Product details
Overview
P4KA22HE3/54 from Vishay General Semiconductor is a unidirectional automotive-grade transient voltage suppressor (TVS) diode in DO-204AL (DO-41) package, with 19.8 V to 24.2 V breakdown voltage (VBR), 400 W peak pulse power (10/1000 µs), 1.5 W steady-state power dissipation, 12.5 A peak pulse current (IPPM), and 31.9 V clamping voltage (VC) at rated surge. It protects MOSFETs, ICs, and sensor signal lines in automotive powertrain and body electronics against inductive switching transients.
For engineers reviewing the P4KA22HE3/54 datasheet, P4KA22HE3/54 pinout, P4KA22HE3/54 application, or P4KA22HE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, 185 °C max junction temperature, 0.092 %/°C VBR temperature coefficient, RoHS-compliant HE3 suffix with JESD201 Class 2 whisker resistance, and DO-41 mechanical compatibility for through-hole board-level surge protection.
Technical Context
The P4KA22HE3/54 employs Vishay's patented PAR® construction for stable clamping under repetitive surge stress and high-temperature operation up to 185 °C. Its unidirectional configuration provides forward conduction during overvoltage events while maintaining low leakage (<1 µA at 17.8 V) and fast response time typical of silicon avalanche devices.
Designed for automotive environments, it meets AEC-Q101 stress test requirements and delivers consistent 400 W pulse power handling with 10/1000 µs waveform at 0.01 % duty cycle. Its low incremental surge resistance ensures minimal voltage overshoot during transient suppression in 12 V and 24 V vehicle electrical systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 19.8 V / 24.2 V - defines reliable avalanche initiation range under 10 mA test current |
| VC @ IPPM | 31.9 V - maximum clamped voltage during 12.5 A 10/1000 µs surge, limiting downstream device stress |
| PPPM | 400 W - peak transient energy absorption capability per ANSI/IEEE C62.35 standard |
| IFSM | 40 A - withstands 8.3 ms half-sine surge without failure, critical for load-dump immunity |
| TJ max | +185 °C - enables placement near hot engine-control components without derating loss |
| VWM | 17.8 V - maximum continuous reverse operating voltage before significant leakage begins |
| αVBR | 0.092 %/°C - quantifies VBR drift with temperature, essential for precision clamp design |

Use Value: 1.0 µA leakage at 17.8 V preserves sensor accuracy; 31.9 V clamping prevents op-amp saturation in 5 V signal chains. |
| Body Control Module (BCM) Relay Drive Protection | Automotive Lighting Circuit Surge Suppression |
Use Scenario: Shields MOSFET gate drivers and logic inputs from inductive kickback when controlling door locks, window motors, or HVAC actuators. IC Role / Device Role / Timing Role: Mounted across relay coil or motor winding to absorb flyback energy and prevent controller damage. Use Value: 400 W PPPM rating handles repeated 100–200 mJ pulses; DO-41 axial form factor fits compact relay PCB footprints. | Use Scenario: Safeguards LED driver ICs and current-sense resistors in headlamp and tail lamp assemblies exposed to alternator ripple and jump-start spikes. IC Role / Device Role / Timing Role: Connected between LED string anode and 12 V supply to clamp positive-going transients above 17.8 V. Use Value: 185 °C TJ max allows mounting near heat-generating LED arrays; 0.092 %/°C αVBR ensures stable clamping across ambient range. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ22A-E3/52 (Vishay) | Surface-mount SMB package; 22 V nominal VBR; same 400 W PPPM but lower IFSM (30 A) | Requires rework for SMT assembly; unsuitable for through-hole legacy designs or high-vibration mechanical retention | Select when board space is constrained and automated pick-and-place is available |
| 1.5KE22A (ON Semiconductor) | DO-201 package (larger than DO-41); 22 V VBR; 400 W PPPM; no AEC-Q101 qualification; higher VC (35.5 V) | Lacks automotive qualification; less suitable for safety-critical modules; requires larger PCB footprint | Select for cost-sensitive industrial applications where AEC-Q101 is not mandated |
Compared with SMBJ22A-E3/52 and 1.5KE22A, the P4KA22HE3/54 uniquely combines AEC-Q101 qualification, DO-41 through-hole reliability, and 31.9 V clamping in a single automotive-grade part-enabling drop-in replacement in legacy ECU designs without layout change or qualification retesting.

FAQ
What is the breakdown voltage tolerance for P4KA22HE3/54?
The P4KA22HE3/54 has a specified breakdown voltage (VBR) range of 19.8 V to 24.2 V at 10 mA test current, representing ±10 % tolerance around the nominal 22 V rating. This range is verified per ANSI/IEEE C62.35 and confirmed in the Vishay Document Number 88364, Revision 21-Oct-08, Table on page 2. The P4KA22HE3/54 maintains this specification across its full operating temperature range.
Is P4KA22HE3/54 qualified for automotive use?
Yes, the P4KA22HE3/54 is explicitly AEC-Q101 qualified for automotive applications, as stated in the "Notes" section on page 3 of Vishay Document 88364. Its HE3 suffix denotes high-reliability, automotive-grade construction-including JESD201 Class 2 whisker resistance, solder dip survivability at 260 °C for 40 s, and operation up to +185 °C junction temperature. The P4KA22HE3/54 is intended for under-hood and body electronics where qualification is mandatory.
What is the clamping voltage of P4KA22HE3/54 at its rated peak pulse current?
The P4KA22HE3/54 exhibits a maximum clamping voltage (VC) of 31.9 V at its rated peak pulse current (IPPM) of 12.5 A, measured using the standardized 10/1000 µs waveform. This value is listed in the Electrical Characteristics table on page 2 of Vishay Document 88364 and defines the upper voltage limit imposed on protected circuitry during surge events. The P4KA22HE3/54 achieves this with low incremental surge resistance inherent to its PAR® structure.
Can P4KA22HE3/54 be used in bidirectional configurations?
No, the P4KA22HE3/54 is available in uni-directional polarity only, as clearly stated in the FEATURES section on page 1 of Vishay Document 88364. It functions as a single-junction avalanche diode with cathode marked by a color band; bidirectional protection requires two devices or a dedicated bi-directional TVS such as the P4SMA22HE3/A. The P4KA22HE3/54 must be oriented correctly in-circuit to conduct only during reverse overvoltage conditions.
What packaging format is supplied for P4KA22HE3/54?
The P4KA22HE3/54 is supplied in 13-inch diameter paper tape and reel packaging, with a base quantity of 5500 units per reel (package code "54"), as specified in the ORDERING INFORMATION section on page 3 of Vishay Document 88364. This format supports automated through-hole insertion equipment and is compatible with standard reel-handling systems used in automotive electronics manufacturing. The P4KA22HE3/54 HE3 suffix confirms RoHS compliance and high-reliability plating.
