Product details
Overview
P4SMA13AHE3_A/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 13 V breakdown voltage (VBR min/max: 12.4 V / 13.7 V), 11.1 V stand-off voltage (VWM), 18.2 V maximum clamping voltage at 22 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P4SMA13AHE3_A/I datasheet, P4SMA13AHE3_A/I pinout, P4SMA13AHE3_A/I application, or P4SMA13AHE3_A/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, low clamping voltage (18.2 V), thermal resistance (RθJA = 120 °C/W), and compatibility with automated SMT assembly on standard 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a voltage-clamping protection device that conducts above its breakdown threshold to shunt transient energy away from sensitive downstream circuitry. Its glass-passivated junction ensures stable leakage performance and fast response time (<1 ns), while the unidirectional configuration provides forward conduction path only during reverse overvoltage events.
The device is rated for 40 A non-repetitive forward surge current (IFSM) and supports continuous power dissipation of 3.3 W at 50 °C ambient on infinite heatsink. Junction temperature range spans −65 °C to +150 °C, and it meets MSL Level 1 per J-STD-020 with peak reflow temperature up to 260 °C.
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 clamping begins |
| VWM | 11.1 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 18.2 V at 22 A peak pulse current - clamping voltage seen by protected circuit during 10/1000 µs transient |
| PPPM | 400 W - peak transient power handling capability under standardized 10/1000 µs waveform |
| IFSM | 40 A - single half-sine surge current rating (8.3 ms), critical for inductive load switching protection |
| TJ max | +150 °C - maximum junction temperature enabling operation in under-hood automotive environments |
| RθJA | 120 °C/W - thermal resistance from junction to ambient, informs PCB copper pad sizing for thermal management |
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 marking; anode is unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Reverse voltage reference | Connected to lower-potential side (e.g., GND or return path); defines unidirectional conduction direction |
| Cathode | Clamping output / Surge current sink | Connected to protected line (e.g., 12 V rail or signal trace); conducts transient current to ground when VAK > VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per stress test plan |
| Glass passivated junction | Ensures stable reverse leakage (<1 µA at VWM) and long-term parameter stability across temperature and humidity |
| MSL Level 1 | Zero floor life limitation - can be stored indefinitely at ≤30 °C/60% RH without baking prior to reflow |
| 400 W peak pulse power | Handles high-energy transients such as ISO 7637-2 Pulse 1/2a/5a in 12 V automotive systems without degradation |
| Low clamping ratio (VC/VBR ≈ 1.4) | Minimizes overvoltage stress on protected ICs - e.g., keeps microcontroller I/O pins below absolute maximum ratings during load dump |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A | Same VBR (12.4–13.7 V), identical SMA package, but not AEC-Q101 qualified; RθJA = 130 °C/W vs. 120 °C/W | Approved for commercial/industrial use only; unsuitable for automotive under-hood deployment | Select when AEC-Q101 compliance is not required and cost sensitivity outweighs thermal margin needs. |
| 1.5SMC13A | Higher power rating (1500 W), larger SMC (DO-214AB) package, VBR = 12.4–13.7 V, VC = 21.2 V at 70.1 A | Used where higher surge immunity is needed (e.g., telecom power supplies), but requires larger PCB footprint and different layout | Choose when system-level surge testing exceeds IEC 61000-4-5 Level 4 and board space allows SMC footprint. |

FAQ
What is the breakdown voltage tolerance for P4SMA13AHE3_A/I?
The P4SMA13AHE3_A/I has a specified breakdown voltage range of 12.4 V to 13.7 V at 1.0 mA test current, representing ±5.4% tolerance around the nominal 13 V rating. This tight VBR window ensures consistent clamping behavior across production lots and supports predictable overvoltage protection design margins in automotive and industrial systems where P4SMA13AHE3_A/I is deployed.
Is P4SMA13AHE3_A/I suitable for bidirectional transient protection?
No, P4SMA13AHE3_A/I is a unidirectional TVS diode, identifiable by its cathode band marking and specified parameters (VBR, VWM, VC) for reverse-biased operation only. For bidirectional protection, Vishay offers the P4SMA13CA variant. Using P4SMA13AHE3_A/I in bidirectional configurations risks forward conduction during normal signal swings and invalidates its clamping performance claims.
Does P4SMA13AHE3_A/I meet automotive qualification standards?
Yes, P4SMA13AHE3_A/I is explicitly AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3" and documentation revision 09-Jan-2024 (Document Number: 88367). This qualification covers stress tests including temperature cycling, high-temperature reverse bias, and ESD, validating P4SMA13AHE3_A/I for under-hood and chassis-mounted automotive applications where reliability under thermal and electrical stress is mandatory.
What is the maximum clamping voltage of P4SMA13AHE3_A/I under surge conditions?
The maximum clamping voltage (VC) of P4SMA13AHE3_A/I is 18.2 V at 22 A peak pulse current with a 10/1000 µs waveform. This value is measured under standardized test conditions and represents the highest voltage imposed on the protected circuit during worst-case transient events - a critical parameter for ensuring downstream components like microcontrollers or gate drivers remain within their absolute maximum voltage ratings when P4SMA13AHE3_A/I is active.
How does the thermal resistance of P4SMA13AHE3_A/I affect PCB layout?
P4SMA13AHE3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W, measured on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To maintain junction temperature below 150 °C under 3.3 W steady-state dissipation, designers must allocate sufficient copper area and consider thermal vias - undersized pads will cause thermal derating and premature failure. This thermal profile directly informs layout decisions when integrating P4SMA13AHE3_A/I into high-reliability automotive or industrial boards.
