Product details
Overview
P6KE22HE3/73 from Vishay General Semiconductor is a uni-directional 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 600 W peak pulse power (10/1000 μs), 20.9–23.1 V breakdown voltage at 1 mA, 18.8 V stand-off voltage, 30.6 V clamping voltage at 19.6 A peak pulse current, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the P6KE22HE3/73 datasheet, P6KE22HE3/73 pinout, P6KE22HE3/73 application, or P6KE22HE3/73 equivalent, key selection criteria include clamping performance under 10/1000 μs surge, thermal resistance (RθJL = 20 °C/W), RoHS-compliant matte tin plating, and compatibility with J-STD-002 solderability standards in harsh environments.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR, it avalanches to divert transient energy away from downstream ICs or MOSFETs. Its glass-passivated junction ensures stable breakdown and low leakage (<1.0 μA at 18.8 V).
Designed for single-pulse and low-duty-cycle repetitive transients, it sustains 100 A non-repetitive forward surge (8.3 ms half-sine) and maintains operation from –55 °C to +175 °C junction temperature, with derating above 25 °C ambient per Fig. 2 and Fig. 5.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 20.9 V / 23.1 V at 1 mA - defines precise avalanche initiation threshold for reliable overvoltage detection |
| VWM | 18.8 V - maximum continuous reverse operating voltage before leakage rises significantly |
| VC @ IPPM | 30.6 V at 19.6 A - clamping voltage during 600 W 10/1000 μs surge, limiting stress on protected circuitry |
| PPPM | 600 W - peak transient power handling capability, enabling robust protection against lightning-induced or inductive-switching surges |
| RθJL | 20 °C/W - low junction-to-lead thermal resistance supports high-power pulse dissipation without external heatsinking |
| TJ max | +175 °C - extended junction temperature rating allows use in under-hood automotive and industrial power supply applications |
| AEC-Q101 | Qualified - validated for automotive electronics per stress test requirements including HTOL, TC, and HTRB |
Pinout & Package
Package: DO-204AC (DO-15), molded epoxy case with matte tin-plated leads; cathode indicated by color band on body end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction path (for uni-directional operation) | Connected to system ground or low-side return; enables clamping only during reverse overvoltage events |
| Cathode | Protected line connection point | Connected to line being protected (e.g., 24 V rail); avalanche occurs between cathode and anode when VAK > VBR |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling and humidity exposure |
| 600 W peak pulse power (10/1000 μs) | Provides industry-standard surge immunity for IEC 61000-4-5 Level 3 (1 kV/2 Ω) and ISO 7637-2 Pulse 1/2/5a |
| AEC-Q101 qualification | Validates suitability for automotive powertrain, body control, and ADAS modules requiring zero-failure field performance |
| RoHS-compliant HE3 suffix | Indicates AEC-Q101 qualification and JESD 201 Class 2 whisker resistance - critical for lead-free reflow and long-life deployments |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., <1 ns rise time), improving protection margin for sensitive gate drivers |
Applications
| Automotive Power Supply Protection | Industrial Sensor Interface Protection |
|---|---|
|
Use Scenario: Protecting 24 V battery-fed ECUs from load dump (ISO 7637-2 Pulse 5a) and alternator switching transients. IC Role / Device Role / Timing Role: Shunt TVS placed between VBAT and GND, clamping surges within 1 ns to limit voltage seen by LDOs and microcontrollers. Use Value: With 30.6 V clamping at 19.6 A, P6KE22HE3/73 holds rail voltage below 32 V - well under 36 V absolute max ratings of common automotive PMICs. |
Use Scenario: Safeguarding analog sensor outputs (e.g., pressure, temperature) connected to MCU ADC inputs in factory automation systems. IC Role / Device Role / Timing Role: Low-capacitance uni-directional TVS installed on each signal line, referenced to local ground to suppress ESD and cable discharge events. Use Value: 1.0 μA leakage at 18.8 V prevents signal offset errors; DO-15 footprint allows placement directly at connector entry point without board area penalty. |
| DC Motor Drive Gate Protection | Telecom Line Card Surge Suppression |
|
Use Scenario: Shielding N-channel MOSFET gates from inductive kickback during PWM commutation in BLDC motor controllers. IC Role / Device Role / Timing Role: TVS mounted between gate and source, clamping negative-going spikes that could exceed ±20 V gate oxide limits. Use Value: 20.9–23.1 V VBR ensures conduction before gate damage occurs; fast response (<1 ns) prevents cumulative oxide degradation across millions of cycles. |
Use Scenario: Front-end protection of Ethernet PHY or RS-485 transceivers exposed to lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: Primary shunt device in multi-stage protection scheme, absorbing bulk energy before secondary TVS or GDT stages. Use Value: 600 W rating handles 10/1000 μs surges up to 1.2 kV; UL 94 V-0 molding compound meets telecom safety standards for enclosed line cards. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ22A-E3/57T | Lower peak pulse power (400 W), SMA package (smaller footprint, higher RθJA) | Better suited for space-constrained consumer PCBs; less robust for automotive load dump | Select when board area is critical and surge severity is limited to IEC 61000-4-2/4-4 |
| 1.5KE22A | Same DO-15 package, 1500 W rating, higher VC (35.5 V), no AEC-Q101 qualification | Higher power handling but wider VBR tolerance (±10 % vs. ±5 %) and no automotive qualification | Choose for industrial mains-powered equipment where cost and raw power dominate over automotive compliance |
Compared with SMAJ22A-E3/57T and 1.5KE22A, P6KE22HE3/73 delivers optimal balance of AEC-Q101 validation, 600 W surge capacity, tight 20.9–23.1 V VBR window, and proven DO-15 manufacturability - making it the preferred choice for Tier 1 automotive and high-reliability industrial designs.

FAQ
What is the clamping voltage of P6KE22HE3/73 at its rated peak pulse current?
The clamping voltage (VC) of P6KE22HE3/73 is 30.6 V at 19.6 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88369 and represents the maximum voltage imposed on the protected circuit during a full-rated surge event. The P6KE22HE3/73 maintains this clamping performance across its qualified temperature range.
Is P6KE22HE3/73 suitable for automotive applications?
Yes, P6KE22HE3/73 is AEC-Q101 qualified and explicitly rated for automotive use per Vishay's documentation. Its HE3 suffix denotes AEC-Q101 qualification, JESD 201 Class 2 whisker resistance, and RoHS compliance - meeting requirements for engine control units, body electronics, and ADAS subsystems. The P6KE22HE3/73 operates reliably from –55 °C to +175 °C junction temperature.
How does the P6KE22HE3/73 differ from the commercial-grade P6KE22A-E3/73?
The P6KE22HE3/73 differs from P6KE22A-E3/73 solely in qualification level: the "H" prefix indicates AEC-Q101 qualification, while the base P6KE22A-E3/73 is commercial grade. Both share identical electrical specs (VBR, VC, PPPM), DO-204AC package, and RoHS compliance. The P6KE22HE3/73 undergoes additional stress testing per AEC-Q101, ensuring suitability for automotive deployment.
What is the maximum reverse leakage current for P6KE22HE3/73 at its stand-off voltage?
The maximum reverse leakage current (ID) for P6KE22HE3/73 is 1.0 μA at its stand-off voltage (VWM) of 18.8 V, measured at TA = 25 °C. This low leakage ensures minimal impact on power rail efficiency and signal integrity in always-on systems. The P6KE22HE3/73 maintains leakage below 5.0 μA up to 85 °C ambient per thermal derating curves.
Can P6KE22HE3/73 be used in bi-directional protection configurations?
No, P6KE22HE3/73 is a uni-directional TVS diode and is not rated for bi-directional operation. Its datasheet specifies polarity (cathode band marked) and lists breakdown only in reverse bias. For bi-directional protection, Vishay offers CA-suffixed variants such as P6KE22CA; using P6KE22HE3/73 in AC or floating-line applications risks failure due to forward conduction during negative half-cycles.
