Product details
Overview
P6KE22AHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. 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 maximum clamping voltage at 19.6 A, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the P6KE22AHE3/54 datasheet, P6KE22AHE3/54 pinout, P6KE22AHE3/54 application, or P6KE22AHE3/54 equivalent, this page delivers verified electrical parameters, thermal derating behavior, clamping performance under surge conditions, RoHS-compliant AEC-Q101 qualification status, and direct substitution guidance for circuit protection design in automotive ECUs, industrial I/O modules, and sensor interface lines.
Technical Context
The P6KE22AHE3/54 operates as a silicon avalanche diode with glass-passivated junction, enabling fast response time (<1 ns) and low incremental surge resistance. Its unidirectional polarity uses a cathode band marking and exhibits 3.5 V forward voltage at 50 A, supporting robust surge handling without latch-up.
Thermal performance is defined by 20 °C/W junction-to-lead resistance and 75 °C/W junction-to-ambient resistance, with power derating linear from 5.0 W at 75 °C lead temperature down to zero at 175 °C junction temperature. It complies with JESD 22-B106 (275 °C solder dip, 10 s) and JESD 201 Class 2 whisker testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 20.9 V / 23.1 V at 1 mA - defines minimum voltage at which avalanche conduction begins reliably |
| VWM | 18.8 V - maximum continuous reverse operating voltage before leakage exceeds 1 μA |
| VC @ IPPM | 30.6 V at 19.6 A - clamped voltage during 600 W transient, limiting stress on downstream ICs |
| PPPM | 600 W (10/1000 μs waveform) - peak surge energy absorption capability per single event |
| IFSM | 100 A (8.3 ms half-sine) - non-repetitive forward surge current rating for fuse coordination |
| TJ max | +175 °C - maximum junction temperature enabling operation in under-hood automotive environments |
| RθJL | 20 °C/W - thermal resistance from junction to lead, critical for PCB copper pour sizing in high-power surge events |
Pinout & Package

Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control, body electronics, and ADAS sensor interfaces |
| Glass passivated junction | Enables stable breakdown voltage over lifetime and improved humidity resistance vs. epoxy-passivated alternatives |
| 600 W peak pulse power | Supports IEC 61000-4-5 Level 4 (4 kV) surge immunity without external series impedance |
| Low clamping ratio (VC/VBR ≈ 1.32) | Minimizes voltage overshoot during clamping, reducing risk of MOSFET gate oxide damage in power stages |
| RoHS-compliant HE3 suffix | Indicates AEC-Q101 qualification and JESD 201 Class 2 whisker resistance for long-term solder joint integrity |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed microcontroller power rails in engine control units from load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between VCC and GND to shunt transients exceeding 18.8 V. Use Value: Clamps 600 W surges to ≤30.6 V within nanoseconds, preventing brownout or latch-up of MCU and CAN transceivers. | Use Scenario: Safeguarding analog output lines (e.g., 4–20 mA transmitter) from ESD and field wiring faults in factory automation. IC Role / Device Role / Timing Role: Series-connected TVS on signal path to limit fault voltage before precision DAC or op-amp input stage. Use Value: 1.0 μA leakage at 18.8 V preserves signal accuracy; 30.6 V clamping prevents op-amp saturation during 8 kV contact ESD. |
| Telecom Line Surge Suppression | Consumer Appliance Motor Drive Protection |
Use Scenario: Shielding RS-485 transceiver pins in base station backhaul equipment from lightning-induced surges on twisted-pair cabling. IC Role / Device Role / Timing Role: Bidirectional protection not applicable; P6KE22AHE3/54 used on DC bias rail feeding isolated RS-485 driver IC. Use Value: 20.9–23.1 V breakdown ensures no conduction during normal 24 V bias, while 30.6 V clamping protects driver IC's internal LDO. | Use Scenario: Guarding gate drivers in BLDC motor inverters against shoot-through-inducing voltage spikes during MOSFET switching. IC Role / Device Role / Timing Role: Mounted across bootstrap capacitor supply to clamp ringing above 18.8 V. Use Value: 100 A IFSM withstands repetitive commutation spikes; 20 °C/W RθJL enables direct lead-to-copper thermal path for surge dissipation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ22A | Same VBR range (22.2–24.5 V), but SMC package (higher IPPM = 29.1 A, same PPPM = 600 W), surface-mount | Requires PCB rework for SMT layout; better suited for space-constrained designs with automated assembly | Select SMBJ22A when board real estate is limited and reflow compatibility is required; P6KE22AHE3/54 remains optimal for through-hole prototyping or high-vibration environments. |
| 1.5KE22A | Same DO-201AE package, identical VBR/VC, but higher PPPM = 1500 W and larger physical size; commercial grade only (no AEC-Q101) | Lacks automotive qualification; suitable for industrial mains-powered equipment where higher surge margin is needed | Choose 1.5KE22A for non-automotive applications demanding >600 W headroom; retain P6KE22AHE3/54 where AEC-Q101 compliance and DO-15 footprint are mandatory. |
Compared with SMBJ22A and 1.5KE22A, P6KE22AHE3/54 uniquely balances AEC-Q101 qualification, DO-15 mechanical robustness, and precise 18.8 V stand-off for 24 V system rails-making it the preferred choice for automotive Tier-1 suppliers requiring traceable, vibration-resistant through-hole TVS protection.

FAQ
What is the clamping voltage of P6KE22AHE3/54 at its rated peak pulse current?
The P6KE22AHE3/54 has a maximum clamping voltage (VC) of 30.6 V at its peak pulse current (IPPM) of 19.6 A, measured using the standard 10/1000 μs waveform. This value ensures downstream components like microcontrollers or transceivers experience no more than 30.6 V during a 600 W transient event. The clamping performance is validated per Figure 1 and Table 1 in Vishay Document 88369.
Is P6KE22AHE3/54 suitable for automotive applications?
Yes, P6KE22AHE3/54 is AEC-Q101 qualified and explicitly rated for automotive use, including engine control, body electronics, and sensor modules. Its HE3 suffix confirms compliance with JESD 201 Class 2 whisker testing and RoHS requirements. The device operates from –55 °C to +175 °C junction temperature, meeting under-hood thermal demands. Vishay specifies this qualification in the Mechanical Data and Notes sections of Document 88369.
How does the P6KE22AHE3/54 differ from the P6KE22A-E3/54 variant?
The P6KE22AHE3/54 differs from P6KE22A-E3/54 solely in qualification level: the "H" prefix denotes AEC-Q101 qualification, while the base E3 version is commercial grade only. Both share identical electrical specs (VBR, VC, PPPM), DO-15 package, and RoHS compliance. The HE3 variant undergoes additional stress testing per AEC-Q101, including temperature cycling and highly accelerated life testing, making it mandatory for automotive production.
What is the maximum reverse leakage current for P6KE22AHE3/54 at its stand-off voltage?
The maximum reverse leakage current (ID) for P6KE22AHE3/54 is 1.0 μA at its stand-off voltage (VWM) of 18.8 V, measured at 25 °C ambient. This low leakage preserves signal integrity in high-impedance sensor circuits and avoids unnecessary power loss in always-on automotive modules. The value is specified in the Electrical Characteristics table of Vishay Document 88369.
Can P6KE22AHE3/54 be used in bidirectional configurations?
No, P6KE22AHE3/54 is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. For bidirectional protection, Vishay offers the CA-suffixed variants (e.g., P6KE22CA). Using P6KE22AHE3/54 in reverse-biased configurations risks permanent failure, as it is not characterized for symmetrical clamping. The datasheet explicitly states that bidirectional types require the CA suffix and have different VBR ranges.
