Product details
Overview
P6KA16AHE3/73 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection of sensitive semiconductor devices such as MOSFETs and ICs in power rails and signal lines. It features a 13.6 V stand-off voltage (VWM), 15.2–16.8 V breakdown range (VBR), 600 W peak pulse power (10/1000 μs), 26.7 A peak pulse current (IPPM), and clamps to ≤22.5 V at rated surge - validated for automotive-grade reliability with AEC-Q101 qualification and 185 °C junction rating.
For engineers reviewing the P6KA16AHE3/73 datasheet, P6KA16AHE3/73 pinout, P6KA16AHE3/73 application, or P6KA16AHE3/73 equivalent, this device is selected for high-temperature industrial motor drives, automotive body control modules, and telecom power supply rail protection where fast clamping (<1 ns response), low incremental surge resistance, and stable operation up to TJ = 185 °C are critical design requirements.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for junction stability under repetitive surge stress. Its unidirectional polarity and DO-204AC (DO-15) package support integration into DC-biased circuits requiring precise clamping without reverse conduction during normal operation.
The device delivers 600 W peak pulse power per 10/1000 μs waveform with 0.01 % duty cycle, and maintains clamping performance across -65 °C to +185 °C operating temperature range. Its 0.080 %/°C VBR temperature coefficient ensures predictable voltage threshold drift in thermally demanding environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 13.6 V - maximum continuous reverse voltage before significant leakage; sets safe operating margin below circuit nominal DC rail. |
| VBR (Breakdown Voltage) | 15.2–16.8 V at 1 mA - guaranteed avalanche initiation range; defines minimum overvoltage threshold for reliable clamping activation. |
| VC (Clamping Voltage) | ≤22.5 V at IPPM = 26.7 A - peak voltage seen by protected circuit during full-rated surge; determines residual stress on downstream components. |
| PPPM (Peak Pulse Power) | 600 W (10/1000 μs) - energy-handling capacity for standardized lightning/surge transients; enables compliance with IEC 61000-4-5 Level 3. |
| TJ max. | +185 °C - maximum junction temperature rating; supports under-hood automotive and high-ambient industrial deployments without derating. |
| AEC-Q101 Qualified | Yes - certified for automotive electronic systems per stress test requirements including HTRB, HTGB, and temperature cycling. |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with matte tin-plated leads, UL 94 V-0 molding, and JESD 201 Class 2 whisker resistance. |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, molded epoxy case with cathode indicated by color band. Leads are matte tin-plated, solderable per J-STD-002 and JESD 22-B102, rated for 275 °C solder dip (10 s max).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in unidirectional TVS configuration; conducts during forward surge events. |
| Cathode | Reverse-biased clamping terminal | Connected to protected line (e.g., 12 V rail); avalanche breakdown occurs here when reverse voltage exceeds VBR, shunting surge current to anode. |
Key Features
| Feature | Design Value |
|---|---|
| Junction passivation | Optimized anisotropic rectifier process ensures stable VBR and low leakage (<1 μA at VWM) over lifetime and temperature. |
| High-temperature capability | TJ max. = +185 °C enables use in engine control units and industrial inverters without thermal derating penalties. |
| Fast response time | <1 ns turn-on latency minimizes voltage overshoot during ESD or switching transients, protecting fast-switching MOSFET gates. |
| Low incremental surge resistance | Ensures minimal voltage rise above VC during high di/dt events, preserving clamping effectiveness under real-world surge waveforms. |
| AEC-Q101 qualification | Validated for automotive applications including BCM, lighting control, and infotainment power rails with zero early-life failure risk. |
Applications
| Automotive Body Control Module (BCM) | Industrial Motor Drive DC Bus |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A | Same VWM (13.6 V), identical DO-214AC package; slightly higher VC (23.0 V vs. 22.5 V) and lower TJ max. (150 °C vs. 185 °C). | Not AEC-Q101 qualified; suitable for commercial/industrial but not automotive deployment. | Select SMAJ16A only if AEC-Q101 is not required and PCB layout allows SMA footprint change. |
| 1.5KE16A | Higher PPPM (1500 W), larger DO-201AD package; same VWM/VBR range but 20 % higher clamping voltage (27.0 V) and no AEC-Q101 certification. | Designed for higher-energy surges; less suitable for space-constrained automotive modules due to larger footprint and thermal mass. | Choose 1.5KE16A only when surge energy exceeds 600 W and board area permits larger axial package. |
Compared with SMAJ16A and 1.5KE16A, P6KA16AHE3/73 uniquely combines AEC-Q101 qualification, DO-15 form factor, and 185 °C operation - making it the only drop-in solution for thermally aggressive automotive power nodes requiring long-term reliability without layout or thermal redesign.

FAQ
What is the clamping voltage of the P6KA16AHE3/73 at its rated peak pulse current?
The P6KA16AHE3/73 has a maximum clamping voltage (VC) of 22.5 V when subjected to its rated peak pulse current (IPPM) of 26.7 A under the standard 10/1000 μs waveform. This value is measured per JEDEC test conditions and guarantees the upper voltage limit imposed on protected circuitry during full-rated surge events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is the P6KA16AHE3/73 suitable for automotive applications?
Yes, the P6KA16AHE3/73 is AEC-Q101 qualified and rated for operation up to +185 °C junction temperature, making it fully compliant for automotive use in body control modules, lighting systems, and power distribution units. Its DO-204AC package, matte tin-plated leads, and JESD 201 Class 2 whisker resistance further validate its suitability for automotive production environments.
What does the "HE3/73" suffix indicate in P6KA16AHE3/73?
The "HE3" suffix denotes RoHS-compliant construction with matte tin-plated leads and JESD 201 Class 2 whisker resistance; "/73" specifies the packaging variant - 73 indicates 13-inch diameter paper tape and reel, with 4000 units per reel. This format ensures compatibility with automated SMT placement equipment and meets Vishay's standard logistics coding for traceable, high-reliability distribution.
How does the P6KA16AHE3/73 differ from the non-A version (P6KA16HE3/73)?
The P6KA16AHE3/73 features tighter VBR tolerance (15.2–16.8 V) versus P6KA16HE3/73 (14.4–17.6 V), lower maximum leakage current (1.0 μA vs. 2.0 μA at VWM), and improved temperature coefficient (0.080 %/°C vs. 0.086 %/°C). These enhancements provide more predictable clamping behavior in precision power rail protection applications.
Can the P6KA16AHE3/73 be used in bidirectional configurations?
No - the P6KA16AHE3/73 is unidirectional only, as confirmed in the Vishay datasheet. It conducts in forward bias and clamps in reverse bias above VBR. For bidirectional protection, a separate device such as the P6SMB16CA or dual-diode array would be required; using two P6KA16AHE3/73 devices in series opposition is not recommended due to mismatched VBR and thermal coupling risks.
