Product details
Overview
P6KA20HE3/54 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for primary overvoltage protection on DC power rails and signal lines. It features a 18.0–22.0 V breakdown voltage (VBR), 16.2 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 µs), 20.6 A peak pulse current (IPPM), and clamps to 29.1 V at rated surge, enabling robust protection of MOSFETs and ICs in automotive power supplies.
For engineers reviewing the P6KA20HE3/54 datasheet, P6KA20HE3/54 pinout, P6KA20HE3/54 application, or P6KA20HE3/54 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, DO-204AC package dimensions, clamping behavior under surge, and direct alternatives for circuit-level ESD/surge hardening in high-reliability embedded systems.
Technical Context
This TVS operates as a silicon avalanche diode with passivated anisotropic rectifier technology, optimized for fast response (<1 ns) and low incremental surge resistance. Its unidirectional polarity and 185 °C maximum junction temperature support operation in under-hood automotive environments and industrial power converters where thermal stability is critical.
The device complies with ANSI/IEEE C62.35 for transient suppression and is rated for repetitive 10/1000 µs surges at 0.01% duty cycle. Clamping voltage is specified at IPPM = 20.6 A, and leakage remains ≤1.0 µA at VWM = 16.2 V up to 150 °C - confirming suitability for low-power sensor rail protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 18.0 V / 22.0 V - defines minimum voltage at which avalanche conduction begins reliably; ensures no false triggering below 18.0 V under normal operation |
| VWM | 16.2 V - maximum continuous reverse working voltage; sets safe operating margin below breakdown for 12 V nominal systems |
| VC @ IPPM | 29.1 V - clamping voltage during 20.6 A surge; determines maximum stress imposed on downstream protected ICs |
| PPPM | 600 W - peak pulse power handling (10/1000 µs); supports IEC 61000-4-5 Level 4 surge immunity testing |
| TJ max. | +185 °C - enables use in engine control units and power inverters without derating in high-ambient zones |
| AEC-Q101 | Qualified - confirms reliability for automotive electronics per stress test requirements including HTGB, HTRB, and TCT |
Pinout & Package
Package: DO-204AC (DO-15), axial leaded, epoxy-molded case with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102. Cathode indicated by color band. Meets UL 94 V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in unidirectional TVS configuration |
| Cathode | Avalanche conduction terminal | Connected to protected line (e.g., 12 V rail); conducts surge current to ground when VAK exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| Passivated anisotropic rectifier structure | Enables stable VBR tolerance and low leakage across temperature without surface degradation |
| 185 °C junction rating | Supports uninterrupted operation in under-hood ECUs and motor drive modules without thermal shutdown |
| 600 W peak pulse power (10/1000 µs) | Withstands ISO 7637-2 Pulse 5a/b surges and IEC 61000-4-5 Combination Wave (1.2/50 µs + 8/20 µs) |
| AEC-Q101 qualification | Validates long-term reliability for automotive applications including HTGB, HTRB, and temperature cycling |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage overshoot during transients, reducing stress on downstream MOSFET gate oxides and logic inputs |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed microcontroller power inputs against load dump and alternator transients in body control modules. IC Role / Device Role / Timing Role: Unidirectional TVS placed between VIN and GND, clamping surges before they reach LDO input. Use Value: Limits peak voltage to 29.1 V during 20.6 A transients, preventing damage to 33 V-rated input stages and ensuring system reset integrity. | Use Scenario: Shielding analog output lines (e.g., 4–20 mA transmitter) from ESD and inductive switching noise in factory automation PLCs. IC Role / Device Role / Timing Role: TVS mounted at connector entry point, shunting fast transients (<1 ns rise) to chassis ground. Use Value: Sub-1 µA leakage at 16.2 V preserves signal accuracy; 29.1 V clamping prevents op-amp saturation and ADC overrange errors. |
| Consumer Power Adapter Input Stage | Telecom DC Feeder Line Protection |
Use Scenario: Safeguarding AC/DC adapter secondary-side 12 V outputs against cross-coupled surges from nearby switching circuits. IC Role / Device Role / Timing Role: Primary overvoltage clamp on regulated output rail, upstream of USB-PD controller. Use Value: 600 W rating absorbs multiple repetitive 10/1000 µs events without degradation; DO-15 package allows through-hole mounting in high-vibration environments. | Use Scenario: Protecting -48 V telecom power distribution boards from lightning-induced surges entering via outdoor cable runs. IC Role / Device Role / Timing Role: Unidirectional TVS on negative rail, referenced to system ground, absorbing positive-going transients. Use Value: 185 °C rating ensures performance in sealed outdoor cabinets; 1.0 µA leakage at 16.2 V avoids drain on backup batteries. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ20A | DO-214AA package (SMB), 20 V VWM, 33.2 V VC @ 17.1 A, same 600 W rating | Surface-mount footprint; lower thermal resistance but requires PCB rework for through-hole legacy designs | Select SMBJ20A only if board layout supports SMD and thermal management leverages copper pour |
| 1.5KE20A | DO-201AD package, 20 V VWM, 32.4 V VC @ 18.5 A, 1500 W rating (10/1000 µs), higher IFSM (100 A) | Larger case size; higher surge capacity but slower response due to higher junction capacitance (~150 pF vs. ~50 pF) | Choose 1.5KE20A for high-energy lightning protection where clamping speed is secondary to energy absorption |
Compared with SMBJ20A and 1.5KE20A, P6KA20HE3/54 offers optimal balance of compact DO-15 through-hole form factor, AEC-Q101 qualification, and low-clamp performance - making it preferred for space-constrained automotive modules requiring validated reliability without SMT conversion.

FAQ
What is the breakdown voltage range for P6KA20HE3/54?
The P6KA20HE3/54 has a guaranteed breakdown voltage (VBR) range of 18.0 V to 22.0 V at 1.0 mA test current, measured per ANSI/IEEE C62.35. This range ensures reliable avalanche initiation while maintaining sufficient margin above its 16.2 V stand-off voltage (VWM) to prevent false triggering in 12 V automotive systems. The specification is validated across temperature and production lots per AEC-Q101 requirements.
Is P6KA20HE3/54 qualified for automotive use?
Yes, P6KA20HE3/54 is AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias (HTGB), high-temperature operating life (HTOL), and temperature cycling (TCT). Its 185 °C maximum junction temperature and DO-204AC package with matte tin leads meet automotive under-hood reliability standards. The HE3 suffix further confirms RoHS compliance and JESD 201 Class 2 whisker resistance.
What is the clamping voltage of P6KA20HE3/54 under surge conditions?
The P6KA20HE3/54 clamps to a maximum of 29.1 V when subjected to its rated peak pulse current of 20.6 A (10/1000 µs waveform). This clamping voltage is measured at the device terminals under standardized surge conditions and defines the upper voltage limit imposed on protected circuitry - critical for ensuring compatibility with 33 V-tolerant IC inputs and MOSFET gate oxide ratings.
Does P6KA20HE3/54 have unidirectional or bidirectional polarity?
P6KA20HE3/54 is unidirectional only, with cathode denoted by a color band on the DO-204AC package. It conducts surge current only when the anode is negative relative to the cathode - making it suitable for DC rail protection where polarity is fixed. Bidirectional variants (e.g., P6K20A) are separate part numbers and not interchangeable with P6KA20HE3/54.
What package type does P6KA20HE3/54 use, and what are its key mechanical features?
P6KA20HE3/54 uses the DO-204AC (DO-15) axial-leaded package: 0.375" (9.5 mm) body length, 0.140" (3.6 mm) diameter, matte tin-plated leads solderable per J-STD-002, and UL 94 V-0 rated epoxy molding compound. The HE3 suffix indicates RoHS compliance and JESD 201 Class 2 whisker resistance, supporting high-reliability assembly in automotive and industrial manufacturing.
