Product details
Overview
P6KA22AHE3/54 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 20.9 V to 23.1 V breakdown voltage (VBR), 18.8 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 μs), 19.6 A peak pulse current (IPPM), and clamps to ≤30.6 V at rated surge - deployed on automotive ECUs, industrial sensor interfaces, and DC power rails.
For engineers reviewing the P6KA22AHE3/54 datasheet, P6KA22AHE3/54 pinout, P6KA22AHE3/54 application, or P6KA22AHE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, 185 °C junction rating, DO-15 package compatibility, and verified clamping performance under repetitive 10/1000 μs transients per IEC 61000-4-5.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology with optimized junction passivation for stable high-temperature operation up to TJ = 185 °C. Its unidirectional polarity enables integration into DC-biased circuits where reverse conduction must be blocked until clamping threshold is exceeded.
It delivers 600 W peak pulse power with low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of inductive switching spikes and lightning-induced surges. Clamping voltage is specified at 30.6 V under 19.6 A (10/1000 μs), ensuring reliable protection margin for 24 V nominal systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ22A | Lower peak pulse power (400 W), same DO-214AC package, VBR = 24.4–26.9 V | Not AEC-Q101 qualified; limited to commercial/industrial use | Select when cost sensitivity outweighs automotive qualification and 600 W surge headroom |
| 1.5KE22A | Higher VC (35.5 V), larger DO-201AD package, same 600 W rating, not AEC-Q101 qualified | Larger footprint and higher clamping voltage reduce suitability for space-constrained 24 V systems | Choose only if legacy board layout requires DO-201AD or higher VC margin is acceptable |
Compared with SMAJ22A and 1.5KE22A, P6KA22AHE3/54 uniquely combines AEC-Q101 qualification, DO-15 form factor, 600 W rating, and 30.6 V clamping - making it the preferred choice for new automotive and high-reliability industrial designs requiring compact, qualified TVS protection.

FAQ
What is the maximum clamping voltage of the P6KA22AHE3/54 under rated surge conditions?
The P6KA22AHE3/54 has a maximum clamping voltage (VC) of 30.6 V when subjected to its rated 19.6 A peak pulse current (IPPM) using the standard 10/1000 μs waveform. This value is measured at TA = 25 °C and guarantees that protected circuitry remains below critical overvoltage thresholds during surge events. The P6KA22AHE3/54 maintains this clamping performance across its full operating temperature range.
Is the P6KA22AHE3/54 suitable for automotive applications?
Yes, the P6KA22AHE3/54 is AEC-Q101 qualified and rated for operation up to +185 °C junction temperature, making it suitable for under-hood and chassis-mounted automotive applications such as body control modules, ADAS sensor interfaces, and power distribution units. Its DO-15 package and unidirectional polarity align with common automotive PCB layouts. The P6KA22AHE3/54 meets stringent reliability requirements including temperature cycling and high-temperature reverse bias testing.
What does the "HE3/54" suffix indicate in P6KA22AHE3/54?
The "HE3" suffix denotes RoHS-compliant construction with matte tin-plated leads and JESD 201 Class 2 whisker resistance; "54" specifies the preferred packaging code - 4000 units per 13-inch paper tape and reel. This packaging format ensures automated placement compatibility and traceable lot control. The P6KA22AHE3/54 is supplied in this configuration to support high-volume SMT assembly without lead finish or moisture sensitivity concerns.
How does the P6KA22AHE3/54 differ from the non-A version (P6KA22)?
The P6KA22AHE3/54 has tighter VBR tolerance (20.9–23.1 V) versus P6KA22 (19.8–24.2 V), resulting in more consistent clamping onset and reduced unit-to-unit variation in surge response. Both share identical power ratings and package, but the "A" variant is optimized for applications requiring tighter voltage control - such as precision 24 V systems where margin between VWM and VBR must be minimized. The P6KA22AHE3/54 also carries the HE3/54 packaging specification.
What is the reverse leakage current of the P6KA22AHE3/54 at maximum operating temperature?
At TJ = 150 °C and VWM = 18.8 V, the P6KA22AHE3/54 exhibits a maximum reverse leakage current (ID) of 1000 μA - confirmed in the Vishay datasheet (Document Number 88368). At room temperature (25 °C), leakage is ≤1.0 μA. This controlled leakage ensures minimal power loss in standby mode while maintaining fast avalanche response. The P6KA22AHE3/54 retains stable leakage behavior across its full -65 °C to +185 °C operating range.
