Product details
Overview
P4SMA13A-E3/5A from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping voltage transients on power and signal 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), 18.2 V clamping voltage (VC) at 22.0 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor signal lines in industrial and automotive electronics.
For engineers reviewing the P4SMA13A-E3/5A datasheet, P4SMA13A-E3/5A pinout, P4SMA13A-E3/5A application, or P4SMA13A-E3/5A equivalent, key selection criteria include unidirectional polarity, 1.0 µA max reverse leakage at VWM, -65 °C to +150 °C operating junction temperature, RoHS-compliant matte tin-plated leads, and MSL Level 1 moisture sensitivity per J-STD-020.
Technical Context
The P4SMA13A-E3/5A operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5% typical), low incremental surge resistance, and fast response time (<1 ns) to transient events such as ESD, inductive switching spikes, and lightning-induced surges.
It is rated for 400 W peak pulse power (10/1000 µs) at TA = 25 °C, derating linearly above 25 °C with RθJA = 120 °C/W. The device meets AEC-Q101 qualification when ordered with HE3/HM3 suffixes, but P4SMA13A-E3/5A is commercial-grade RoHS-compliant with no AEC-Q101 marking.
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 reliable overvoltage triggering |
| VWM | 11.1 V - maximum continuous reverse operating voltage before leakage rises significantly |
| VC @ IPPM | 18.2 V at 22.0 A - clamped voltage during 10/1000 µs transient, limiting stress on downstream components |
| IPPM | 22.0 A - peak pulse current capability under standardized surge waveform |
| PPPM | 400 W - transient energy absorption capacity without failure, critical for surge immunity design |
| ID @ VWM | 1.0 µA - ultra-low reverse leakage preserves signal integrity and minimizes standby power loss |
| TJ Range | -65 °C to +150 °C - wide thermal operating envelope supports under-hood and industrial environments |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile plastic case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Cathode indicated by band; anode is unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connects to protected line; conducts surge current to ground when VREV > VBR |
| Anode (unbanded end) | Reference/return path | Typically tied to system ground or lower-potential rail; completes clamping path |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures stable, repeatable breakdown voltage and long-term reliability under repeated surge stress |
| 400 W peak pulse power (10/1000 µs) | Supports robust protection against IEC 61000-4-5 Level 3/4 surges in industrial power rails |
| MSL Level 1 (260 °C peak reflow) | Enables standard SMT assembly without moisture-related popcorning or delamination |
| Low profile SMA package | Reduces board space vs. DO-15/DO-201; compatible with automated pick-and-place equipment |
| RoHS-compliant, halogen-free option available | Meets environmental compliance requirements for consumer, telecom, and automotive supply chains |
Applications
| Industrial Motor Control | Automotive Sensor Interface |
|---|---|
Use Scenario: Protecting gate drivers and logic inputs from inductive kickback in 24 V DC motor controllers. IC Role / Device Role / Timing Role: Unidirectional TVS placed across MOSFET gate-source or between microcontroller I/O and external sensor wiring.

IC Role / Device Role / Timing Role: Standoff-rated protection on signal lines upstream of ESD diodes or integrated receivers. Use Value: 11.1 V VWM allows compatibility with 12 V nominal systems; 1.0 µA leakage avoids bias errors in precision analog front-ends. |

Use Scenario: Secondary overvoltage protection on VBUS lines of USB 2.0/3.0 ports in laptops and docking stations. IC Role / Device Role / Timing Role: Back-to-back or single-diode clamp between VBUS and GND, supplementing internal port controller protection. Use Value: Fast <1 ns response captures fast-rising ESD events; SMA footprint enables compact layout adjacent to USB connector. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A | 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; requires larger PCB pad area and different reflow profile due to higher thermal mass | Select SMBJ13A when surge energy exceeds 400 W or when existing layout accommodates SMB footprint |
| 1.5SMC13A | Same VBR/VC specs, but SMC (DO-214AB) package; 1500 W PPPM, 120 A IPPM, 3× larger size and thermal resistance | Designed for primary-side AC line or high-power DC bus protection; not suitable for space-constrained signal-line use | Choose 1.5SMC13A only for high-power industrial mains interfaces where PCB real estate and thermal budget allow |
Compared with SMBJ13A and 1.5SMC13A, the P4SMA13A-E3/5A delivers optimal balance of surge robustness (400 W), compact SMA footprint, and low-leakage performance for secondary-side and signal-line protection - making it preferred for dense, cost-sensitive, and thermally constrained designs.

FAQ
What is the polarity configuration of the P4SMA13A-E3/5A?
The P4SMA13A-E3/5A is a unidirectional TVS diode, meaning it conducts only in reverse bias above its breakdown voltage. The cathode is marked by a band on the SMA package body; the anode is the unmarked end. This configuration makes P4SMA13A-E3/5A suitable for DC line protection where polarity is fixed, unlike bidirectional variants (e.g., P4SMA13CA) used in AC or differential signal paths.
Does the P4SMA13A-E3/5A meet AEC-Q101 qualification?
No, the P4SMA13A-E3/5A is a commercial-grade RoHS-compliant part with E3 suffix and 5A tape-and-reel packaging. AEC-Q101 qualification requires the HE3 or HM3 suffix (e.g., P4SMA13AHE3_A). While P4SMA13A-E3/5A shares identical electrical specs and construction, it lacks the extended test validation required for automotive under-hood use. For AEC-Q101 applications, specify P4SMA13AHE3_A instead of P4SMA13A-E3/5A.
What is the maximum clamping voltage of the P4SMA13A-E3/5A under surge conditions?
The P4SMA13A-E3/5A has a maximum clamping voltage (VC) of 18.2 V at 22.0 A peak pulse current (IPPM) using the standard 10/1000 µs waveform. This value is guaranteed per datasheet Table on page 2 and represents the upper limit of voltage seen by protected circuitry during a defined transient event - critical for ensuring downstream ICs remain within absolute maximum ratings.
Can the P4SMA13A-E3/5A be used in bidirectional signal protection?
No, the P4SMA13A-E3/5A is strictly unidirectional and must not be used on AC-coupled or differential lines without additional circuitry. For bidirectional protection, Vishay specifies the CA-suffixed variant (e.g., P4SMA13CA), which exhibits symmetrical clamping in both directions. Using P4SMA13A-E3/5A in place of a bidirectional device risks forward conduction and failure during negative transients.
What is the thermal resistance and derating behavior of the P4SMA13A-E3/5A?
The P4SMA13A-E3/5A has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on minimum recommended copper pads (0.2" × 0.2"). Its peak pulse power rating derates linearly above 25 °C ambient, dropping to ~240 W at 75 °C and ~120 W at 125 °C per Figure 2 in the datasheet. This derating must be applied in thermally dense layouts or high-temperature enclosures to avoid thermal runaway during repetitive surges.
