Product details
Overview
P4SMA62AHM3/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping voltage transients on power and signal lines. It features a 53.0 V standoff voltage (VWM), 58.9–65.1 V breakdown voltage (VBR) at 1 mA, 85.0 V maximum clamping voltage (VC) at 4.7 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the P4SMA62AHM3/I datasheet, P4SMA62AHM3/I pinout, P4SMA62AHM3/I application, or P4SMA62AHM3/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification (HM3 suffix), halogen-free RoHS compliance, MSL Level 1 moisture sensitivity, and thermal resistance of 120 °C/W junction-to-ambient - critical for automotive-grade surge protection layout and reliability validation.
Technical Context
This TVS diode operates as a clamping device: under normal conditions it presents high impedance (>1 µA leakage at 53.0 V), but triggers into low-impedance conduction when transient voltage exceeds its 58.9–65.1 V breakdown range, limiting downstream voltage to ≤85.0 V at 4.7 A. Its glass-passivated junction ensures stable VBR tolerance and fast response (<1 ns).
Rated for 400 W peak pulse power (10/1000 µs), it delivers 300 W above 91 V per derating curve, with 40 A non-repetitive forward surge capability (8.3 ms half-sine). The SMA package supports automated placement and meets UL 94 V-0 flammability, J-STD-002 solderability, and JESD 201 Class 2 whisker resistance.

|---|---|---|---|
| SMAJ60A-E3/5A | Same SMA package, 60 V VWM, 66.7–73.7 V VBR, 96.8 V VC @ 4.1 A; 400 W rating; commercial-grade (not AEC-Q101). | Lacks automotive qualification and halogen-free certification; suitable for non-automotive industrial or telecom where AEC-Q101 is not mandated. | Select when cost sensitivity outweighs automotive compliance needs and 96.8 V clamping is acceptable for protected IC VDS margin. |

FAQ
What is the clamping voltage of the P4SMA62AHM3/I under a 10/1000 µs surge?
The P4SMA62AHM3/I has a maximum clamping voltage (VC) of 85.0 V at 4.7 A peak pulse current (IPPM) under a 10/1000 µs waveform. This value is measured per standard test conditions (TA = 25 °C, mounted on 0.2" × 0.2" copper pads) and defines the upper voltage limit imposed on protected circuitry during surge events. The P4SMA62AHM3/I maintains this clamping performance across its full operating temperature range.
Is the P4SMA62AHM3/I qualified for automotive applications?
Yes, the P4SMA62AHM3/I is AEC-Q101 qualified, as indicated by the "HM3" suffix in its part number. This qualification confirms successful completion of stress tests including high-temperature operating life, temperature cycling, and ESD per AEC-Q101 Rev D. The P4SMA62AHM3/I is rated for junction temperatures from -65 °C to +150 °C and is intended for use in automotive subsystems such as body electronics, infotainment, and ADAS sensor power rails.
What does the "HM3" suffix mean in P4SMA62AHM3/I?
The "HM3" suffix in P4SMA62AHM3/I denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. "H" indicates AEC-Q101 compliance, "M3" specifies halogen-free molding compound and matte tin plating, and "I" refers to 7500-unit reel packaging in 13-inch diameter tape. This distinguishes it from commercial variants (e.g., "E3") and ensures compliance with automotive environmental and reliability standards.
Can the P4SMA62AHM3/I be used in bidirectional configurations?
No, the P4SMA62AHM3/I is a unidirectional TVS diode, as confirmed by its part number suffix "A" (not "CA") and cathode band marking. Bidirectional operation requires CA-suffixed variants like P4SMA62CAHM3/I. Using P4SMA62AHM3/I in reverse-biased AC signal paths would result in forward conduction and potential failure; always verify polarity alignment in schematic and layout for the P4SMA62AHM3/I.
What is the thermal resistance of the P4SMA62AHM3/I, and how does it affect PCB layout?
The P4SMA62AHM3/I has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes minimal copper area; increasing pad size or adding thermal vias reduces RθJA. For reliable operation at full 400 W pulse rating, PCB layout must allocate sufficient copper to manage transient self-heating and avoid exceeding the +150 °C maximum junction temperature - especially in enclosed or high-ambient environments.
