Product details
Overview
P6KA16HE3/73 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 14.4 V minimum breakdown voltage (VBR), 12.9 V maximum stand-off voltage (VWM), 600 W peak pulse power (10/1000 µs), 185 °C junction temperature rating, and DO-204AC (DO-15) package - deployed in automotive power supplies and industrial sensor interfaces.
For engineers reviewing the P6KA16HE3/73 datasheet, P6KA16HE3/73 pinout, P6KA16HE3/73 application, or P6KA16HE3/73 equivalent, key selection criteria include clamping voltage (23.5 V at 25.5 A), low leakage (<1 µA at VWM), AEC-Q101 qualification, and high-temperature stability up to +185 °C for under-hood and motor-control environments.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, activated only during reverse-voltage transients exceeding its VWM threshold. Its passivated anisotropic rectifier structure ensures stable breakdown behavior and low incremental surge resistance across temperature extremes.
Designed for repetitive 10/1000 µs surge waveforms at 0.01% duty cycle, it delivers consistent clamping performance with <1 ns response time and maintains reliability under solder dip conditions (275 °C, 10 s) and JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 12.9 V maximum - defines maximum continuous reverse operating voltage before conduction begins |
| VBR (min/max) | 14.4 V / 17.6 V at 1.0 mA - ensures predictable avalanche initiation within tight tolerance band |
| VC @ IPPM | 23.5 V at 25.5 A - clamps induced surges to safe levels for downstream MOSFETs or ICs |
| PPPM | 600 W (10/1000 µs) - handles high-energy transients from inductive switching or load dump |
| TJ max. | +185 °C - enables deployment in high-ambient automotive engine compartments |
| IFSM | 75 A (8.3 ms half-sine) - withstands short-duration surge currents without bond-wire failure |
| Leakage @ VWM | ≤1.0 µA at 25 °C - minimizes standby power loss in always-on circuits |
Pinout & Package

Applications
| Automotive Power Supply Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V power rails in engine control units against load dump and alternator transients. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between battery input and DC-DC converter input stage. Use Value: Limits transient voltage to ≤23.5 V, preventing damage to 36 V-rated input stages while maintaining AEC-Q101 compliance. | Use Scenario: Shielding analog sensor signal lines (e.g., pressure, temperature) from ESD and cable discharge events. IC Role / Device Role / Timing Role: Low-capacitance TVS placed at connector interface to absorb fast-rising transients before reaching ADC front-end. Use Value: Sub-1 µA leakage preserves signal integrity; 23.5 V clamping prevents latch-up in rail-to-rail op-amps powered from 24 V supplies. |
| MOSFET Gate Driver Protection | Telecom Line Card Surge Suppression |
Use Scenario: Safeguarding high-side N-channel MOSFET gate drivers exposed to inductive kickback in motor drives. IC Role / Device Role / Timing Role: Clamp placed between gate driver output and MOSFET gate to limit VGS overshoot.

IC Role / Device Role / Timing Role: Standoff device in series with primary MOV-based protection to refine clamping level and extend system lifetime. Use Value: 600 W PPPM rating handles repeated lightning-induced surges; DO-15 form factor allows manual rework and high-density placement. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A-E3/5AT | Lower PPPM (400 W), same VWM/VBR, SMA package (surface-mount) | Not AEC-Q101 qualified; limited to commercial-temperature industrial use | Select when board space is constrained and automotive qualification is not required |
| 1.5KE16A | Higher VC (25.6 V), same DO-15 package, 1500 W PPPM but larger footprint | Higher surge capacity but less precise clamping; no AEC-Q101 validation | Choose for cost-sensitive non-automotive designs needing higher single-pulse energy handling |
Compared with SMAJ16A-E3/5AT and 1.5KE16A, P6KA16HE3/73 offers superior thermal robustness (185 °C vs. 150 °C), automotive qualification, and tighter clamping - making it optimal for space-constrained, high-reliability 12 V systems where long-term field stability is critical.

FAQ
What is the maximum clamping voltage of the P6KA16HE3/73 under rated surge current?
The P6KA16HE3/73 has a maximum clamping voltage (VC) of 23.5 V at its rated peak pulse current (IPPM) of 25.5 A, measured using the standard 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and ensures reliable protection of 24 V-rated components connected downstream. The P6KA16HE3/73 achieves this with low incremental surge resistance and stable avalanche characteristics.
Is the P6KA16HE3/73 qualified for automotive applications?
Yes, the P6KA16HE3/73 is explicitly AEC-Q101 qualified, as confirmed in the Vishay datasheet (Document Number 88368, Revision 20-Dec-13). It undergoes rigorous stress testing including high-temperature reverse bias, temperature cycling, and mechanical shock - validating its suitability for under-hood and powertrain applications. The P6KA16HE3/73 also supports solder dip at 275 °C for 10 seconds per JESD22-B106.
What is the polarity configuration of the P6KA16HE3/73?
The P6KA16HE3/73 is a unidirectional TVS diode, meaning it functions as a reverse-biased avalanche clamp and conducts only when the cathode is at a higher potential than the anode. Polarity is marked by a color band on the cathode end of the DO-204AC package. The P6KA16HE3/73 does not provide bidirectional protection and must be oriented correctly in-circuit to protect against negative-going transients on positive rails.
How does the P6KA16HE3/73 compare to the P6KA16A variant?
The P6KA16HE3/73 has a VBR range of 14.4 V to 17.6 V at 1.0 mA, while the P6KA16A variant specifies 15.2 V to 16.8 V - indicating tighter breakdown tolerance. Both share identical VWM (13.6 V), VC (22.5 V), and thermal ratings. The P6KA16HE3/73 uses the HE3 suffix denoting RoHS-compliance and JESD201 Class 2 whisker resistance, whereas P6KA16A may use alternate suffixes with different plating or packaging.
What is the junction temperature limit for continuous operation of the P6KA16HE3/73?
The P6KA16HE3/73 supports continuous operation from -65 °C to +185 °C junction temperature, with derating applied above 25 °C ambient per the power derating curve in Figure 5 of the datasheet. At TL = 75 °C (lead temperature), its steady-state power dissipation is rated at 5.0 W on an infinite heatsink. This 185 °C TJ max. rating makes the P6KA16HE3/73 suitable for high-ambient applications such as engine control modules and industrial motor drives.
