Product details
Overview
P4SMA15AHE3/61 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P4SMA series, designed for clamping voltage transients on power and signal lines. It features a 15 V breakdown voltage (VBR = 14.3–15.8 V at 1 mA), 12.8 V standoff voltage (VWM), 21.2 V maximum clamping voltage (VC) at 18.9 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform - suitable for protecting MOSFETs, ICs, and sensor signal lines in automotive and industrial control systems.
For engineers reviewing the P4SMA15AHE3/61 datasheet, P4SMA15AHE3/61 pinout, P4SMA15AHE3/61 application, or P4SMA15AHE3/61 equivalent, this device delivers AEC-Q101 qualification, low incremental surge resistance, fast response time, and MSL Level 1 moisture sensitivity - critical for high-reliability automotive electronics and board-level ESD/surge protection design.
Technical Context
The P4SMA15AHE3/61 operates as a unidirectional avalanche diode, leveraging glass-passivated junction technology to achieve precise breakdown behavior and stable clamping under transient stress. Its cathode-band polarity marking enables unambiguous PCB orientation during automated placement.
Designed for surface-mount use in SMA (DO-214AC) package, it supports 40 A non-repetitive forward surge current (IFSM) and maintains operation across -65 °C to +150 °C junction temperature range. Thermal resistance is 120 °C/W (junction-to-ambient) and 30 °C/W (junction-to-lead), requiring minimal copper pad area (0.2" × 0.2") for rated 400 W pulse handling.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A-E3/61 | Same SMA package, identical VBR (14.3–15.8 V), but rated for 400 W only up to 91 V; no AEC-Q101 qualification | Commercial-grade only; not approved for automotive production | Select P4SMA15AHE3/61 when AEC-Q101 compliance and extended surge margin are required |
| 1.5SMC15A | Larger SMC (DO-214AB) package, same electrical specs, higher thermal mass (RθJA = 100 °C/W), 1000 W peak rating | Used where board space allows larger footprint and higher energy absorption is needed | Choose P4SMA15AHE3/61 for space-constrained automotive PCBs requiring AEC-Q101 and low-profile mounting |
Compared with SMAJ15A-E3/61 and 1.5SMC15A, the P4SMA15AHE3/61 uniquely combines AEC-Q101 qualification, DO-214AC footprint, and 400 W surge capability - making it the preferred choice for automotive body electronics and industrial controllers where reliability, size, and qualification converge.

FAQ
What is the clamping voltage of P4SMA15AHE3/61 under a 10/1000 µs surge?
The P4SMA15AHE3/61 exhibits a maximum clamping voltage (VC) of 21.2 V when subjected to its rated peak pulse current of 18.9 A using the standard 10/1000 µs waveform. This value is measured per Figure 1 in Vishay document 88367 and ensures downstream components experience limited overvoltage during transient events. The P4SMA15AHE3/61 maintains this clamping performance across its specified operating temperature range.
Is P4SMA15AHE3/61 qualified for automotive applications?
Yes, P4SMA15AHE3/61 is AEC-Q101 qualified, as confirmed in the Vishay P4SMA datasheet revision 09-Jan-2024. The "HE3" suffix denotes RoHS-compliant and AEC-Q101 qualified construction, validated for temperature cycling, highly accelerated life testing (HALT), and ESD robustness. This makes P4SMA15AHE3/61 suitable for under-hood and cabin electronics where automotive reliability standards apply.
What is the standoff voltage (VWM) of P4SMA15AHE3/61, and why does it matter?
The standoff voltage (VWM) of P4SMA15AHE3/61 is 12.8 V - the maximum continuous reverse voltage the device can block without exceeding 1 µA leakage current. This parameter ensures the P4SMA15AHE3/61 remains non-conductive during normal operation of a 12 V automotive or industrial system, avoiding power loss or false triggering while still responding instantly to transients exceeding 14.3 V breakdown.
Does P4SMA15AHE3/61 have a bidirectional variant?
No, P4SMA15AHE3/61 is strictly unidirectional. Bidirectional variants in the P4SMA family use the "CA" suffix (e.g., P4SMA15CA). The "A" in P4SMA15AHE3/61 explicitly indicates unidirectional configuration, with cathode marked by a band. Using a unidirectional part like P4SMA15AHE3/61 in AC-coupled or symmetrical signal paths requires careful circuit topology review to avoid forward conduction issues.
What package type does P4SMA15AHE3/61 use, and what are its key mechanical features?
P4SMA15AHE3/61 uses the SMA (DO-214AC) surface-mount package: low-profile, 2-terminal, with dimensions of 4.50 mm × 2.79 mm × 2.29 mm (L × W × H). Key features include UL 94 V-0 compliant molding compound, matte tin-plated leads compatible with J-STD-002 soldering, and MSL Level 1 rating for 260 °C peak reflow. The cathode band provides clear polarity identification for automated placement of P4SMA15AHE3/61.
