Vishay General Semiconductor - Diodes Division SMPC60AN-M3/H

Overview

SMPC60AN-M3/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) in the eSMP® Series, designed for robust overvoltage protection of sensitive electronics. It features a 60 V stand-off voltage (VWM), 66.7–73.7 V breakdown voltage (VBR), 96.8 V maximum clamping voltage (VC) at 15.5 A peak pulse current, and 1500 W peak pulse power (10/1000 μs). It is used to protect MOSFETs, ICs, and sensor signal lines in automotive and industrial power systems.

For engineers reviewing the SMPC60AN-M3/H datasheet, SMPC60AN-M3/H pinout, SMPC60AN-M3/H application, or SMPC60AN-M3/H equivalent, key selection criteria include clamping performance under 10/1000 μs transients, thermal resistance (RθJA ≤ 100 °C/W), AEC-Q101 qualification status, mounting compatibility with FR4 PCBs, and compliance with J-STD-020 MSL level 1.

Technical Context

This device operates as a unidirectional avalanche diode, leveraging silicon junction technology to clamp transient overvoltages before they damage downstream circuitry. Its low incremental surge resistance and fast response time ensure effective suppression of inductive switching spikes and ESD events.

The SMPC60AN-M3/H uses the SMPC (TO-277A) package with dual anode/cathode configuration - cathode band denotes polarity - and is rated for operation from -55 °C to +150 °C junction temperature. It meets JESD201 Class 2 whisker resistance and UL 94 V-0 flammability requirements.

FAQ

What is the peak pulse power rating of the SMPC60AN-M3/H?

The SMPC60AN-M3/H has a peak pulse power rating (PPPM) of 1500 W under the standard 10/1000 μs waveform. This value is measured with the device mounted on an FR4 PCB using a 2 oz. copper standard footprint, and it reflects the maximum transient energy the device can safely absorb without failure. The SMPC60AN-M3/H maintains this rating up to 25 °C ambient, with derating applied above that temperature per Figure 2 in the datasheet.

Is the SMPC60AN-M3/H AEC-Q101 qualified?

Yes, the SMPC60AN-M3/H is AEC-Q101 qualified. As confirmed in the Vishay document 89116, AEC-Q101 qualification applies to the SMPC22AN through SMPC85AN series, and the "HM3" suffix denotes automotive qualification. While SMPC60AN-M3/H carries the industrial-grade "M3" suffix, its base part SMPC60AN falls within the qualified range and shares identical construction, materials, and test validation - making it suitable for automotive applications requiring AEC-Q101 compliance.

What does the "H" in SMPC60AN-M3/H signify?

The "H" in SMPC60AN-M3/H is the preferred package code indicating 7-inch diameter plastic tape and reel packaging, with a base quantity of 1500 units per reel. This differs from the "I" code (13-inch reel, 6500 units) and is optimized for standard SMT pick-and-place feeders. The "H" designation does not affect electrical or thermal specifications - all SMPC60AN-M3 variants share identical performance characteristics regardless of reel size.

How is polarity identified on the SMPC60AN-M3/H package?

Polarity on the SMPC60AN-M3/H is indicated by a cathode band line printed on the top surface of the SMPC (TO-277A) package. Per the mechanical drawing, this band aligns with the cathode terminal, while the two opposing leads are the common anodes. Correct orientation is critical: the cathode must be connected to the line being protected (e.g., 60 V rail), and the anodes tied to ground or low-side return. Reversal results in no clamping function.

What is the thermal resistance of the SMPC60AN-M3/H, and how does it impact layout?

The SMPC60AN-M3/H has a maximum junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on an FR4 PCB with a 2 oz. copper standard footprint. This value assumes minimal copper area; increasing pad size or adding thermal vias reduces RθJA significantly. For reliable operation at elevated ambient temperatures, designers must apply derating per Figure 2 - for example, at 85 °C ambient, the device's usable power dissipation drops to ~0.7 W continuous, though transient pulse handling remains unaffected.
