Product details
Overview
P4SMA62CAHE3/5A from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) in the P4SMA series, designed for clamping voltage transients on signal or power lines. It features a 62 V breakdown voltage (VBR min/max = 58.9 V / 65.1 V), 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 MOSFETs, sensor interfaces, and communication lines in automotive and industrial systems.
For engineers reviewing the P4SMA62CAHE3/5A datasheet, P4SMA62CAHE3/5A pinout, P4SMA62CAHE3/5A application, or P4SMA62CAHE3/5A equivalent, this device delivers AEC-Q101 qualification, SMA (DO-214AC) package compatibility, bidirectional surge suppression, and low incremental surge resistance - key selection criteria for robust ESD and lightning-induced transient protection in space-constrained PCB layouts.
Technical Context
The P4SMA62CAHE3/5A operates as a bidirectional avalanche diode, symmetrically clamping both positive and negative transients without polarity dependence. Its glass-passivated junction ensures stable breakdown behavior, while MSL Level 1 moisture sensitivity and 260 °C lead-free reflow compatibility support automated SMT assembly.
It delivers 400 W peak pulse power (derated to 300 W above 91 V), with thermal resistance RθJA = 120 °C/W and RθJL = 30 °C/W, enabling reliable operation up to TJ = +150 °C. The device exhibits 0.104 %/°C temperature coefficient of VBR, ensuring predictable voltage drift across operating temperature ranges.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA | Higher VBR (60.8–67.2 V), same SMA package, 600 W PPPM, but larger SMB (DO-214AA) footprint | Requires PCB layout change due to 4.58 mm × 3.94 mm vs. P4SMA's 4.50 mm × 2.79 mm body | Select when higher surge margin is needed and board space allows larger package |
| 1.5KE68CA | Through-hole TO-218 package, 68 V VBR, 1500 W PPPM, no AEC-Q101 qualification | Not suitable for automated SMT or automotive use; intended for legacy power supply designs | Choose only for manual assembly or high-power non-automotive applications where footprint is not constrained |
Compared with SMBJ64CA and 1.5KE68CA, the P4SMA62CAHE3/5A offers optimal balance of AEC-Q101 compliance, compact DO-214AC footprint, and precise 62 V clamping - making it the preferred choice for new automotive and space-sensitive industrial designs requiring verified reliability and SMT scalability.

FAQ
What is the clamping voltage of P4SMA62CAHE3/5A at its rated peak pulse current?
The P4SMA62CAHE3/5A has a maximum clamping voltage (VC) of 85.0 V at its rated peak pulse current (IPPM) of 4.7 A under a 10/1000 µs waveform. This value is measured per Figure 1 in Vishay document 88367 and defines the upper voltage limit imposed on protected circuitry during surge events. The P4SMA62CAHE3/5A maintains this clamping performance across its qualified operating temperature range.
Is P4SMA62CAHE3/5A suitable for automotive applications?
Yes, P4SMA62CAHE3/5A is AEC-Q101 qualified (indicated by the HE3 suffix), having passed stress tests including temperature cycling, high-temperature reverse bias, and ESD per JESD22 standards. Its DO-214AC package, 150 °C max junction temperature, and bidirectional clamping make it appropriate for under-hood and body-control module applications where transient immunity is critical. The P4SMA62CAHE3/5A meets automotive reliability requirements without derating.
What does the "CA" suffix mean in P4SMA62CAHE3/5A?
The "CA" suffix in P4SMA62CAHE3/5A denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional "A" variants, the CA version has no cathode band marking and functions identically in either orientation. This is essential for protecting AC-coupled lines, differential buses like CAN or RS-485, and floating sensor outputs where polarity is undefined. The P4SMA62CAHE3/5A leverages this feature for simplified layout and reduced BOM count.
What is the maximum steady-state power dissipation of P4SMA62CAHE3/5A?
The P4SMA62CAHE3/5A has a maximum steady-state power dissipation (PD) of 3.3 W at TA = 50 °C on an infinite heatsink. This rating reflects continuous DC or low-frequency reverse leakage power handling - distinct from its 400 W peak pulse capability. In typical PCB layouts with 5.0 mm × 5.0 mm copper pads per terminal, derating applies above 25 °C ambient, and thermal design must ensure junction temperature remains ≤150 °C. The P4SMA62CAHE3/5A's RθJA of 120 °C/W informs such calculations.
How does the HE3 suffix differ from E3 in P4SMA62CAHE3/5A?
The "HE3" suffix in P4SMA62CAHE3/5A indicates RoHS-compliant construction plus AEC-Q101 qualification, whereas "E3" alone denotes RoHS compliance only (commercial grade). HE3 devices undergo additional stress testing including 1000-hour high-temperature reverse bias, temperature cycling, and ESD verification per automotive standards. This makes P4SMA62CAHE3/5A suitable for safety-critical automotive subsystems where field reliability is mandated - a distinction not provided by standard E3 variants. The P4SMA62CAHE3/5A thus carries dual certification for both environmental and functional robustness.
