M3/I is 93.6 V at 16.0 A peak pulse current (IPPM) with a 10/1000 μs waveform, per Vishay's datasheet Figure 1 and Table on page 2. This value defines the upper voltage limit imposed on protected circuitry during worst-case surge events and is a key parameter for validating safe operation of downstream ICs powered by SMPC58AN-M3/I-protected rails.
