Product details
Overview
P6KA15HE3/73 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for primary overvoltage protection of DC power rails and signal lines in automotive and industrial systems. It features a 15 V breakdown voltage (VBR = 13.5–16.3 V), 600 W peak pulse power (10/1000 μs), 22.0 V maximum clamping voltage at 27.3 A, and AEC-Q101 qualification for under-hood applications.
For engineers reviewing the P6KA15HE3/73 datasheet, P6KA15HE3/73 pinout, P6KA15HE3/73 application, or P6KA15HE3/73 equivalent, this page delivers verified electrical parameters, DO-204AC package details, clamping behavior under surge conditions, and validated alternatives for automotive-grade circuit protection design.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to achieve stable junction performance up to TJ = 185 °C, enabling reliable operation in high-temperature environments such as engine control units and powertrain modules. Its unidirectional polarity and low incremental surge resistance ensure fast response (<1 ns) and minimal voltage overshoot during ESD or load-dump transients.
The device complies with ANSI/IEEE C62.35 for transient suppression and is rated for repetitive 10/1000 μs surges at 0.01 % duty cycle. Clamping voltage is specified at IPPM = 27.3 A, with VC ≤ 22.0 V - a critical parameter for safeguarding 12 V automotive electronics against ISO 7637-2 Pulse 1 and Pulse 2b events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 13.5 V / 16.3 V - defines precise breakdown threshold for predictable turn-on during overvoltage events |
| VWM | 12.1 V - maximum continuous reverse operating voltage; ensures no leakage conduction during normal 12 V rail operation |
| VC @ IPPM | 22.0 V at 27.3 A - clamping voltage limits downstream IC stress below safe semiconductor thresholds |
| PPPM | 600 W - peak pulse power handling capability for 10/1000 μs waveform per IEC 61000-4-5 |
| IFSM | 75 A - surge current rating for 8.3 ms half-sine wave, supporting load-dump immunity |
| TJ max. | 185 °C - enables placement near heat sources without derating loss in protection margin |
| AEC-Q101 | Qualified - certified for automotive electronic components per stress test requirements |
Pinout & Package
Package: DO-204AC (DO-15), molded epoxy case with matte tin-plated leads; cathode indicated by color band; RoHS-compliant and JESD 201 Class 2 whisker tested.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / low-side reference | Connected to ground or lower-potential node; forms clamping path when cathode exceeds VBR |
| Cathode | Reverse-biased input / protected line connection | Connected to supply rail or signal line; conducts only during overvoltage to shunt energy to ground |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature junction capability | TJ = 185 °C enables use in engine bay and power module designs without thermal derating penalties |
| Low clamping ratio (VC/VBR) | ~1.45 - minimizes overvoltage exposure to protected ICs while maintaining robust surge handling |
| Fast response time | < 1 ns - ensures suppression before transient energy couples into sensitive inputs |
| AEC-Q101 qualification | Validated for automotive reliability including temperature cycling, HTRB, and ESD testing |
| Uni-directional architecture | Optimized for DC rail protection where reverse polarity is not expected, reducing capacitance vs. bi-directional types |

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-E3/5BT | Same DO-214AC package; 15 V VBR, but lower PPPM = 400 W and VC = 24.4 V at 16.4 A | Less robust for automotive load dump; suitable for consumer-grade 12 V systems with lower surge severity | Select when cost sensitivity outweighs need for 600 W rating and AEC-Q101 qualification |
| 1.5KE15A | DO-201AD package; same VBR range but higher VC = 23.5 V at 25.5 A and non-AEC-Q101 rated | Larger footprint; lacks automotive qualification and high-temp junction rating (TJ max = 175 °C) | Use only in non-automotive industrial applications where space allows larger case and qualification is not required |
Compared with SMAJ15A-E3/5BT and 1.5KE15A, P6KA15HE3/73 delivers superior surge margin (600 W vs. 400 W/400 W), tighter clamping (22.0 V vs. 24.4 V/23.5 V), and full AEC-Q101 compliance - making it the preferred choice for mission-critical automotive and high-reliability industrial protection.

FAQ
What is the breakdown voltage tolerance for P6KA15HE3/73?
The P6KA15HE3/73 has a specified breakdown voltage range of 13.5 V to 16.3 V at 1.0 mA test current, corresponding to a ±10 % tolerance around the nominal 15 V rating. This tight VBR window ensures consistent turn-on behavior across production lots and supports precise system-level overvoltage threshold design in automotive applications.
Is P6KA15HE3/73 suitable for bidirectional signal line protection?
No, P6KA15HE3/73 is a unidirectional TVS diode and must not be used on AC or bidirectional signal paths. Its design provides clamping only for positive transients relative to ground; reverse polarity events will forward-bias the device and cause failure. For bidirectional protection, a dedicated bi-directional part such as P6SMB15CAHE3/A must be selected instead of P6KA15HE3/73.
Does P6KA15HE3/73 require a heatsink for standard operation?
No, P6KA15HE3/73 operates without a heatsink under normal conditions due to its 5.0 W steady-state power dissipation rating on an infinite heatsink at TL = 75 °C. In typical PCB layouts with 1 oz copper and moderate copper area, thermal rise remains within safe limits even during intermittent surge events - no external heatsink is needed for P6KA15HE3/73 deployment.
What is the maximum leakage current of P6KA15HE3/73 at 12.1 V?
At VWM = 12.1 V and TA = 25 °C, the maximum reverse leakage current for P6KA15HE3/73 is 1.0 μA. At elevated temperature (TJ = 150 °C), leakage increases to 5.0 μA - still well below levels that would affect system quiescent current or sensor bias stability in automotive or industrial applications using P6KA15HE3/73.
How does the clamping voltage of P6KA15HE3/73 compare to similar 15 V TVS diodes?
P6KA15HE3/73 achieves a maximum clamping voltage of 22.0 V at 27.3 A (10/1000 μs), which is 1.5–2.0 V lower than comparable 15 V TVS diodes like SMAJ15A (24.4 V) and 1.5KE15A (23.5 V). This lower VC directly improves system robustness by reducing voltage stress on downstream ICs during surge events - a key differentiator of P6KA15HE3/73 in high-reliability designs.
