Product details
Overview
P4SMA13AHE3_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 a 13 V breakdown voltage (VBR = 12.4–13.7 V at 1 mA), 11.1 V standoff 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 electronics.
For engineers reviewing the P4SMA13AHE3_A/H datasheet, P4SMA13AHE3_A/H pinout, P4SMA13AHE3_A/H application, or P4SMA13AHE3_A/H equivalent, key selection criteria include clamping voltage margin vs. protected device VDS/VCC, thermal derating above 25 °C, AEC-Q101 qualification status, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
The P4SMA13AHE3_A/H operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low incremental surge resistance, enabling fast response (<1 ns) to ESD and lightning-induced transients.
It is rated for 400 W peak pulse power (10/1000 µs) at 25 °C, derated linearly above TA = 25 °C per Fig. 2, with thermal resistance RθJA = 120 °C/W and RθJL = 30 °C/W. The device meets MSL Level 1 and is AEC-Q101 qualified for automotive applications.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A-E3/52 | Higher package thermal resistance (RθJA = 140 °C/W), same VBR and PPPM, SMB (DO-214AA) footprint | Larger footprint requires PCB redesign; lower power density limits high-repetition-rate use | Select when existing SMB layout exists and AEC-Q101 is not required |
| 1.5KE13A | Through-hole TO-204AA (DO-41), 1500 W rating but slower response and no AEC-Q101 qualification | Not suitable for automated SMT production or automotive under-hood mounting | Choose only for legacy through-hole designs where board space and qualification are secondary |
Compared with SMBJ13A-E3/52 and 1.5KE13A, the P4SMA13AHE3_A/H delivers superior SMT manufacturability, AEC-Q101 compliance, and thermal performance in compact SMA packaging - making it optimal for new automotive and high-density industrial designs.

FAQ
What is the breakdown voltage tolerance of the P4SMA13AHE3_A/H?
The P4SMA13AHE3_A/H has a specified breakdown voltage range of 12.4 V to 13.7 V at test current IT = 1 mA, corresponding to a ±5% tolerance around the nominal 13 V rating. This tight VBR distribution ensures consistent clamping behavior across production lots and supports predictable circuit protection design for the P4SMA13AHE3_A/H.
Is the P4SMA13AHE3_A/H suitable for automotive applications?
Yes, the P4SMA13AHE3_A/H is AEC-Q101 qualified and explicitly designated for automotive use via the "HE3" suffix and revision "_A/H". It undergoes stress testing for temperature cycling, high-temperature reverse bias, and ESD per AEC-Q101 requirements - confirming its suitability for engine control units, body electronics, and ADAS modules where the P4SMA13AHE3_A/H provides certified transient protection.
What is the maximum clamping voltage of the P4SMA13AHE3_A/H at rated peak pulse current?
The P4SMA13AHE3_A/H exhibits a maximum clamping voltage VC of 18.2 V at its rated peak pulse current IPPM = 22 A (10/1000 µs waveform). This value is guaranteed per datasheet Table "ELECTRICAL CHARACTERISTICS" and defines the upper voltage limit imposed on protected circuitry during transient events - a critical parameter for ensuring the P4SMA13AHE3_A/H does not overstress downstream ICs or MOSFETs.
Does the P4SMA13AHE3_A/H have a bidirectional variant?
No, the P4SMA13AHE3_A/H is strictly unidirectional, as indicated by the "A" suffix and absence of "CA" in the part number. Bidirectional variants exist in the same family (e.g., P4SMA13CA), but they differ in construction, marking, and electrical symmetry - the P4SMA13AHE3_A/H must be used only in polarity-aware configurations with cathode connected to the protected line.
What is the thermal resistance of the P4SMA13AHE3_A/H and how does it affect power derating?
The P4SMA13AHE3_A/H has a typical junction-to-ambient thermal resistance RθJA of 120 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads. This value directly determines power derating: above 25 °C ambient, the 3.3 W steady-state power dissipation must be reduced linearly per Figure 2 in the datasheet - a key constraint for sustained operation of the P4SMA13AHE3_A/H in enclosed or high-temperature environments.
