Product details
Overview
P6KA22HE3/73 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 19.8 V to 24.2 V breakdown voltage (VBR), 17.8 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 μs), 18.8 A peak pulse current, and 31.9 V maximum clamping voltage at rated current - deployed in automotive power supply rails and industrial sensor interfaces.
For engineers reviewing the P6KA22HE3/73 datasheet, P6KA22HE3/73 pinout, P6KA22HE3/73 application, or P6KA22HE3/73 equivalent, key selection criteria include unidirectional polarity, DO-204AC (DO-15) package compatibility, AEC-Q101 qualification, 185 °C junction temperature rating, and clamping performance under 10/1000 μs surge conditions.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology with junction passivation optimized for high-reliability operation. Its unidirectional configuration provides low-leakage reverse blocking up to 17.8 V and rapid clamping response during transients induced by inductive switching or ESD events.
The device is rated for repetitive 600 W pulse dissipation (10/1000 μs), exhibits 0.092 %/°C temperature coefficient of VBR, and supports surge currents up to 75 A (8.3 ms half-sine). It meets JESD 22-B106 solderability and JESD 201 Class 2 whisker resistance requirements.

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-E3/5AT | Same DO-214AC (SMA) package; 22 V nominal VBR; 400 W PPPM; lower surge rating | Lower power handling limits use to sub-10 A surge environments; not AEC-Q101 qualified | Select when board space allows SMA footprint and automotive qualification is not required |
| 1.5KE22A | DO-201AD package; same 22 V VBR; 1500 W PPPM; higher IPPM (68.2 A) | Larger footprint and higher clamping voltage (35.5 V); suited for non-automotive industrial mains protection | Choose for higher-energy surge immunity where PCB layout accommodates larger case size |
Compared with P6KA22HE3/73, SMAJ22A-E3/5AT offers smaller size but reduced surge margin and no automotive qualification, while 1.5KE22A delivers higher energy handling at the cost of larger footprint and elevated clamping - making P6KA22HE3/73 optimal for space-constrained, AEC-Q101–mandated 12 V systems.

FAQ
What is the breakdown voltage range of the P6KA22HE3/73?
The P6KA22HE3/73 has a specified breakdown voltage (VBR) range of 19.8 V to 24.2 V at 1.0 mA test current. This range ensures consistent clamping initiation across manufacturing lots and temperature extremes, and is verified per ANSI/IEEE C62.35 standards. The P6KA22HE3/73 maintains this specification under operating junction temperatures from -65 °C to +185 °C.
Is the P6KA22HE3/73 suitable for automotive applications?
Yes, the P6KA22HE3/73 is AEC-Q101 qualified and rated for TJ up to +185 °C, making it suitable for under-hood and powertrain applications. Its DO-204AC package, matte tin plating, and JESD 201 Class 2 whisker resistance further support automotive reliability requirements. The P6KA22HE3/73 is explicitly listed in Vishay's PAR® automotive-grade TVS portfolio.
What is the maximum clamping voltage of the P6KA22HE3/73 at its rated peak pulse current?
The P6KA22HE3/73 exhibits a maximum clamping voltage (VC) of 31.9 V at its rated peak pulse current (IPPM) of 18.8 A, measured using the 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and directly limits the voltage seen by downstream components during surge events.
Does the P6KA22HE3/73 have bidirectional or unidirectional polarity?
The P6KA22HE3/73 is unidirectional only, with polarity marked by a cathode band. It blocks reverse voltage up to 17.8 V (VWM) and clamps positive transients on the cathode side. Bidirectional variants (e.g., P6SMB22AH) are separate part numbers - the P6KA22HE3/73 is not interchangeable with them without circuit redesign.
What package type does the P6KA22HE3/73 use, and what are its key mechanical attributes?
The P6KA22HE3/73 uses the DO-204AC (DO-15) axial package: 9.5 mm body length, 3.6 mm diameter, matte tin-plated leads, UL 94 V-0 compliant epoxy molding. Lead spacing is 7.6 mm minimum, and it withstands solder dip at 275 °C for 10 seconds per JESD 22-B106 - all confirmed in Vishay document 88368 for the P6KA22HE3/73.
