Product details
Overview
P4SMA13CAHE3/5A 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 or power lines. It features a 13 V breakdown voltage (VBR min/max = 12.4 V / 13.7 V at 1.0 mA), 11.1 V standoff voltage (VWM), and clamps to ≤18.2 V at 22.0 A peak pulse current (10/1000 µs), delivering 400 W peak pulse power capability. It is AEC-Q101 qualified and used for protecting MOSFETs, sensor signal lines, and ICs in automotive and industrial control systems.
For engineers reviewing the P4SMA13CAHE3/5A datasheet, P4SMA13CAHE3/5A pinout, P4SMA13CAHE3/5A application, or P4SMA13CAHE3/5A equivalent, key selection criteria include bidirectional clamping behavior, 11.1 V working voltage, 18.2 V maximum clamping voltage at rated IPPM, AEC-Q101 qualification status, and SMA (DO-214AC) package compatibility with automated SMT placement.
Technical Context
The P4SMA13CAHE3/5A operates as a bidirectional avalanche diode, symmetrically clamping transient overvoltages in both polarities without polarity marking. Its glass-passivated junction enables fast response time (<1 ns) and low incremental surge resistance, critical for suppressing ESD and inductive switching spikes.
It delivers 400 W peak pulse power (10/1000 µs waveform) up to 91 V, derating to 300 W above that threshold. With a thermal resistance of 120 °C/W (junction-to-ambient) and 30 °C/W (junction-to-lead), it supports reliable operation under repetitive surge conditions when mounted on recommended 5.0 mm × 5.0 mm copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4 V / 13.7 V at 1.0 mA - defines precise avalanche initiation range for consistent clamping onset |
| VWM | 11.1 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | ≤18.2 V at 22.0 A - clamping voltage limiting stress on downstream circuitry during surge |
| PPPM | 400 W (10/1000 µs) - peak transient energy absorption capacity under standard surge waveform |
| IPPM | 22.0 A - maximum non-repetitive surge current the device safely conducts without failure |
| TJ max. | +150 °C - maximum junction temperature enabling use in under-hood automotive environments |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile plastic case with matte tin-plated leads; meets UL 94 V-0 flammability rating and JESD 201 Class 2 whisker resistance.

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 IPPM (33.0 A) | Larger footprint; better suited for higher-energy surges where board space allows | Select SMBJ13CA when surge energy exceeds 400 W or thermal dissipation requires lower RθJA |
| 1.5KE13CA | Through-hole DO-15 package; same VBR/VC; 1500 W PPPM, 102 A IPPM | Not SMT-compatible; intended for primary-side or chassis-level protection | Choose 1.5KE13CA only for legacy through-hole designs or where mechanical robustness outweighs SMT efficiency |
Compared with SMBJ13CA and 1.5KE13CA, the P4SMA13CAHE3/5A offers optimal balance of compact SMA footprint, AEC-Q101 qualification, and 400 W surge handling-making it preferred for space-constrained, automotive-grade SMT applications where full through-hole or larger SMD alternatives are impractical.

FAQ
What is the clamping voltage of P4SMA13CAHE3/5A at its rated peak pulse current?
The P4SMA13CAHE3/5A clamps to a maximum of 18.2 V at its rated peak pulse current of 22.0 A (10/1000 µs waveform). This value is measured under standardized test conditions and ensures downstream components experience limited overvoltage stress during transient events. The clamping voltage directly determines the protection margin for connected ICs or MOSFETs, and P4SMA13CAHE3/5A maintains this specification across its qualified temperature range.
Is P4SMA13CAHE3/5A suitable for automotive applications?
Yes, P4SMA13CAHE3/5A is AEC-Q101 qualified and specifically designated for automotive use via the "HE3" suffix. It has passed stress tests including high-temperature reverse bias, temperature cycling, and ESD per AEC-Q101 Rev D. Its 150 °C maximum junction temperature and bidirectional clamping make P4SMA13CAHE3/5A appropriate for engine control units, body control modules, and ADAS sensor interfaces where reliability under harsh conditions is mandatory.
What does the "CA" suffix indicate in P4SMA13CAHE3/5A?
The "CA" suffix in P4SMA13CAHE3/5A denotes a bidirectional configuration-meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., P4SMA13A), P4SMA13CAHE3/5A has no cathode band marking and functions identically regardless of polarity, simplifying layout for AC-coupled or floating signal paths. This is confirmed in Vishay's P4SMA datasheet section "DEVICES FOR BIDIRECTION APPLICATIONS".
What is the standoff voltage (VWM) of P4SMA13CAHE3/5A, and why does it matter?
The standoff voltage (VWM) of P4SMA13CAHE3/5A is 11.1 V-the maximum continuous reverse voltage it can block without exceeding 1.0 µA leakage current. This parameter ensures the device remains non-conductive during normal operation, avoiding power loss or signal distortion. Selecting a VWM ≥11.1 V prevents false triggering while maintaining sufficient margin below the 12.4 V minimum breakdown voltage, a critical design rule verified in the P4SMA13CAHE3/5A electrical characteristics table.
How does the SMA (DO-214AC) package of P4SMA13CAHE3/5A support automated manufacturing?
The SMA (DO-214AC) package of P4SMA13CAHE3/5A features a low-profile, symmetrical outline with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. Its MSL Level 1 rating permits exposure to peak reflow temperatures up to 260 °C without baking, and its bidirectional symmetry eliminates orientation verification during pick-and-place. These attributes make P4SMA13CAHE3/5A fully compatible with high-speed SMT lines used in automotive and industrial electronics production.
