Product details
Overview
P4SMA62CAHE3/61 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P4SMA series, designed for clamping voltage transients on signal and power 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 (IPPM), and 400 W peak pulse power (10/1000 µs waveform). It is AEC-Q101 qualified and used in automotive sensor protection and industrial I/O line surge suppression.
For engineers reviewing the P4SMA62CAHE3/61 datasheet, P4SMA62CAHE3/61 pinout, P4SMA62CAHE3/61 application, or P4SMA62CAHE3/61 equivalent, this page delivers verified electrical parameters, package dimensions, clamping behavior under transient stress, thermal derating curves, and direct alternatives for automotive-grade circuit protection design.
Technical Context
The P4SMA62CAHE3/61 operates as a bidirectional avalanche diode, symmetrically clamping positive and negative transients without polarity dependence. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1 µA at VWM), while its DO-214AC (SMA) package supports automated placement and meets MSL Level 1 reflow requirements (260 °C peak).
It delivers 400 W peak pulse power per 10/1000 µs waveform up to 91 V; above that threshold, rating drops to 300 W. Thermal resistance is 120 °C/W (junction-to-ambient) and 30 °C/W (junction-to-lead), enabling reliable operation up to TJ = +150 °C with appropriate PCB copper pad layout (0.2" × 0.2").
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Standoff) | 53.0 V - Maximum continuous reverse working voltage before conduction begins; defines safe operating margin below clamping threshold. |
| VBR (Breakdown) | 58.9–65.1 V at IT = 1 mA - Voltage range where avalanche conduction initiates; tight tolerance ensures predictable turn-on across production lots. |
| VC (Clamping) | 85.0 V at IPPM = 4.7 A - Maximum voltage seen by protected circuit during 10/1000 µs transient; critical for IC-level overvoltage margining. |
| PPPM | 400 W (≤91 V), 300 W (>91 V) - Peak transient energy absorption capability; determines survivability against ISO 7637-2 Pulse 1/2/5a/b surges. |
| ID (Leakage) | <1 µA at VWM - Ultra-low reverse leakage preserves signal integrity and minimizes standby power loss in high-impedance nodes. |
| TJ max. | +150 °C - Maximum junction temperature; enables use in under-hood automotive environments and thermally constrained industrial enclosures. |
| Package | SMA (DO-214AC) - Standardized surface-mount outline with 2.54 mm lead pitch; compatible with JEDEC MS-013 and IPC-7351B footprint guidelines. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient return path (bidirectional) | Common terminal for both polarities; connects to protected line or ground reference depending on circuit topology. |
| Cathode | Transient return path (bidirectional) | Electrically identical to Anode in bidirectional configuration; no polarity marking required; symmetrical clamping behavior. |
Key Features
| Feature | Design Value |
|---|---|

Applications
| Automotive Sensor Protection | Industrial I/O Line Protection |
|---|---|
Use Scenario: Protecting CAN, LIN, or analog sensor signals (e.g., pressure, temperature) in vehicle ECUs from ISO 7637-2 pulses and ESD events. IC Role / Device Role / Timing Role: Bidirectional clamping element placed between signal line and chassis ground to limit transient voltage excursion. Use Value: Maintains signal integrity below 85.0 V clamping level during 4.7 A surge, preventing latch-up or damage to downstream MCU inputs. |
Use Scenario: Safeguarding RS-485, 4–20 mA loop, or digital input channels in PLCs and motor drives from lightning-induced surges and ground bounce. IC Role / Device Role / Timing Role: Fast-response TVS shunting transient energy away from interface ICs during sub-microsecond overvoltage events. Use Value: Low 1 µA leakage at 53.0 V VWM avoids loading high-impedance sensor outputs; 120 °C/W RθJA allows thermal management on standard FR4 PCBs. |
| Consumer Power Adapter Input | Telecom DC Power Rail Protection |
Use Scenario: Secondary-side transient suppression on 12–24 V DC outputs of wall adapters and USB-PD power supplies exposed to user-handling ESD. IC Role / Device Role / Timing Role: Standby-mode protector absorbing repetitive 10/1000 µs surges without thermal runaway. Use Value: 3.3 W steady-state power dissipation (PD) and +150 °C TJ max enable continuous operation in enclosed, unventilated enclosures. |
Use Scenario: DC feed protection for PoE-powered devices (e.g., IP cameras, wireless access points) subjected to induced surges on 48 V supply lines. IC Role / Device Role / Timing Role: Primary-stage TVS limiting rail voltage excursions before upstream DC-DC converters. Use Value: Symmetric 53.0 V VWM and 85.0 V VC ensure balanced clamping on positive/negative transients common in telecom infrastructure. |
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 | DO-214AA package; 64 V VWM; 70.1 V VC at 5.7 A; same 400 W PPPM rating but higher thermal resistance (RθJA = 140 °C/W). | Less compact footprint (5.3 mm × 4.6 mm vs. 4.93 mm × 3.99 mm); lower board density suitability. | Select when existing SMB layout exists or higher surge current margin is needed (5.7 A vs. 4.7 A). |
| SMCJ64CA | DO-214AB package; 64 V VWM; 104 V VC at 3.9 A; 1500 W PPPM rating; larger thermal mass but slower response due to higher junction capacitance. | Used in primary-side AC/DC input protection where higher energy handling outweighs speed constraints. | Choose for front-end surge suppression requiring >1 kW energy absorption, not for signal-line clamping. |
Compared with P4SMA62CAHE3/61, SMBJ64CA offers slightly higher clamping voltage and reduced board space efficiency, while SMCJ64CA trades faster response and tighter clamping for vastly higher energy capacity-making P4SMA62CAHE3/61 optimal for space-constrained, high-speed secondary-side protection in automotive and industrial systems.

FAQ
What is the clamping voltage of P4SMA62CAHE3/61 at its rated peak pulse current?
The P4SMA62CAHE3/61 has a maximum clamping voltage (VC) of 85.0 V at 4.7 A peak pulse current (IPPM), measured under the standardized 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuits during transient events and is confirmed in the Vishay datasheet revision 09-Jan-2024, page 2. The P4SMA62CAHE3/61 maintains this clamping performance across its full operating temperature range.
Is P4SMA62CAHE3/61 suitable for automotive applications?
Yes, P4SMA62CAHE3/61 is AEC-Q101 qualified and explicitly designated for automotive use with the "HE3" suffix indicating RoHS-compliant and AEC-Q101 qualified construction. It meets stringent requirements for under-hood and cabin electronics, including thermal cycling, humidity resistance, and surge immunity. The P4SMA62CAHE3/61 is referenced in Vishay's ordering table for automotive-grade variants (note 1, page 3).
What is the standoff voltage (VWM) and why does it matter for P4SMA62CAHE3/61?
The standoff voltage (VWM) of P4SMA62CAHE3/61 is 53.0 V - the maximum continuous reverse voltage the device can block without significant leakage. This parameter ensures the P4SMA62CAHE3/61 remains non-conductive during normal operation while providing sufficient margin below its 58.9–65.1 V breakdown range. It directly impacts system reliability: too low a VWM risks false triggering; too high reduces transient protection margin.
How does the bidirectional nature of P4SMA62CAHE3/61 affect its circuit implementation?
As a bidirectional TVS, P4SMA62CAHE3/61 provides symmetrical clamping for both positive and negative transients without polarity orientation constraints - no cathode marking is present. This simplifies layout on differential or AC-coupled lines (e.g., CAN bus, audio inputs) and eliminates risk of incorrect installation. The P4SMA62CAHE3/61 achieves identical VWM, VBR, and VC values in either direction, per Vishay's "DEVICES FOR BIDIRECTION APPLICATIONS" section.
What package type does P4SMA62CAHE3/61 use and what are its key mechanical attributes?
P4SMA62CAHE3/61 uses the SMA (DO-214AC) package: a compact surface-mount outline measuring 4.93 mm × 3.99 mm × 2.29 mm, with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. It meets UL 94 V-0 flammability rating and MSL Level 1 (260 °C peak reflow), enabling direct integration into high-volume SMT lines without pre-baking. The P4SMA62CAHE3/61 package is defined in Vishay's mechanical drawing on page 5.
