Product details
Overview
P4SMA62AHE3/5A from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping fast-rising ESD and surge 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 automotive and industrial control systems.
For engineers reviewing the P4SMA62AHE3/5A datasheet, P4SMA62AHE3/5A pinout, P4SMA62AHE3/5A application, or P4SMA62AHE3/5A equivalent, key selection criteria include its AEC-Q101 qualification, unidirectional polarity with cathode band marking, low thermal resistance (RθJL = 30 °C/W), and compliance with UL 497B for telecom and automotive surge protection.
Technical Context
The P4SMA62AHE3/5A operates as a clamping-type TVS diode, leveraging an avalanche breakdown mechanism to divert transient energy away from protected circuitry once voltage exceeds VBR. Its glass-passivated junction ensures stable breakdown characteristics and long-term reliability under repetitive surge stress.
It is rated for 400 W peak pulse power (10/1000 µs) up to TA = 25 °C, derating linearly above that temperature per Fig. 2, with a maximum junction temperature of +150 °C and thermal resistance of 120 °C/W (junction-to-ambient) on standard 5.0 mm × 5.0 mm copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 53.0 V - Maximum continuous reverse operating voltage before clamping begins; sets safe margin below system rail. |
| VBR (Breakdown Voltage) | 58.9–65.1 V at IT = 1 mA - Confirmed avalanche threshold range; defines precise clamping onset point. |
| VC (Clamping Voltage) | 85.0 V at IPPM = 4.7 A - Peak voltage seen by protected device during 10/1000 µs surge; determines downstream component stress. |
| PPPM (Peak Pulse Power) | 400 W - Sustains single 10/1000 µs transients without degradation; derates to 300 W above 91 V models (not applicable here). |
| IPPM (Peak Pulse Current) | 4.7 A - Maximum surge current handled at VC; directly correlates with IEC 61000-4-5 Level 3/4 capability. |
| TJmax | +150 °C - Enables operation in under-hood automotive and high-temperature industrial environments. |
| AEC-Q101 Qualified | Yes - Validated for automotive electronics per stress test requirements including HTOL, TC, and ESD. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile plastic case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102; meets UL 94 V-0 flammability rating and MSL level 1 (peak reflow 260 °C).
| Pin/Terminal | Circuit Role | Design Meaning |

| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in unidirectional configuration. |
| Cathode (marked with band) | Reverse-biased clamping terminal | Connected to protected line (e.g., 48 V supply rail); conducts avalanche current during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, high-temperature operating life, and ESD robustness. |
| Glass-passivated junction | Ensures stable VBR tolerance and low leakage (<1 µA at VWM) across temperature and lifetime. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ64A | VWM = 64 V, VBR = 71.1–78.6 V, VC = 103 V at 3.9 A - higher clamping voltage, lower IPPM. | Less effective clamping margin for 48 V systems; better suited for 60 V nominal rails. | Select when higher VWM margin is required and 103 V clamping is acceptable for downstream components. |
| 1.5SMC68A | Higher power rating (1500 W), larger SMC (DO-214AB) package, VWM = 58.1 V, VC = 113 V at 13.3 A - physically incompatible with SMA footprints. | Used where higher surge energy handling is needed but board space allows larger package. | Choose only if PCB layout permits SMC footprint and system requires >400 W surge capacity. |
Compared with SMAJ64A and 1.5SMC68A, the P4SMA62AHE3/5A offers optimal balance of compact SMA packaging, AEC-Q101 qualification, and tight 53.0 V/85.0 V VWM/VC ratio - making it preferred for space-constrained automotive and industrial 48 V designs requiring validated reliability.

FAQ
What is the maximum clamping voltage of the P4SMA62AHE3/5A under a 10/1000 µs surge?
The P4SMA62AHE3/5A has a maximum clamping voltage (VC) of 85.0 V at 4.7 A peak pulse current with a 10/1000 µs waveform. This value is measured per Figure 1 in the Vishay datasheet 88367 and represents the upper voltage limit imposed on protected circuitry during standardized surge testing. The P4SMA62AHE3/5A maintains this clamping performance across its qualified operating temperature range.
Is the P4SMA62AHE3/5A AEC-Q101 qualified, and what does that mean for automotive use?
Yes, the P4SMA62AHE3/5A carries the HE3 suffix, confirming full AEC-Q101 qualification per Vishay's ordering nomenclature. This means it has passed accelerated stress tests including high-temperature operating life (HTOL), temperature cycling (TC), and ESD (HBM/MM), validating suitability for automotive under-hood and cabin applications. The P4SMA62AHE3/5A is explicitly approved for use in BCMs, ADAS sensors, and infotainment power rails.
What is the standoff voltage (VWM) of the P4SMA62AHE3/5A, and how does it relate to system voltage?
The P4SMA62AHE3/5A has a standoff voltage (VWM) of 53.0 V - the maximum continuous reverse voltage it can block without entering breakdown. For reliable operation, VWM must exceed the system's maximum steady-state voltage (e.g., 48 V nominal rail with ±10% tolerance = 52.8 V), providing margin against false triggering. The P4SMA62AHE3/5A's 53.0 V VWM is thus optimized for 48 V automotive and industrial systems.
Does the P4SMA62AHE3/5A have polarity markings, and how is it oriented on the PCB?
Yes, the P4SMA62AHE3/5A is unidirectional and features a visible cathode band on the SMA (DO-214AC) package body. During PCB layout, the banded end must be connected to the line being protected (e.g., 48 V rail), while the anode connects to ground or return. Incorrect orientation renders the device non-functional for surge suppression. The P4SMA62AHE3/5A's polarity is confirmed in the "Mechanical Data" section of Vishay document 88367.
What is the thermal resistance and maximum junction temperature of the P4SMA62AHE3/5A?
The P4SMA62AHE3/5A has a typical junction-to-lead thermal resistance (RθJL) of 30 °C/W and a maximum junction temperature (TJmax) of +150 °C. Its junction-to-ambient resistance (RθJA) is 120 °C/W when mounted on 5.0 mm × 5.0 mm copper pads. These values allow the P4SMA62AHE3/5A to sustain repeated 400 W surges in ambient temperatures up to +125 °C when properly heatsinked via PCB copper.
