Product details
Overview
P4KA13AHE3/73 from Vishay General Semiconductor is a unidirectional automotive-grade transient voltage suppressor (TVS) diode in DO-204AL (DO-41) package, featuring 12.4 V to 13.7 V breakdown voltage (VBR), 400 W peak pulse power (10/1000 µs), 18.2 V clamping voltage at 22.0 A surge current, and AEC-Q101 qualification for under-hood electronics protection.
For engineers reviewing the P4KA13AHE3/73 datasheet, P4KA13AHE3/73 pinout, P4KA13AHE3/73 application, or P4KA13AHE3/73 equivalent, key selection criteria include clamping performance at 22 A, unidirectional polarity with cathode band marking, high-temperature operation up to +185 °C junction, and RoHS-compliant matte tin-plated leads meeting J-STD-002 solderability.
Technical Context
This TVS diode uses patented PAR® construction to deliver low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of inductive switching transients and ESD events in automotive power rails and sensor signal lines. Its 10/1000 µs waveform rating aligns with ISO 7637-2 and SAE J1113-11 standards for vehicle-level surge immunity.
The device operates as a voltage-clamping component placed in parallel with protected circuitry, conducting only when reverse voltage exceeds VBR. Its 0.081 %/°C temperature coefficient ensures stable breakdown across -65 °C to +185 °C, critical for engine control units and ADAS modules exposed to thermal cycling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4 V / 13.7 V - Ensures reliable turn-on above system nominal voltage while avoiding false triggering during load dump or cold-crank conditions. |
| VC @ IPPM | 18.2 V at 22.0 A - Limits maximum voltage seen by downstream ICs during 400 W transient events, protecting 12 V logic interfaces and MOSFET gates. |
| PPPM | 400 W (10/1000 µs) - Withstands repetitive automotive load-dump surges without degradation when operated within duty cycle limits (0.01 %). |
| TJ max. | +185 °C - Supports placement near high-heat sources such as power converters or engine compartments without derating loss. |
| VWM | 11.1 V - Provides sufficient margin below VBR to prevent leakage-induced power loss in always-on 12 V circuits. |
| IFSM | 40 A (8.3 ms half-sine) - Handles short-duration battery-reversal or jump-start fault currents without bond-wire fusing. |
Pinout & Package
Package: DO-204AL (DO-41), axial leaded, molded epoxy case with UL 94 V-0 rating. Cathode indicated by color band on body end.
| Pin/Terminal | Circuit Role | Design Meaning |

Key Features
| Feature | Design Value |
|---|---|

| AEC-Q101 qualified | Validated for automotive applications including engine control, body electronics, and infotainment with zero defects in stress testing. |
| Matte tin plated leads | Ensures robust solder joint formation per J-STD-002 and passes JESD22-B102 wetting tests for high-reliability assembly. |
| RoHS & WEEE compliant | Meets EU Directive 2002/95/EC and 2002/96/EC requirements for hazardous substance restriction and end-of-life recycling. |
Applications
| Engine Control Unit (ECU) Power Rail Protection | Automotive Sensor Signal Line Protection |
|---|---|
Use Scenario: Suppresses load-dump transients (up to 60 V, 400 ms) induced by alternator disconnection in 12 V power distribution networks feeding ECUs. IC Role / Device Role / Timing Role: Voltage-clamping TVS placed between battery rail and ECU input filter capacitor.

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-E3/57T | Same VBR range (12.4–13.7 V), but SMA package (surface-mount); 400 W rating, 18.2 V VC, but lower IFSM (30 A vs. 40 A). | Requires PCB rework for SMT layout; unsuitable for through-hole legacy designs or high-vibration environments where axial leads provide mechanical retention. | Select when board space is constrained and automated assembly is used; verify mechanical anchoring for under-hood vibration. |
| 1N6114A | Same DO-41 package and unidirectional polarity, but lower PPPM (300 W), higher VC (20.0 V), and no AEC-Q101 qualification. | Lacks automotive reliability validation; not recommended for safety-critical or high-temperature under-hood use. | Acceptable for cost-sensitive industrial or consumer applications where 400 W surge immunity and +185 °C operation are not required. |
Compared with SMAJ13A-E3/57T and 1N6114A, the P4KA13AHE3/73 provides superior mechanical robustness via axial leads, guaranteed AEC-Q101 compliance, and higher surge current handling-making it the preferred choice for production automotive electronics requiring long-term field reliability.

FAQ
What is the breakdown voltage tolerance of the P4KA13AHE3/73?
The P4KA13AHE3/73 has a specified breakdown voltage range of 12.4 V to 13.7 V at 1.0 mA test current, corresponding to ±5.4 % tolerance around the nominal 13.05 V midpoint. This tight VBR window ensures consistent clamping behavior across production lots and supports precise overvoltage threshold design in automotive power management circuits.
Is the P4KA13AHE3/73 suitable for bidirectional transient protection?
No, the P4KA13AHE3/73 is unidirectional only, with cathode marked by a color band. It protects against positive-going transients on a line referenced to ground. For bidirectional protection (e.g., data lines with AC signals), a separate bidirectional TVS such as the SMBJ13CA must be selected-P4KA13AHE3/73 does not conduct in forward bias beyond its 3.5 V forward voltage limit.
Does the P4KA13AHE3/73 require heatsinking for continuous power dissipation?
The P4KA13AHE3/73 has a steady-state power dissipation rating of 1.5 W on an infinite heatsink at 75 °C lead temperature. In typical automotive PCB mounting without added heatsink, its thermal resistance (RθJA) limits continuous dissipation to ~0.5 W. It is intended for transient-only operation-not sustained DC power handling-so no external heatsink is needed for its rated 400 W pulse applications.
How does the P4KA13AHE3/73 perform at elevated junction temperatures?
The P4KA13AHE3/73 maintains full 400 W pulse capability up to +125 °C junction temperature, with linear derating to ~250 W at +185 °C per Figure 2 in the datasheet. Its 0.081 %/°C VBR temperature coefficient ensures predictable clamping voltage shift across the full operating range, critical for thermal stability in under-hood deployments.
What is the meaning of the "HE3/73" suffix in P4KA13AHE3/73?
The "HE3" suffix indicates RoHS-compliant, high-reliability automotive grade per JESD201 Class 2 whisker resistance, while "/73" denotes packaging in 73 mm tape-and-reel format (5500 pcs/reel). This distinguishes P4KA13AHE3/73 from other variants like P4KA13AHE3/54 (54 mm reel) and confirms compliance with AEC-Q101 and lead-free assembly requirements.
