Product details
Overview
P4SMA13AHM3/I 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: 12.4–13.7 V at 1.0 mA), 11.1 V standoff voltage (VWM), 18.2 V maximum 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 P4SMA13AHM3/I datasheet, P4SMA13AHM3/I pinout, P4SMA13AHM3/I application, or P4SMA13AHM3/I equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 120 °C/W), polarity marking (cathode band), and halogen-free RoHS-compliant construction per JESD201 Class 2 whisker test.
Technical Context
This unidirectional TVS diode operates by avalanche breakdown to clamp transient overvoltages above its VWM of 11.1 V while maintaining low leakage (<1.0 µA). Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1.0 ns), enabling protection against ESD, inductive switching spikes, and lightning-induced surges.
The device is rated for 40 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine), supports operating junction temperatures from –65 °C to +150 °C, and meets MSL Level 1 per J-STD-020 with peak reflow temperature up to 260 °C - confirming suitability for automated SMT assembly without moisture sensitivity concerns.
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 threshold for reliable overvoltage triggering |
| VWM | 11.1 V - maximum continuous reverse working voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 18.2 V at 22.0 A - clamped voltage during 10/1000 µs transient, limiting stress on downstream components |
| PPPM | 400 W - peak pulse power handling capability under standardized surge waveform |
| RθJA | 120 °C/W - thermal resistance from junction to ambient, critical for derating power in PCB layout |
| TJ max | +150 °C - maximum junction temperature, supporting operation in under-hood automotive and industrial environments |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
Pinout & Package

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 RθJA (90 °C/W) | Higher power handling but larger footprint; less suitable for dense automotive PCBs | Select when higher surge margin is required and board space allows SMB footprint |
| 1.5SMC13A | Same VBR/VC specs, but SMC (DO-214AB) package; 1500 W PPPM, RθJA = 60 °C/W | Designed for high-energy industrial surges; requires larger copper pads and thermal relief | Choose for legacy designs using SMC or where IEC 61000-4-5 Level 5 compliance is mandatory |
Compared with SMBJ13A and 1.5SMC13A, the P4SMA13AHM3/I offers optimal balance of AEC-Q101 qualification, halogen-free compliance, compact SMA footprint, and 400 W surge capability - making it preferred for space-constrained automotive and industrial modules requiring production traceability and MSL-1 assembly compatibility.

FAQ
What is the breakdown voltage tolerance of P4SMA13AHM3/I?
The P4SMA13AHM3/I has a specified breakdown voltage (VBR) range of 12.4 V to 13.7 V at 1.0 mA test current, yielding ±5.4% tolerance around the nominal 13 V rating. This tight distribution ensures consistent clamping behavior across production lots and supports reliable design margining in safety-critical circuits.
Is P4SMA13AHM3/I suitable for automotive applications?
Yes, P4SMA13AHM3/I is AEC-Q101 qualified (indicated by the HM3 suffix) and tested for temperature cycling, high-temperature reverse bias, and ESD per automotive standards. Its -65 °C to +150 °C operating range and MSL Level 1 rating make it appropriate for under-hood and cabin ECU protection in passenger and commercial vehicles.
What does the "HM3" suffix mean in P4SMA13AHM3/I?
The "HM3" suffix in P4SMA13AHM3/I denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification and JESD201 Class 2 whisker resistance. It also specifies packaging in 13-inch tape-and-reel (I) format with 7500 units per reel - distinct from E3/M3 (commercial) or HE3/HM3 with 7-inch reels (H).
How does P4SMA13AHM3/I compare to bidirectional TVS diodes like P4SMA13CA?
P4SMA13AHM3/I is unidirectional and intended for DC-biased lines where polarity is fixed (e.g., 12 V supply rails), offering lower leakage and sharper knee characteristics. In contrast, P4SMA13CA is bidirectional and suited for AC or floating signals (e.g., data lines), but exhibits higher reverse leakage and symmetric clamping in both directions - not interchangeable without circuit review.
What is the maximum clamping voltage of P4SMA13AHM3/I under surge conditions?
The P4SMA13AHM3/I clamps to a maximum of 18.2 V at 22.0 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is guaranteed across temperature and lifetime, ensuring downstream ICs see no more than 18.2 V during transient events - critical for protecting 3.3 V or 5 V logic interfaces.
