Product details
Overview
P6KE22-E3/73 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 600 W peak pulse power (10/1000 μs), 20.9–23.1 V breakdown voltage at 1 mA, 18.8 V standoff voltage, 30.6 V clamping voltage at 19.6 A peak pulse current, and operates from –55 °C to +175 °C - deployed in automotive sensor interfaces and industrial I/O modules.
For engineers reviewing the P6KE22-E3/73 datasheet, P6KE22-E3/73 pinout, P6KE22-E3/73 application, or P6KE22-E3/73 equivalent, this page delivers verified electrical parameters, thermal derating behavior, clamping performance under surge conditions, RoHS-compliant packaging details, and AEC-Q101 qualification status - all specific to the P6KE22-E3/73 variant.
Technical Context
This unidirectional TVS diode uses a glass-passivated silicon junction to achieve fast response time (<1 ns) and low incremental surge resistance. Its clamping action begins at 18.8 V (VWM), with guaranteed breakdown between 20.9 V and 23.1 V at 1 mA test current, and limits transient voltages to ≤30.6 V at 19.6 A (10/1000 μs waveform).
Thermal design relies on RθJL = 20 °C/W (junction-to-lead) and RθJA = 75 °C/W (junction-to-ambient), enabling 5.0 W steady-state dissipation at TL = 75 °C. The device meets AEC-Q101 stress testing requirements and supports soldering per J-STD-002 and JESD 22-B102.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 μs) | 600 W - sustains high-energy transients without failure, suitable for load-dump or inductive switching events |
| Standoff Voltage (VWM) | 18.8 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 μA |
| Breakdown Voltage (VBR) | 20.9–23.1 V at 1 mA - defines onset of avalanche conduction; tight tolerance ensures predictable turn-on |
| Clamping Voltage (VC) | 30.6 V at 19.6 A - upper voltage limit imposed during surge, protecting downstream ICs rated ≤30 V |
| Operating Temperature | –55 °C to +175 °C - supports under-hood automotive and industrial environments without derating |
| Package | DO-204AC (DO-15) - axial-leaded, UL 94 V-0 molded epoxy housing with matte tin-plated leads |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |
Pinout & Package

|---|---|
|
Use Scenario: Protecting CAN/LIN transceiver inputs and analog sensor feeds (e.g., pressure, temperature) from ISO 16750-2 jump-start and load-dump surges. IC Role / Device Role / Timing Role: Unidirectional shunt clamp placed between signal line and ground, absorbing energy before it reaches the transceiver's ESD structure. Use Value: Limits transient voltage to ≤30.6 V, preserving integrity of 3.3 V or 5 V logic interfaces and avoiding latch-up in automotive-grade MCUs. |
Use Scenario: Safeguarding 24 V digital input channels on programmable logic controllers against inductive kickback from solenoid or relay coils. IC Role / Device Role / Timing Role: Primary overvoltage clamp across input terminals, triggered within <1 ns to suppress spikes up to 100 V. Use Value: Prevents false triggering and component damage by clamping transients before they exceed the 30 V absolute maximum rating of input buffer ICs. |
| DC Power Rail Protection | Consumer Appliance Motor Control |
|
Use Scenario: Guarding 12–24 V DC power distribution networks in telecom power supplies and PoE injectors against lightning-induced surges. IC Role / Device Role / Timing Role: Standoff-rated TVS placed upstream of DC-DC converters and LDOs to absorb line-side transients. Use Value: Maintains system uptime by limiting rail excursions to 30.6 V, preventing brownout resets and regulator shutdown during 600 W surge events. |
Use Scenario: Shielding microcontroller GPIOs and gate drivers in washing machine motor control boards from commutation noise and EMI. IC Role / Device Role / Timing Role: Localized clamping element on motor driver enable lines and feedback paths, reducing conducted emissions. Use Value: Enables compliance with IEC 61000-4-4 (EFT) and IEC 61000-4-5 (surge) without additional filtering components. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ22A | DO-214AA package; 22 V VBR min/max tighter (20.9–23.1 V same), but lower 600 W rating applies at 10/1000 μs with 0.01% duty cycle | Surface-mount alternative for space-constrained PCBs; requires rework of footprint and thermal relief design | Select SMBJ22A when board area is limited and SMT assembly is preferred; verify RθJA margin given smaller thermal mass |
| 1.5KE22A | Same DO-204AC package but higher 1500 W peak pulse rating; VBR 20.9–23.1 V, VC 33.2 V at 45.3 A - higher clamping voltage | Used where higher surge immunity is required (e.g., outdoor industrial enclosures), but adds 2.6 V overhead vs. P6KE22-E3/73 | Choose 1.5KE22A only if system-level testing confirms need for >600 W capability; otherwise P6KE22-E3/73 offers better clamping efficiency |
Compared with SMBJ22A and 1.5KE22A, P6KE22-E3/73 delivers optimal balance of axial-leaded manufacturability, 30.6 V clamping headroom, and AEC-Q101-ready qualification - making it preferred for cost-sensitive, high-volume automotive and industrial designs where leaded assembly remains standard.

FAQ
What is the clamping voltage of P6KE22-E3/73 at its rated peak pulse current?
The P6KE22-E3/73 has a maximum clamping voltage (VC) of 30.6 V at 19.6 A peak pulse current (10/1000 μs waveform). This value is measured under standardized surge conditions and represents the upper voltage limit imposed on the protected circuit during transient events - critical for ensuring downstream components remain within their absolute maximum ratings. The P6KE22-E3/73 maintains this clamping performance across its full operating temperature range.
Is P6KE22-E3/73 suitable for automotive applications?
Yes, P6KE22-E3/73 is RoHS-compliant and manufactured to meet AEC-Q101 stress test requirements when ordered with the HE3 suffix (e.g., P6KE22AHE3/73). While the E3 suffix denotes commercial-grade RoHS compliance, the underlying die and construction are identical - allowing direct qualification path. Engineers deploying P6KE22-E3/73 in automotive systems should confirm qualification status with Vishay documentation and use HE3 variants for production releases requiring formal AEC-Q101 certification.
How does the standoff voltage (VWM) of P6KE22-E3/73 relate to system operating voltage?
The standoff voltage (VWM) of P6KE22-E3/73 is 18.8 V - the maximum DC or continuous reverse voltage the device can withstand without exceeding 1.0 μA leakage. For reliable operation, system nominal voltage must be ≤80–90% of VWM; thus, P6KE22-E3/73 is optimized for 15–18 V DC rails (e.g., automotive 12 V systems with ripple). Exceeding VWM risks accelerated aging or premature conduction, so proper margining is essential in P6KE22-E3/73-based designs.
What is the thermal resistance profile of P6KE22-E3/73, and how does it affect layout?
P6KE22-E3/73 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient (RθJA) of 75 °C/W. Because heat is primarily conducted through the leads, PCB layout must provide adequate copper area (≥100 mm² per lead) and short, wide traces to minimize thermal impedance. Without sufficient copper, the 5.0 W steady-state power dissipation rating cannot be achieved - making thermal design as critical as electrical placement for P6KE22-E3/73 reliability.
Can P6KE22-E3/73 be used in bidirectional configurations?
No, P6KE22-E3/73 is a unidirectional TVS diode, identified by the "A" suffix and cathode band marking. Bidirectional operation requires the "CA" suffix (e.g., P6KE22CA), which contains two opposing avalanche junctions. Using P6KE22-E3/73 in AC or floating signal paths will result in forward conduction during negative half-cycles, causing failure. Always match polarity: P6KE22-E3/73 for DC rails with defined ground reference; P6KE22CA for symmetrical transients like data lines or AC-coupled sensors.
