Product details
Overview
P4SMA22AHE3/61 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 22 V breakdown voltage (VBR = 20.9–23.1 V at IT = 1.0 mA), 18.8 V standoff voltage (VWM), 30.6 V maximum clamping voltage (VC) at 13.1 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 automotive and industrial electronics.
For engineers reviewing the P4SMA22AHE3/61 datasheet, P4SMA22AHE3/61 pinout, P4SMA22AHE3/61 application, or P4SMA22AHE3/61 equivalent, key selection criteria include its AEC-Q101 qualification, unidirectional polarity with cathode band marking, low incremental surge resistance, fast response time, and compatibility with automated SMT placement on standard PCB copper pads.
Technical Context
The P4SMA22AHE3/61 operates as a silicon avalanche diode that enters breakdown when reverse voltage exceeds VBR, diverting transient energy to ground while limiting downstream voltage to ≤30.6 V. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and robust surge handling up to 40 A IFSM (8.3 ms half-sine).
Thermally, it exhibits RθJA = 120 °C/W and RθJL = 30 °C/W, enabling reliable operation up to TJ = +150 °C. The device is rated for MSL Level 1 per J-STD-020 and qualified to AEC-Q101 for automotive under-hood and body-control applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 20.9–23.1 V at 1.0 mA test current - defines precise avalanche initiation threshold for repeatable clamping behavior |
| Standoff Voltage VWM | 18.8 V - maximum continuous reverse operating voltage before significant leakage begins |
| Clamping Voltage VC | 30.6 V at 13.1 A IPPM (10/1000 µs) - limits protected circuit voltage during surge events |
| Peak Pulse Power PPPM | 400 W - sustains single transient surges without degradation when mounted on 5.0 mm × 5.0 mm copper pads |
| Reverse Leakage ID | <1.0 µA at VWM - ensures minimal standby power loss and signal integrity in high-impedance circuits |
| Operating Temperature | −65 °C to +150 °C - supports under-hood automotive and wide-temperature industrial environments |
| AEC-Q101 Qualified | Yes - validated for automotive reliability including temperature cycling, HTRB, and ESD testing per AEC standard |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile plastic case with matte tin-plated leads solderable per J-STD-002. Cathode indicated by a band on the body; anode is unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to ground or low-impedance return path to shunt surge current away from protected IC or MOSFET |
| Anode (unbanded end) | Protected line input | Connected to power rail or signal line requiring overvoltage protection; reverse-biased during normal operation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress - suitable for body control modules and ADAS sensors |
| Glass-passivated junction | Ensures stable VBR tolerance and low leakage across temperature and lifetime - critical for long-term protection integrity |
| MSL Level 1 rating | Compatible with standard reflow profiles up to 260 °C peak - eliminates moisture sensitivity concerns during assembly |
| 400 W peak pulse power | Handles IEC 61000-4-5 surge waveforms (10/1000 µs) without failure when properly mounted - protects against lightning-induced and inductive-switching transients |
| Low clamping ratio (VC/VBR ≈ 1.32) | Minimizes overvoltage exposure to downstream components - improves margin for 24 V automotive systems and 3.3/5 V logic interfaces |
Applications
| Automotive Body Control Module | Industrial PLC 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 |
|---|---|---|---|
| SMAJ22A-E3/5A | Same VBR range (20.9–23.1 V), identical SMA package, but rated for 400 W only at TA ≤ 25 °C; no AEC-Q101 qualification | Commercial-grade use only; not approved for automotive production | Select P4SMA22AHE3/61 when AEC-Q101 compliance and extended temperature validation are required. |
| 1.5SMC22A | Higher package thermal resistance (RθJA ≈ 150 °C/W vs. 120 °C/W); same VBR and VC, but larger SMC (DO-214AB) footprint | Requires PCB layout change; less suitable for space-constrained automotive modules | Choose P4SMA22AHE3/61 for compact layouts and superior thermal performance in dense SMT assemblies. |
Compared with SMAJ22A-E3/5A and 1.5SMC22A, the P4SMA22AHE3/61 delivers verified automotive qualification, tighter thermal resistance, and optimized pad layout compatibility - making it the preferred choice for production-grade automotive and industrial designs where reliability and board space are critical.

FAQ
What is the clamping voltage of P4SMA22AHE3/61 at its rated peak pulse current?
The P4SMA22AHE3/61 has a maximum clamping voltage (VC) of 30.6 V at 13.1 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured with the device mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per JEDEC standards and reflects worst-case voltage seen by protected circuitry during surge events.
Is P4SMA22AHE3/61 suitable for bidirectional signal line protection?
No, P4SMA22AHE3/61 is a unidirectional TVS diode - it conducts only in reverse bias and requires correct polarity orientation (cathode to ground). For bidirectional protection, Vishay offers the P4SMA22CA variant. Using P4SMA22AHE3/61 on AC or dual-polarity lines risks forward conduction and failure.
Does P4SMA22AHE3/61 meet automotive qualification standards?
Yes, P4SMA22AHE3/61 is AEC-Q101 qualified and carries the HE3 suffix denoting RoHS-compliant and automotive-grade construction. It undergoes stress testing per AEC-Q101 including HTGB, HTRB, temperature cycling, and ESD - making it suitable for production automotive applications such as body control modules and ADAS sensor interfaces.
What is the standoff voltage rating of P4SMA22AHE3/61, and how does it relate to system operating voltage?
The standoff voltage (VWM) of P4SMA22AHE3/61 is 18.8 V - the maximum DC or RMS voltage the device can block continuously without significant leakage. For reliable operation, system nominal voltage (e.g., 12 V or 24 V automotive rails) must remain below this value; it is commonly used on 12 V systems with margin for ripple and transients.
Can P4SMA22AHE3/61 be used in place of P4SMA22A-E3/61?
Yes, P4SMA22AHE3/61 is the AEC-Q101 qualified version of P4SMA22A-E3/61, sharing identical electrical parameters, package, and pinout. The HE3 suffix adds automotive qualification and enhanced process controls - it is a drop-in replacement where automotive reliability is required, with no PCB or schematic changes needed.
