Product details
Overview
P4SMA62CAHE3_A/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) in SMA (DO-214AC) package, designed for clamping voltage transients on signal and power lines. It features 62 V breakdown voltage (VBR min/max = 58.9–65.1 V at 1 mA), 53.0 V standoff voltage (VWM), 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 in automotive sensor protection and industrial I/O interface surge suppression.
For engineers reviewing the P4SMA62CAHE3_A/I datasheet, P4SMA62CAHE3_A/I pinout, P4SMA62CAHE3_A/I application, or P4SMA62CAHE3_A/I equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 120 °C/W), junction temperature range (–65 to +150 °C), and bidirectional clamping behavior confirmed per Vishay Document 88367 (Rev. 09-Jan-2024).
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with no polarity marking on the device body. Its glass-passivated junction enables fast response time (<1 ns) and low incremental surge resistance, critical for suppressing ESD and lightning-induced transients on bidirectional data lines like RS-485 or CAN bus interfaces.
The device is rated for 400 W peak pulse power (10/1000 µs) up to 91 V, derating to 300 W above that threshold. It meets MSL Level 1 per J-STD-020, supports 260 °C lead-free reflow, and is AEC-Q101 qualified - confirming suitability for automotive under-hood and infotainment subsystems requiring robust transient immunity.
Key Specifications

Applications
| Automotive Sensor Interface Protection | Industrial RS-485 Data Line Protection |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA | Higher VWM (55.1 V), same VC (103 V @ 3.9 A), SMB package (larger footprint) | Lower power density (600 W but larger size); less suitable for space-constrained automotive modules | Select when higher surge margin is needed and board area permits SMB footprint |
| 1.5KE68CA | Through-hole TO-218 package, same VBR range, 1500 W rating but slower response due to parasitic inductance | Not suitable for high-frequency transients or automated SMT assembly; limited to legacy designs | Choose only for through-hole prototyping or repair of legacy equipment where SMT is unavailable |
Compared with P4SMA62CAHE3_A/I, SMBJ64CA offers higher surge margin but requires 3× more PCB area, while 1.5KE68CA sacrifices response speed and manufacturability for raw power - making P4SMA62CAHE3_A/I optimal for AEC-Q101-compliant, space-constrained SMT designs demanding fast, repeatable clamping.

FAQ
What is the clamping voltage of P4SMA62CAHE3_A/I at its rated peak pulse current?
The P4SMA62CAHE3_A/I has a maximum clamping voltage (VC) of 85.0 V at 4.7 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per Vishay Document 88367 and ensures downstream components remain within safe voltage limits during surge events. The clamping performance is symmetrical in both directions due to its bidirectional design.
Is P4SMA62CAHE3_A/I qualified for automotive applications?
Yes, P4SMA62CAHE3_A/I is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3" and documentation in Revision 09-Jan-2024 of Document 88367. This qualification covers temperature cycling, high-temperature reverse bias, and ESD testing - validating its use in automotive powertrain, chassis, and infotainment systems where reliability under harsh conditions is mandatory.
What does the "CA" suffix indicate in P4SMA62CAHE3_A/I?
The "CA" suffix in P4SMA62CAHE3_A/I denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression in both polarities, with no anode/cathode distinction. This is essential for protecting AC-coupled or differential signal paths (e.g., CAN, RS-485), unlike unidirectional "A" variants which require correct polarity orientation during placement.
What is the standoff voltage (VWM) of P4SMA62CAHE3_A/I, and why does it matter?
The standoff voltage (VWM) of P4SMA62CAHE3_A/I is 53.0 V - the maximum continuous DC or RMS voltage the device can withstand without exceeding 1 µA leakage current. This parameter ensures the TVS remains non-conductive during normal operation while still triggering reliably during transients exceeding ~58.9 V (VBR min), preventing false triggering or power loss in 48 V or 53 V nominal systems.
How does the SMA (DO-214AC) package of P4SMA62CAHE3_A/I impact thermal performance?
The SMA (DO-214AC) package of P4SMA62CAHE3_A/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 directly determines safe power dissipation limits: at 25 °C ambient, the device can sustain ~3.3 W continuously, but transient surge handling relies on short-duration thermal mass rather than steady-state conduction.
