Product details
Overview
P4SMA13AHM3_A/H 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 13 V breakdown voltage (VBR min/max: 12.4 V / 13.7 V), 11.1 V standoff voltage (VWM), 18.2 V clamping voltage (VC) at 22 A peak pulse current, and 400 W peak pulse power (10/1000 µs waveform), used to protect MOSFETs and ICs in automotive and industrial power supplies.
For engineers reviewing the P4SMA13AHM3_A/H datasheet, P4SMA13AHM3_A/H pinout, P4SMA13AHM3_A/H application, or P4SMA13AHM3_A/H 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 TVS diode operates as a unidirectional clamping device with glass-passivated junction and low incremental surge resistance, enabling fast response to transient overvoltage events induced by inductive load switching or ESD. Its 10/1000 µs waveform rating supports repetitive surge handling up to 0.01% duty cycle, with derating above 25 °C ambient per Fig. 2.
The device is rated for -65 °C to +150 °C operating junction temperature, meets MSL Level 1 per J-STD-020 (peak reflow 260 °C), and uses matte tin-plated leads solderable per J-STD-002 and JESD22-B102. Polarity is marked by a cathode band; no marking applies to bidirectional variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4 V / 13.7 V at 1.0 mA test current - defines precise voltage threshold where avalanche conduction begins reliably |
| VWM | 11.1 V - maximum continuous reverse working voltage before leakage exceeds 1.0 µA, ensuring safe operation under normal bias |
| VC @ IPPM | 18.2 V at 22 A peak pulse current - clamped voltage during 400 W transient, limiting stress on downstream components |
| PPPM | 400 W (10/1000 µs waveform) - peak surge power handling capability, critical for automotive load-dump and ISO 7637-2 compliance |
| IFSM | 40 A (8.3 ms half-sine) - forward surge current rating, supporting robustness against short-duration inrush or fault currents |
| RθJA | 120 °C/W - junction-to-ambient thermal resistance on standard 0.2" × 0.2" copper pads, guiding PCB thermal layout requirements |
| TJ max | +150 °C - maximum junction temperature, enabling use in under-hood automotive environments and high-temperature industrial enclosures |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile case with matte tin-plated leads; cathode identified by a visible band on the body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / transient return path | Connected to ground or low-impedance return in unidirectional configuration; must be routed with minimal inductance for effective clamping |
| Cathode | Transient voltage sensing / clamping node | Connected to protected line (e.g., 12 V rail); cathode band marks this terminal - incorrect orientation disables protection |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - required for engine control, body electronics, and ADAS modules |
| Halogen-free & RoHS-compliant | Meets JEDEC J-STD-609A Class 1 definition and EU RoHS Directive 2011/65/EU - supports green manufacturing and end-of-life compliance |
| MSL Level 1 | Rated for peak reflow temperatures up to 260 °C without preconditioning - eliminates moisture sensitivity concerns during SMT assembly |
| 400 W peak pulse power | Handles ISO 7637-2 Pulse 1 (inductive switch-off) and Pulse 2a (load dump simulation) without degradation when mounted per recommended pad layout |
| Glass passivated junction | Provides stable VBR tolerance and low leakage (<1 µA at VWM) across temperature and lifetime - ensures consistent protection margin |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Guarding |
|---|---|
Use Scenario: Protecting 12 V supply rails in engine control units (ECUs) against load-dump transients up to 40 V and inductive kickback from solenoids or relays. IC Role / Device Role / Timing Role: Unidirectional TVS clamping element placed between battery input and DC/DC converter input stage. Use Value: Limits voltage to ≤18.2 V during 400 W surges, preventing damage to LDOs and microcontrollers while maintaining AEC-Q101 compliance. |

Use Scenario: Safeguarding primary-side rectifier and controller ICs in telecom power supplies exposed to lightning-induced surges on -48 V DC distribution lines. IC Role / Device Role / Timing Role: First-line transient suppressor upstream of bulk capacitor and PWM controller, sized for 10/1000 µs waveform energy absorption. Use Value: Absorbs 400 W pulses without thermal runaway (RθJA = 120 °C/W), enabling compact board layout without heatsinking. |
Use Scenario: Preventing ESD damage to USB data lines and VBUS pins in portable audio devices during hot-plug and human-body-model (HBM) events. IC Role / Device Role / Timing Role: Unidirectional clamp on VBUS line only (not data lines), coordinated with dedicated ESD arrays on D+/D-. Use Value: Provides 11.1 V working voltage margin above 5 V nominal, with 18.2 V clamping to keep downstream USB switch ICs within absolute maximum ratings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A-E3/5A | Same VBR (12.4–13.7 V), identical SMA package, but rated for 400 W with 1.5 kW peak pulse power capability per 10/1000 µs; RθJA = 110 °C/W | Higher surge margin suits harsher ISO 16750-2 environments; slightly tighter VBR tolerance (5%) vs. P4SMA13AHM3_A/H (10%) | Select SMAJ13A-E3/5A when higher single-pulse robustness or tighter breakdown consistency is required, especially in safety-critical subsystems. |
| 1.5SMC13A | Same VBR/VC specs but in larger SMC (DO-214AB) package; 1.5 kW peak pulse power; RθJA = 70 °C/W; not AEC-Q101 qualified | Lower thermal resistance enables higher average power handling; lacks automotive qualification and halogen-free certification | Choose 1.5SMC13A for non-automotive industrial applications needing extended surge endurance and better thermal performance, accepting larger footprint. |
Compared with SMAJ13A-E3/5A and 1.5SMC13A, P4SMA13AHM3_A/H offers AEC-Q101 qualification, halogen-free construction, and MSL Level 1 compatibility in the smallest SMA footprint - making it optimal for space-constrained automotive modules where regulatory compliance and assembly reliability are mandatory.

FAQ
What is the breakdown voltage range for P4SMA13AHM3_A/H?
The P4SMA13AHM3_A/H has a guaranteed breakdown voltage (VBR) range of 12.4 V to 13.7 V at 1.0 mA test current, measured per ANSI/IEEE C62.35. This tight 10% tolerance ensures predictable clamping onset in automotive and industrial circuits where precise overvoltage thresholds are critical for system-level protection coordination.
Is P4SMA13AHM3_A/H qualified for automotive applications?
Yes, P4SMA13AHM3_A/H is AEC-Q101 qualified - confirmed by Vishay's documentation (Revision 09-Jan-2024, Doc. #88367). The "HM3" suffix denotes halogen-free, RoHS-compliant construction with JESD201 Class 2 whisker resistance, and the "_A/H" revision code indicates full automotive qualification per the P4SMA series roadmap for 6.8 V to 220 V devices.
What does the "HM3" suffix mean in P4SMA13AHM3_A/H?
In P4SMA13AHM3_A/H, "HM3" specifies halogen-free, RoHS-compliant construction meeting JEDEC J-STD-609A Class 1, with matte tin-plated leads qualified per JESD22-B102 and J-STD-002. It also confirms compliance with JESD201 Class 2 whisker testing - a requirement for automotive and high-reliability industrial deployments.
What is the clamping voltage of P4SMA13AHM3_A/H at its rated peak pulse current?
The P4SMA13AHM3_A/H clamps to a maximum of 18.2 V at its rated peak pulse current (IPPM) of 22 A, tested with a 10/1000 µs waveform. This value is measured under standardized conditions (TA = 25 °C, mounted on 0.2" × 0.2" copper pads) and defines the upper voltage limit imposed on protected circuitry during surge events.
Does P4SMA13AHM3_A/H have polarity marking, and how is it oriented?
Yes, P4SMA13AHM3_A/H is unidirectional and features a visible cathode band on the SMA (DO-214AC) package body. The banded end is the cathode and must be connected to the line being protected (e.g., 12 V rail), while the anode connects to ground. Incorrect orientation renders the device non-functional as a transient suppressor.
