Product details
Overview
SMPC64AN-M3/I from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor in the SMPC (TO-277A) package, rated for 64 V stand-off voltage (VWM), 71.1–78.6 V breakdown voltage (VBR), and 1500 W peak pulse power (PPPM) with 10/1000 μs waveform. It provides low-clamping protection for automotive sensor signal lines, MOSFET gate drivers, and industrial I/O interfaces.
For engineers reviewing the SMPC64AN-M3/I datasheet, SMPC64AN-M3/I pinout, SMPC64AN-M3/I application, or SMPC64AN-M3/I equivalent, this device delivers AEC-Q101-qualified surge suppression with 103 V clamping voltage at 14.6 A IPPM, MSL Level 1 reflow compatibility, and halogen-free RoHS-compliant construction - critical for automotive-grade ESD and load-dump protection design validation.
Technical Context
This unidirectional TVS diode operates as a clamping device that conducts above its breakdown voltage to limit transient overvoltages across protected circuit nodes. Its low incremental surge resistance and fast response time ensure effective suppression of inductive switching spikes and lightning-induced surges on DC power rails and signal paths.
The SMPC64AN-M3/I uses a planar junction structure in a dual-anode/cathode configuration within the SMPC (TO-277A) package, enabling symmetrical thermal dissipation when mounted with either anode or cathode on heatsink - confirmed by the "Anode on heatsink / Cathode on heatsink" test condition in the datasheet clamping voltage table.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ64A-E3/5AT | DO-214AC (SMA) package; 64 V VWM; 1000 W PPPM; higher RθJA (150 °C/W) | Limited to lower-power industrial or consumer applications due to reduced surge rating and thermal performance | Choose when board space allows larger footprint and AEC-Q101 qualification is not required |
| SMCJ64A-M3/57T | SMC (DO-214AB) package; same 64 V VWM and 1500 W PPPM; 2.3 mm height; no AEC-Q101 option | Higher profile limits use in ultra-low-profile automotive modules; lacks automotive qualification documentation | Prefer when mechanical clearance permits and automotive compliance is not mandated |
Compared with SMAJ64A-E3/5AT and SMCJ64A-M3/57T, the SMPC64AN-M3/I offers AEC-Q101 qualification, 1.1 mm height for dense packaging, and identical 1500 W surge rating - making it the only option validated for under-hood automotive deployment where space, reliability, and regulatory compliance are jointly constrained.

FAQ
What is the clamping voltage of SMPC64AN-M3/I at its rated peak pulse current?
The SMPC64AN-M3/I has a maximum clamping voltage (VC) of 103 V at 14.6 A peak pulse current (IPPM) under 10/1000 μs waveform conditions. This value is measured with the cathode on heatsink per the datasheet test configuration and defines the upper voltage limit imposed on protected circuits during surge events. The SMPC64AN-M3/I maintains this clamping performance across its specified operating temperature range.
Is SMPC64AN-M3/I qualified for automotive applications?
Yes, SMPC64AN-M3/I is AEC-Q101 qualified, as confirmed by the "HM3" suffix designation in Vishay's ordering nomenclature and explicit listing in the datasheet's mechanical data section. This qualification covers stress testing for temperature cycling, humidity, mechanical shock, and high-temperature operating life - validating its suitability for engine control, body electronics, and ADAS subsystems. The SMPC64AN-M3/I carries the full AEC-Q101 certification documentation required for Tier 1 automotive procurement.
What does the "/I" suffix mean in SMPC64AN-M3/I?
The "/I" suffix in SMPC64AN-M3/I indicates packaging in 13-inch diameter plastic tape and reel, with a base quantity of 6500 units per reel. This delivery mode is optimized for high-volume SMT assembly lines using standard 13″ feeder systems. The "M3" prefix denotes halogen-free, RoHS-compliant, industrial-grade construction, while "AN" identifies the unidirectional variant with enhanced thermal derating characteristics versus non-"N" versions. The SMPC64AN-M3/I thus combines automotive-grade performance with high-throughput manufacturing readiness.
How does the SMPC64AN-M3/I thermal performance compare to standard SMA packages?
The SMPC64AN-M3/I achieves a typical junction-to-mount thermal resistance (RθJM) of 2.5 °C/W - significantly lower than SMA-packaged alternatives like SMAJ64A-E3/5AT (RθJM ≈ 15–20 °C/W). This superior thermal path results from its TO-277A metal-tab construction and dual-anode layout, allowing efficient heat transfer to PCB copper or external heatsinks. In practice, the SMPC64AN-M3/I sustains higher surge repetition rates and longer duty cycles in thermally demanding automotive environments compared to SMA devices.
What is the polarity configuration of SMPC64AN-M3/I and how is it identified on the device?
The SMPC64AN-M3/I is a unidirectional TVS diode with cathode-marked polarity: the end marked by a visible band is the cathode terminal, while the opposite side contains two electrically parallel anodes (Anode 1 and Anode 2). This configuration enables flexible mounting - either anode or cathode side can be placed against a heatsink without altering electrical behavior. The band orientation is consistent with JEDEC TO-277A mechanical drawings and verified in the datasheet's package outline diagram.
