Product details
Overview
P6KA22HE3/54 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 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 supplies and industrial sensor interfaces.
For engineers reviewing the P6KA22HE3/54 datasheet, P6KA22HE3/54 pinout, P6KA22HE3/54 application, or P6KA22HE3/54 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 architecture provides forward conduction only during reverse overvoltage events, enabling precise clamping without interfering with normal DC bias paths.
Rated for TJ = 185 °C and qualified to AEC-Q101, the P6KA22HE3/54 supports automotive under-hood applications where thermal stability and long-term surge endurance are critical. Its low incremental surge resistance and fast response time ensure effective suppression of inductive switching transients and ESD-like pulses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 19.8 V / 24.2 V - defines reliable turn-on threshold range for transient clamping |
| VWM | 17.8 V - maximum continuous reverse operating voltage before leakage rises significantly |
| VC @ IPPM | 31.9 V - clamped voltage during 18.8 A 10/1000 μs surge, limiting downstream stress |
| PPPM | 600 W - peak power handling capability under standardized surge waveform |
| IPPM | 18.8 A - corresponding peak current at VC, used for PCB trace and fuse sizing |
| TJ max. | 185 °C - enables operation in high-temperature environments such as engine control units |
| Polarity | Unidirectional - blocks reverse voltage until breakdown, conducts forward during clamping |

| Passivated anisotropic rectifier structure | Reduces parameter drift over lifetime and improves surge-to-surge consistency |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump transients up to 35 V and inductive switching spikes. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and chassis ground to clamp surges before they reach LDOs or microcontrollers. Use Value: Withstands 600 W surges and maintains VC ≤ 31.9 V, ensuring downstream components operate within absolute maximum ratings. | Use Scenario: Shielding analog output lines (e.g., 4–20 mA current loops) from ESD and field-induced transients in factory automation. IC Role / Device Role / Timing Role: TVS mounted across signal and return path to shunt fast transients while preserving low-leakage signal integrity. Use Value: 1.0 μA max reverse leakage at VWM avoids loading precision circuits; fast response prevents latch-up in connected ADCs. |
| Consumer Power Adapter Input Stage | Telecom DC Power Interface |
Use Scenario: Safeguarding AC/DC adapter primary-side rectifier outputs against line surges and cross-talk from adjacent switching stages. IC Role / Device Role / Timing Role: Unidirectional TVS on DC bus to absorb energy from transformer leakage inductance and MOSFET turn-off spikes. Use Value: 75 A IFSM rating supports high-energy single-event surges; DO-15 package allows through-hole mounting in cost-sensitive designs. | Use Scenario: Protecting -48 V telecom power feeds from lightning-induced surges entering via outdoor cabling. IC Role / Device Role / Timing Role: TVS placed at power entry point to clamp common-mode transients before distribution to shelf controllers and interface cards. Use Value: 185 °C rating ensures stable performance in sealed, fanless telecom enclosures; UL 94 V-0 molding compound meets fire safety 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-E3/5A | Same VBR range (20.9–23.1 V), but 400 W PPPM and SMA package (surface-mount) | Lower power handling; suited for space-constrained PCBs where 600 W is not required | Select when board area is limited and surge energy is below 400 W; verify thermal pad layout for SMA |
| 1.5KE22A | Same VBR (19.8–24.2 V), 1500 W PPPM, DO-201 package (larger than DO-15) | Higher surge capacity but larger footprint and higher VC (35.5 V) | Choose for legacy designs requiring higher energy absorption; confirm mechanical fit and clamping margin |
Compared with SMAJ22A-E3/5A and 1.5KE22A, the P6KA22HE3/54 delivers optimal balance of 600 W surge capability, compact DO-15 form factor, AEC-Q101 qualification, and 31.9 V clamping - making it ideal for new automotive and industrial designs where reliability, size, and thermal robustness are jointly prioritized.

FAQ
What is the maximum clamping voltage of the P6KA22HE3/54 under standard test conditions?
The P6KA22HE3/54 has a maximum clamping voltage (VC) of 31.9 V when subjected to its rated peak pulse current (IPPM = 18.8 A) using the 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and ensures predictable overvoltage limiting for downstream circuitry. The P6KA22HE3/54 maintains this clamping performance across its full operating temperature range.
Is the P6KA22HE3/54 suitable for automotive applications?
Yes, the P6KA22HE3/54 is AEC-Q101 qualified and rated for junction temperatures up to +185 °C, making it suitable for under-hood and powertrain-related automotive applications. Its construction meets automotive reliability requirements including thermal cycling, humidity bias, and surge endurance testing. The P6KA22HE3/54 is explicitly listed in Vishay's AEC-Q101 qualified product list for transient suppression.
What does the "HE3/54" suffix indicate in P6KA22HE3/54?
The "HE3" suffix denotes RoHS-compliant, matte tin-plated leads that meet J-STD-002 and JESD 22-B102 solderability standards, plus JESD 201 Class 2 whisker resistance. The "/54" indicates packaging in 13-inch paper tape and reel with a base quantity of 4000 units. This configuration applies directly to the P6KA22HE3/54 and is confirmed in Vishay's official ordering information table.
How does the P6KA22HE3/54 differ from the P6KA22A variant?
The P6KA22HE3/54 corresponds to the standard P6KA22 variant (VBR min/max = 19.8 V / 24.2 V), whereas P6KA22A has tighter VBR tolerance (20.9 V / 23.1 V). Both share identical package, power rating, clamping voltage, and qualification status. The P6KA22HE3/54 is selected when broader VBR tolerance is acceptable and cost optimization is prioritized.
What is the reverse leakage current specification for the P6KA22HE3/54 at its stand-off voltage?
At VWM = 17.8 V and TA = 25 °C, the P6KA22HE3/54 exhibits a maximum reverse leakage current (ID) of 1.0 μA. At elevated temperature (TJ = 150 °C), leakage remains ≤ 5.0 μA - a critical parameter for low-power sensor and battery-backed systems where standby current must be minimized. This value is verified in Vishay's Electrical Characteristics table for P6KA22.
