Product details
Overview
P6KE16HE3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for primary overvoltage protection of DC power rails and signal lines. It features 16 V breakdown voltage (VBR min/max = 15.2–16.8 V), 13.6 V standoff voltage (VWM), 22.5 V clamping voltage at 26.7 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive ECU input protection and industrial sensor interface circuits.
For engineers reviewing the P6KE16HE3/73 datasheet, P6KE16HE3/73 pinout, P6KE16HE3/73 application, or P6KE16HE3/73 equivalent, this AEC-Q101 qualified TVS offers validated surge immunity for 12 V automotive systems, low-leakage reverse operation (<1.0 µA at VWM), and thermal robustness up to 175 °C junction temperature - critical for under-hood electronics and motor control feedback paths.
Technical Context
The P6KE16HE3/73 operates as a silicon avalanche diode with glass-passivated junction, enabling sub-nanosecond response to transient events. Its unidirectional polarity uses a cathode band marking and delivers precise clamping within ±5 % of rated VC across production lots, with temperature coefficient of 0.086 %/°C ensuring stable VBR over -55 °C to +175 °C.
It sustains 100 A non-repetitive forward surge current (IFSM) per 8.3 ms half-sine wave and exhibits 20 °C/W junction-to-lead thermal resistance - allowing direct PCB trace heat sinking without external heatsinks in moderate-duty applications such as CAN bus line protection and microcontroller I/O rail clamping.
Key Specifications

IC Role / Device Role / Timing Role: Secondary protection stage after polymer PTC, clamping residual energy after upstream current limiting. Use Value: 22.5 V clamping prevents overvoltage damage to USB transceiver ICs rated for absolute max 6.5 V on VBUS pins. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A | Same VWM (13.6 V) and VC (22.5 V), but 400 W PPPM rating and SMA package (smaller footprint, higher RθJA) | Limited to lower-energy transients; unsuitable for automotive load-dump where 600 W capability is mandated | Select P6KE16HE3/73 when 600 W surge handling and AEC-Q101 compliance are required; choose SMAJ16A only for space-constrained consumer-grade designs |
| 1.5KE16A | Identical electrical specs (VBR, VWM, VC, PPPM), but TO-204AE (DO-41) package and commercial-grade (non-AEC-Q101) qualification | No automotive qualification; not accepted in OEM automotive BOMs requiring PPAP documentation and stress test validation | Use P6KE16HE3/73 for automotive or industrial applications needing AEC-Q101; use 1.5KE16A only for cost-sensitive, non-automotive prototypes |
Compared with SMAJ16A and 1.5KE16A, the P6KE16HE3/73 uniquely combines 600 W surge rating, AEC-Q101 qualification, and DO-15 mechanical robustness - making it the only option qualified for under-hood automotive deployment where thermal cycling and vibration endurance are mandatory.

FAQ
What is the clamping voltage of the P6KE16HE3/73 under maximum surge conditions?
The P6KE16HE3/73 clamps to a maximum of 22.5 V at its rated peak pulse current of 26.7 A (10/1000 µs waveform). This value is measured per JEDEC standards and guarantees that downstream circuitry sees no more than 22.5 V during standardized surge events - a critical parameter for protecting 3.3 V or 5 V logic rails. The P6KE16HE3/73 maintains this clamping performance across its full operating temperature range of −55 °C to +175 °C.
Is the P6KE16HE3/73 suitable for automotive applications?
Yes, the P6KE16HE3/73 is AEC-Q101 qualified and specifically designed for automotive use, including engine control units, body electronics, and ADAS modules. Its HE3 suffix confirms compliance with JESD 201 Class 2 whisker resistance and RoHS requirements, and its 175 °C maximum junction temperature supports under-hood placement. The P6KE16HE3/73 meets ISO 7637-2 Pulse 1 and Pulse 3a/b immunity requirements when properly mounted with adequate copper area for thermal dissipation.
How does the P6KE16HE3/73 differ from the standard P6KE16A variant?
The P6KE16HE3/73 differs from P6KE16A in three key ways: it carries the HE3 suffix indicating AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, it is packaged in 7" tape-and-reel (vs. standard 13" for P6KE16A-E3/54), and it is screened for automotive-grade reliability including extended temperature cycling and HTOL testing. The P6KE16HE3/73 shares identical electrical characteristics (VBR, VWM, VC) with P6KE16A but is approved for production automotive BOMs where P6KE16A is not.
What is the reverse leakage current specification for the P6KE16HE3/73 at rated standoff voltage?
The P6KE16HE3/73 exhibits a maximum reverse leakage current (ID) of 1.0 µA at its standoff voltage (VWM) of 13.6 V and ambient temperature of 25 °C. This low leakage ensures minimal power loss and signal integrity impact in high-impedance sensing circuits. At elevated temperatures (e.g., 125 °C), leakage remains below 50 µA - verified per AEC-Q101 thermal stress testing - confirming stable performance in under-hood environments.
Can the P6KE16HE3/73 be used in bidirectional protection configurations?
No, the P6KE16HE3/73 is a unidirectional TVS diode and is not rated for bidirectional operation. Its cathode band marking and electrical specifications (e.g., forward voltage drop of 3.5 V at 50 A) apply only in the forward direction. For bidirectional protection, Vishay specifies part numbers with "CA" suffix (e.g., P6KE16CA); using P6KE16HE3/73 in AC or floating-line applications risks asymmetric clamping and potential failure. Always verify polarity alignment before placing the P6KE16HE3/73 in circuit.
