Product details
Overview
P6KE22C-E3/73 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode designed for clamping voltage transients on signal or power lines. It features a 22 V breakdown voltage (VBR min/max = 20.9–23.1 V), 30.6 V maximum clamping voltage at 19.6 A peak pulse current, 600 W peak pulse power rating (10/1000 µs), and DO-204AC (DO-15) package. It protects MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems against ESD and inductive switching surges.
For engineers reviewing the P6KE22C-E3/73 datasheet, P6KE22C-E3/73 pinout, P6KE22C-E3/73 application, or P6KE22C-E3/73 equivalent, this page delivers verified electrical parameters, bi-directional clamping behavior, thermal resistance (RθJA = 75 °C/W), RoHS-compliant matte tin plating, and AEC-Q101 qualification status - all critical for surge protection design validation and BOM selection.
Technical Context
This bi-directional TVS operates symmetrically in both polarities, with identical VBR, IPPM, and VC specifications in forward and reverse directions. Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, ensuring reliable clamping before downstream components experience overvoltage stress.
The device is rated for 600 W peak pulse power under 10/1000 µs waveform at TA = 25 °C, derated linearly above 25 °C per Fig. 2, and supports repetitive surge duty cycles up to 0.01 %. Its 175 °C maximum junction temperature and 20 °C/W junction-to-lead thermal resistance support robust thermal management in compact PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 20.9 V / 23.1 V at IT = 1.0 mA - defines precise voltage threshold where clamping initiates in either polarity |
| VWM | 18.8 V - maximum continuous working voltage; system operating voltage must stay below this to avoid leakage |
| VC @ IPPM | 30.6 V at 19.6 A - clamped voltage seen by protected circuit during worst-case 10/1000 µs transient |
| PPPM | 600 W - peak surge energy absorption capability without failure, enabling protection against IEC 61000-4-5 Level 4 surges |
| IPPM | 19.6 A - maximum non-repetitive surge current the device safely diverts away from sensitive nodes |
| RθJA | 75 °C/W - thermal resistance from junction to ambient; dictates required board copper area for sustained power dissipation |
| TJ max | +175 °C - maximum junction temperature; allows operation in under-hood automotive or high-temperature industrial environments |
Pinout & Package
Package: DO-204AC (DO-15), axial leaded, molded epoxy case meeting UL 94 V-0. Matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards. No polarity marking - bi-directional symmetry eliminates cathode/anode orientation concerns during placement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bi-directional surge conduction path | Either terminal serves as input/output; no fixed polarity - connects across protected line and ground (or between differential lines) |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables <1 ns response time and stable VBR tolerance over lifetime, critical for sub-microsecond ESD events |
| 600 W peak pulse power (10/1000 µs) | Supports IEC 61000-4-5 4th-level surge immunity testing without derating or parallel devices |
| AEC-Q101 qualified (HE3 suffix variant) | P6KE22C-E3/73 shares platform with AEC-Q101 qualified P6KE22CHE3/73 - validated for automotive powertrain and body electronics |
| Low clamping ratio (VC/VBR ≈ 1.32) | Minimizes overvoltage stress on protected ICs - e.g., keeps 3.3 V or 5 V logic within safe margin during clamping |
| RoHS-compliant, matte tin plating | Ensures reliable solder joint formation and whisker resistance (JESD 201 Class 1A) for long-term field reliability |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ22CA | Same VBR range (20.9–23.1 V), but SMC (DO-214AB) package - 30 % smaller footprint, higher IPPM (32.4 A), lower RθJA (50 °C/W) | Better suited for space-constrained designs and higher-repetition surges; requires re-layout due to different pad geometry | Select SMBJ22CA when board area is limited or thermal performance under repeated transients is critical. |
| 1.5KE22CA | Same DO-204AC package and VBR, but 1500 W peak power (10/1000 µs); larger die, higher VC (35.5 V), higher IPPM (42.5 A) | Used where single-event surge energy exceeds 600 W - e.g., AC mains input stages or telecom central office equipment | Choose 1.5KE22CA only if system-level surge testing requires >600 W headroom; otherwise P6KE22C-E3/73 offers optimal cost/performance balance. |
Compared with SMBJ22CA and 1.5KE22CA, P6KE22C-E3/73 delivers the best trade-off of standardized DO-15 compatibility, proven AEC-Q101 platform heritage, and sufficient 600 W surge capacity for most automotive and industrial signal-line applications - without over-engineering board space or thermal budget.

FAQ
What is the polarity configuration of P6KE22C-E3/73?
P6KE22C-E3/73 is a bi-directional TVS diode with symmetrical electrical characteristics in both forward and reverse directions. It has no cathode marking and functions identically regardless of terminal orientation - making it ideal for AC-coupled lines, differential buses, or any application where polarity reversal is possible. This behavior is confirmed in the Vishay datasheet section "Devices for Bi-Direction Applications" and electrical tables showing identical VBR, VC, and IPPM values for both polarities.
Does P6KE22C-E3/73 meet automotive qualification standards?
P6KE22C-E3/73 itself carries the commercial-grade E3 suffix and is RoHS compliant, but it shares the same die and construction as the AEC-Q101 qualified P6KE22CHE3/73 variant (HE3 suffix). The datasheet explicitly states "P6KE220A to P6KE540A and P6KE220CA to P6KE440CA for commercial grade only", confirming P6KE22C-E3/73 is not AEC-Q101 certified. For automotive use, specify P6KE22CHE3/73 - the P6KE22C-E3/73 is intended for industrial and consumer applications with less stringent qualification requirements.
What is the maximum clamping voltage of P6KE22C-E3/73 under surge conditions?
The maximum clamping voltage (VC) of P6KE22C-E3/73 is 30.6 V, measured at its rated peak pulse current (IPPM) of 19.6 A using a 10/1000 µs waveform. This value represents the highest voltage that will appear across the protected circuit during a worst-case transient event. It is derived directly from the "ELECTRICAL CHARACTERISTICS" table in the Vishay datasheet (Document Number: 88369), row labeled "(+)P6KE22CA", and is critical for verifying that downstream ICs remain within their absolute maximum voltage ratings.
Can P6KE22C-E3/73 be used in place of a unidirectional TVS like P6KE22A?
No - P6KE22C-E3/73 and P6KE22A serve fundamentally different circuit roles. P6KE22C-E3/73 is bi-directional and lacks polarity marking, while P6KE22A is unidirectional with a cathode band and conducts only in reverse bias. Substituting one for the other risks forward conduction, excessive leakage, or failure to clamp in one polarity. The "C" suffix explicitly denotes bi-directional function per Vishay's naming convention, and the datasheet confirms separate parameter tables for "A" (uni) and "CA" (bi) variants - confirming they are not interchangeable without schematic and layout revision.
What is the thermal resistance and power derating behavior of P6KE22C-E3/73?
P6KE22C-E3/73 has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-lead (RθJL) of 20 °C/W. Its steady-state power dissipation (PD) is rated at 5.0 W on an infinite heatsink at TL = 75 °C, but must be linearly derated above 25 °C ambient per Figure 2 in the datasheet - reaching zero at 175 °C. This derating curve is essential for determining safe continuous power handling in enclosed or high-temperature environments, and the 75 °C/W value informs minimum copper pour area needed on PCB for thermal management.
