Product details
Overview
P4SMA62AHE3_A/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 1.0 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 - suitable for protecting automotive-grade MOSFETs and sensor interfaces against inductive switching surges.
For engineers reviewing the P4SMA62AHE3_A/I datasheet, P4SMA62AHE3_A/I pinout, P4SMA62AHE3_A/I application, or P4SMA62AHE3_A/I equivalent, this AEC-Q101 qualified TVS offers verified unidirectional surge suppression, low incremental surge resistance, fast response time, and RoHS-compliant matte tin-plated leads - critical for automotive ECU, industrial I/O, and telecom line protection designs requiring MSL Level 1 reflow compatibility and 150 °C junction temperature operation.
Technical Context
The P4SMA62AHE3_A/I operates as a unidirectional clamping device: reverse-biased during normal operation with ≤1.0 µA leakage at 53.0 V, then rapidly avalanches above its 58.9–65.1 V breakdown threshold to limit transient energy. Its glass-passivated junction ensures stable VBR tolerance and low temperature coefficient (0.104 %/°C), while the SMA package provides thermal resistance of 120 °C/W (junction-to-ambient) and 30 °C/W (junction-to-lead).
Rated for 400 W peak pulse power (10/1000 µs), it delivers 4.7 A peak pulse current (IPPM) with 85.0 V clamping voltage - enabling robust protection of 5 V–24 V rail systems without compromising signal integrity. The device meets JESD201 Class 2 whisker resistance and is qualified per AEC-Q101 for automotive under-hood and chassis applications.
Key Specifications

| TJmax | +150 °C - Enables operation in under-hood automotive environments and industrial enclosures without derating |
| AEC-Q101 Qualified | Yes - Validated for automotive reliability including temperature cycling, HTRB, and ESD; suffix HE3 denotes qualification |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD22-B102; polarity indicated by cathode band on unidirectional devices.

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-E3/5A | 64 V VWM, 71.1–78.6 V VBR, 103 V VC at 3.9 A; same SMA package but higher clamping voltage | Less effective clamping margin for 53 V systems; better suited for 64 V nominal rails | Select only if system VWM requires ≥64 V standoff and higher VC is acceptable |
| 1.5SMC62A | 62 V VWM, 68.9–76.2 V VBR, 101 V VC at 3.9 A; larger SMC (DO-214AB) package, 1500 W rating | Higher power handling but 3× footprint; not drop-in compatible due to different pad layout and thermal mass | Choose for higher-energy transients where board space allows SMC package and thermal design supports 1500 W |
Compared with P4SMA62AHE3_A/I, SMAJ64A-E3/5A offers higher standoff but sacrifices clamping tightness, while 1.5SMC62A trades compactness for surge capacity - making P4SMA62AHE3_A/I optimal for space-constrained AEC-Q101 applications needing precise 53 V protection with minimal VC overhead.

FAQ
What is the clamping voltage of P4SMA62AHE3_A/I at its rated peak pulse current?
The P4SMA62AHE3_A/I has a maximum clamping voltage (VC) of 85.0 V at 4.7 A peak pulse current (IPPM) under 10/1000 µs waveform conditions. This value is measured per Figure 1 in the Vishay datasheet 88367 and defines the upper voltage limit imposed on protected circuits during surge events. The P4SMA62AHE3_A/I maintains this clamping performance across its specified operating temperature range and is validated for AEC-Q101 automotive use.
Is P4SMA62AHE3_A/I suitable for bidirectional transient suppression?
No, P4SMA62AHE3_A/I is a unidirectional TVS diode, as indicated by the "A" suffix and absence of "CA" in the part number. It conducts only in reverse bias (cathode-to-anode) and must be oriented with the cathode band toward the protected line. For bidirectional protection, Vishay specifies parts like P4SMA62CA; using P4SMA62AHE3_A/I in bidirectional configurations would leave positive-going transients unclamped.
What does the "HE3_A/I" suffix in P4SMA62AHE3_A/I signify?
The "HE3" suffix denotes RoHS-compliant construction with AEC-Q101 qualification; "A" indicates the revision code per Vishay's ordering matrix; "I" specifies packaging in 13-inch tape-and-reel format with 7500 units per reel. This distinguishes P4SMA62AHE3_A/I from variants like P4SMA62AHE3_A/H (7-inch reel, 1800 units) and confirms automotive-grade reliability testing per AEC-Q101.
What is the maximum junction temperature rating for P4SMA62AHE3_A/I?
The P4SMA62AHE3_A/I has a maximum junction temperature (TJmax) of +150 °C, as specified in the Absolute Maximum Ratings table of Vishay document 88367. This rating enables reliable operation in under-hood automotive environments and sealed industrial enclosures. Derating curves in Figure 2 confirm usable power dissipation down to ambient temperatures of -65 °C.
How does the thermal resistance of P4SMA62AHE3_A/I affect PCB layout?
P4SMA62AHE3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W and junction-to-lead (RθJL) of 30 °C/W. To maintain TJ ≤150 °C at full 3.3 W steady-state dissipation, PCB copper pads must follow Vishay's recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) layout per terminal. Smaller pads increase RθJA, risking thermal runaway during repetitive surges.
