Product details
Overview
P6KE16CHE3/73 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 16 V breakdown voltage (VBR min = 15.2 V, max = 16.8 V), 13.6 V stand-off voltage (VWM), 22.5 V maximum clamping voltage at 26.7 A peak pulse current, 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 P6KE16CHE3/73 datasheet, P6KE16CHE3/73 pinout, P6KE16CHE3/73 application, or P6KE16CHE3/73 equivalent, key selection criteria include verified AEC-Q101 qualification, DO-204AC (DO-15) package compatibility, uni-directional polarity with cathode band marking, and thermal resistance (RθJL = 20 °C/W) critical for sustained surge duty in engine control modules.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ at VWM), but triggers into low-impedance conduction when transient voltage exceeds VBR, clamping the line to ≤22.5 V at 26.7 A. Its glass-passivated junction ensures stable leakage (<1 µA at 13.6 V) and fast response (<1 ns).
Designed for single-pulse and low-duty-cycle repetitive transients (0.01 %), it sustains 100 A non-repetitive forward surge (8.3 ms half-sine) and operates across –55 °C to +175 °C junction temperature. The HE3 suffix confirms AEC-Q101 qualification and JESD 201 Class 2 whisker resistance - essential for automotive under-hood deployment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 15.2 V / 16.8 V - defines precise breakdown threshold for reliable triggering above system operating voltage |
| VWM | 13.6 V - maximum continuous reverse working voltage before leakage exceeds 1 µA |
| VC @ IPPM | 22.5 V at 26.7 A - clamping voltage limiting downstream IC stress during 10/1000 µs surge |
| PPPM | 600 W - peak transient power absorption capacity without failure under standardized waveform |
| IFSM | 100 A - surge current handling for 8.3 ms half-sine, enabling robustness against load dump events |
| TJ max | +175 °C - extended junction temperature rating supporting under-hood automotive placement |
| RθJL | 20 °C/W - low junction-to-lead thermal resistance enabling effective heat transfer to PCB copper |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102. Cathode identified by color band on body end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / transient return path | Connected to protected line ground or low-side reference; enables clamping to GND during positive transients |
| Cathode | Reverse-biased terminal / clamping node | Marked with band; connected to protected line (e.g., 12 V rail); conducts when VAK > VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control, body electronics, and ADAS sensor interfaces |
| Glass passivated junction | Ensures stable VBR tolerance (±5 %), low leakage (<1 µA), and long-term reliability under thermal cycling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A-E3/57T | Lower PPPM (400 W), SMA package (surface-mount), VC = 26.0 V @ 15.4 A | Better suited for space-constrained PCB layouts; lower surge margin for automotive load dump | Select when board area is limited and peak surge energy does not exceed 400 W |
| 1.5KE16A | Same DO-15 package, higher IPPM (38.5 A), VC = 25.0 V, but commercial-grade (non-AEC-Q101) | Lacks automotive qualification; suitable for industrial/commercial power supplies only | Choose for cost-sensitive non-automotive designs requiring identical footprint and higher current handling |
Compared with SMAJ16A-E3/57T and 1.5KE16A, P6KE16CHE3/73 delivers AEC-Q101 assurance and optimized clamping (22.5 V) for safety-critical automotive nodes, while maintaining legacy through-hole assembly compatibility and superior thermal dissipation via RθJL = 20 °C/W.

FAQ
What is the exact breakdown voltage range for P6KE16CHE3/73?
The P6KE16CHE3/73 has a guaranteed breakdown voltage (VBR) range of 15.2 V to 16.8 V at 1.0 mA test current, measured per ANSI/IEEE C62.35. This tight ±5 % tolerance ensures consistent triggering behavior across production lots and temperature extremes from –55 °C to +175 °C, making P6KE16CHE3/73 suitable for precision overvoltage protection in automotive ECUs where supply rail margins are narrow.
Is P6KE16CHE3/73 compatible with lead-free reflow soldering processes?
No - P6KE16CHE3/73 uses axial DO-204AC (DO-15) packaging with matte tin-plated leads rated for solder dip only (275 °C max, 10 s per JESD 22-B106). It is not qualified for lead-free reflow (260 °C peak, 10–15 s). For reflow-compatible alternatives, consider surface-mount equivalents like SMAJ16A-E3/57T, but note P6KE16CHE3/73 remains optimal for wave-soldered automotive harness interfaces and legacy through-hole designs.
Does P6KE16CHE3/73 meet AEC-Q101 requirements for automotive use?
Yes - the HE3 suffix explicitly denotes AEC-Q101 qualification per the Vishay datasheet (Doc. #88369, Rev. 18-Sep-12). P6KE16CHE3/73 passes stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing (uHAST), validating its suitability for under-hood engine control, body control modules, and ADAS sensor units where reliability under thermal and mechanical stress is critical.
How does the clamping performance of P6KE16CHE3/73 compare to similar 16 V TVS diodes?
P6KE16CHE3/73 clamps to 22.5 V at 26.7 A (10/1000 µs), achieving a clamping ratio (VC/VBR) of ~1.42 - among the lowest in the P6KE family. This outperforms generic 16 V TVS diodes like 1.5KE16A (VC = 25.0 V) and provides tighter protection margin for 3.3 V or 5 V logic interfaces downstream. The low incremental surge resistance inherent to its glass-passivated chip junction directly enables this superior clamping behavior in P6KE16CHE3/73.
Can P6KE16CHE3/73 be used in bi-directional protection configurations?
No - P6KE16CHE3/73 is strictly uni-directional, indicated by the "A" suffix and cathode band marking. Bi-directional variants require the "CA" suffix (e.g., P6KE16CA). Using P6KE16CHE3/73 in AC or floating-line applications would result in forward conduction during negative half-cycles, causing failure. For bi-directional protection at ~16 V standoff, specify P6KE16CHE3/73's counterpart P6KE16CHE3/73 is not applicable; instead use P6KE16CAHE3/73, which has symmetric VBR and no polarity marking.
