Product details
Overview
P4SMA13CAHE3/61 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, rated for 13 V breakdown voltage (VBR = 12.4–13.7 V at 1 mA), 11.1 V standoff voltage (VWM), and 18.2 V clamping voltage (VC) at 22 A peak pulse current - designed to protect sensitive signal lines and power rails in automotive-grade sensor interfaces and industrial control circuits.
For engineers reviewing the P4SMA13CAHE3/61 datasheet, P4SMA13CAHE3/61 pinout, P4SMA13CAHE3/61 application, or P4SMA13CAHE3/61 equivalent, this AEC-Q101 qualified TVS delivers verified 400 W peak pulse power (10/1000 µs), low incremental surge resistance, and MSL Level 1 moisture sensitivity - critical for high-reliability automotive electronics and industrial IoT edge nodes requiring robust ESD and lightning surge immunity.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical electrical characteristics in forward and reverse directions. Its glass-passivated junction ensures stable breakdown behavior and fast response time (<1 ns), enabling effective suppression of ESD (IEC 61000-4-2), EFT (IEC 61000-4-4), and surge transients (IEC 61000-4-5).
Thermally, it features RθJA = 120 °C/W and RθJL = 30 °C/W, supporting operation up to TJ = +150 °C. The device is rated for 3.3 W steady-state power dissipation on infinite heatsink at 50 °C ambient and withstands 40 A non-repetitive forward surge (8.3 ms half-sine) - applicable only to unidirectional variants; P4SMA13CAHE3/61 is bidirectional and thus excludes IFSM rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4 V / 13.7 V at 1 mA test current - defines precise voltage threshold where clamping initiates under transient stress |
| VWM | 11.1 V - maximum continuous working voltage before leakage exceeds 1 µA; sets safe operating margin below breakdown |
| VC @ IPPM | 18.2 V at 22 A peak pulse - actual clamped voltage seen by protected circuit during 10/1000 µs surge event |
| PPPM | 400 W (10/1000 µs waveform) - peak transient energy absorption capability without failure |
| Package | SMA (DO-214AC) - surface-mount package with 5.0 mm × 5.0 mm copper pad thermal layout, MSL Level 1, 260 °C reflow compatible |
| AEC-Q101 Qualified | Yes - validated for automotive applications including engine control modules, ADAS sensors, and body electronics |
| Leakage Current | <1 µA at VWM - ensures minimal standby power loss and signal integrity in low-power sensor interfaces |
Pinout & Package
Package: SMA (DO-214AC), bidirectional configuration - no polarity marking; symmetrical two-terminal construction with cathode/anode terminals interchangeable in circuit placement.
| Pin/Terminal | Circuit Role | Design Meaning |

| Consumer Smart Home Hub Power Rails | Telecom DSL/ADSL Line Card Protection |
Use Scenario: Shielding 3.3 V/5 V system rails in Wi-Fi/BLE hubs from ESD events during USB port hot-plug and button actuation. IC Role / Device Role / Timing Role: Low-capacitance TVS (CJ < 100 pF at VWM) placed directly at rail entry points to minimize parasitic loading on switching regulators. Use Value: Delivers <1 ns response and sub-µA leakage to prevent regulator instability or false resets during 8 kV contact ESD (IEC 61000-4-2). |
Use Scenario: Front-end protection of ADSL line drivers and SLIC circuits in residential gateways exposed to lightning-induced surges on twisted-pair telephone lines. IC Role / Device Role / Timing Role: Bidirectional clamping between tip/ring and ground to absorb longitudinal surges while maintaining impedance matching for 1 MHz–2.2 MHz DSL signals. Use Value: Withstands repetitive 10/1000 µs surges up to 400 W and maintains VC ≤18.2 V to avoid latch-up in line interface ICs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13CA | Same VBR range (12.4–13.7 V), but SMB package (DO-214AA); 600 W PPPM, higher thermal mass, RθJA = 90 °C/W | Better suited for higher-energy surges and less space-constrained layouts; not AEC-Q101 qualified in standard grade | Select when board area allows larger footprint and surge energy exceeds 400 W requirement |
| 1.5KE13CA | Through-hole DO-201AE package; 1500 W PPPM, same VBR/VC; higher IPPM (103 A), no AEC-Q101 qualification | Designed for legacy through-hole systems and high-power AC mains protection; incompatible with automated SMT assembly | Choose only for prototyping or repair of existing through-hole designs where rework is acceptable |
Compared with SMBJ13CA and 1.5KE13CA, P4SMA13CAHE3/61 offers optimal balance of AEC-Q101 compliance, compact SMA footprint, and sufficient 400 W surge rating for modern automotive and industrial PCBs - eliminating need for manual assembly or oversized footprints while guaranteeing automotive-grade reliability.

FAQ
What is the clamping voltage of P4SMA13CAHE3/61 at its rated peak pulse current?
The P4SMA13CAHE3/61 has a maximum clamping voltage (VC) of 18.2 V at 22 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per Figure 1 in Vishay document 88367 and represents the upper voltage limit imposed on protected circuitry during worst-case surge events - critical for ensuring downstream ICs like CAN transceivers remain within absolute maximum ratings.
Is P4SMA13CAHE3/61 suitable for automotive applications?
Yes, P4SMA13CAHE3/61 is AEC-Q101 qualified and explicitly designated for automotive use with ordering code suffix "HE3". It meets stress tests including temperature cycling, high-temperature reverse bias (HTRB), and ESD per JESD47, and is rated for operation from –65 °C to +150 °C junction temperature - making it appropriate for engine control units, body electronics, and ADAS sensor modules.
What does the "CA" suffix indicate in P4SMA13CAHE3/61?
The "CA" suffix in P4SMA13CAHE3/61 denotes a bidirectional configuration, meaning the device provides symmetrical transient suppression in both polarities. Unlike unidirectional variants (e.g., P4SMA13A), P4SMA13CAHE3/61 has no polarity marking and functions identically whether positive or negative transients occur - ideal for AC-coupled signal lines, differential buses, or floating power domains.
What is the standoff voltage (VWM) of P4SMA13CAHE3/61, and why does it matter?
The standoff voltage (VWM) of P4SMA13CAHE3/61 is 11.1 V - the maximum continuous DC or RMS voltage the device can block without exceeding 1 µA leakage current. This parameter establishes the safe operating margin below breakdown (VBR min = 12.4 V) and ensures minimal interference with normal circuit operation while providing headroom for voltage tolerances and ripple.
Does P4SMA13CAHE3/61 require special PCB layout considerations?
Yes - Vishay specifies mounting on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated 400 W peak pulse power. Reduced pad area causes thermal derating; the SMA package's RθJA = 120 °C/W assumes this layout. Additionally, keep traces short and direct between P4SMA13CAHE3/61 and protected node to minimize inductance that could elevate clamped voltage during fast transients.
