Product details
Overview
P6KE220A-E3/73 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a 209 V minimum breakdown voltage (VBR), 185 V maximum standoff voltage (VWM), 328 V clamping voltage (VC) at 1.8 A peak pulse current, 600 W peak pulse power rating with 10/1000 µs waveform, and operates across -55 °C to +175 °C junction temperature range - deployed in automotive power supply inputs and industrial sensor interface protection.
For engineers reviewing the P6KE220A-E3/73 datasheet, P6KE220A-E3/73 pinout, P6KE220A-E3/73 application, or P6KE220A-E3/73 equivalent, key selection criteria include clamping performance under 10/1000 µs surge, thermal resistance (RθJL = 20 °C/W), unidirectional polarity marking, DO-15 package mechanical compatibility, and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
This device functions as a voltage-clamped shunt protector: when transient voltage exceeds VWM (185 V), it avalanches into low-impedance conduction, limiting downstream voltage to ≤328 V at 1.8 A. Its glass-passivated junction ensures stable VBR tolerance (±5 %) and fast response time (<1 ns), critical for protecting MOSFET gates and microcontroller I/O against ESD and inductive switching spikes.
Thermal design relies on lead-to-case conduction (RθJL = 20 °C/W); derating begins above 25 °C ambient, with full power (5.0 W) only sustainable at TL = 75 °C. The DO-15 package supports manual or wave soldering (275 °C, 10 s max), and matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 185 V maximum - defines highest continuous DC or RMS voltage the device blocks without conduction |
| VBR (min/max) | 209 V / 231 V at 1.0 mA - ensures reliable avalanche initiation within ±5 % tolerance for predictable clamping onset |
| VC @ IPPM | 328 V at 1.8 A (10/1000 µs) - maximum voltage seen by protected circuit during worst-case surge event |
| PPPM | 600 W - surge energy handling capacity per single 10/1000 µs pulse, enabling robust protection against lightning-induced transients |
| RθJL | 20 °C/W - enables thermal management via PCB copper pour or heatsink attachment to leads for sustained operation |
| TJ range | -55 °C to +175 °C - supports deployment in under-hood automotive and high-temperature industrial environments |
| ID @ VWM | 1.0 µA maximum - guarantees negligible leakage current in standby, preserving battery life in always-on systems |
Pinout & Package
DO-15 (DO-204AC) molded epoxy package with axial leads; cathode indicated by color band on body. Leads are matte tin-plated, compliant with J-STD-002 solderability and JESD 201 Class 1A whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference node for unidirectional clamping | Connected to ground or lower-potential rail; defines direction of surge current flow during avalanche |
| Cathode | Protected line connection point | Connected to input rail (e.g., 24 V supply); color band identifies this terminal for correct PCB orientation |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures stable VBR over lifetime and temperature, eliminating parameter drift in harsh environments |
| 600 W peak pulse power (10/1000 µs) | Supports IEC 61000-4-5 Level 4 surge immunity (4 kV line-earth) without degradation |
| AEC-Q101 qualified (E3 suffix variant) | Validated for automotive powertrain and body electronics per stress-test requirements including HTOL and TC |
| Low clamping ratio (VC/VBR ≈ 1.43) | Minimizes overvoltage margin between clamping and protected IC's absolute maximum rating |
| UL 94 V-0 molding compound | Prevents flame propagation in enclosed enclosures, satisfying safety compliance for industrial control panels |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220A | Same VWM/VBR/VC specs but in SMB (DO-214AA) surface-mount package; 600 W rating retained | Requires SMT reflow process; unsuitable for through-hole legacy designs or high-vibration mechanical retention | Select when board space is constrained and automated assembly is available |
| 1.5KE220A | Higher 1500 W peak power rating but larger DO-201AD package; identical VWM, VBR, VC values and unidirectional polarity | Better suited for higher-energy surge events (e.g., AC mains coupling) where 600 W is marginal | Choose when system-level surge testing exceeds IEC 61000-4-5 Level 4 requirements |
Compared with SMBJ220A and 1.5KE220A, P6KE220A-E3/73 offers optimal balance of proven DO-15 mechanical robustness, cost-effective through-hole assembly, and validated AEC-Q101 qualification - making it preferred for automotive aftermarket modules and industrial field-replaceable units where serviceability and vibration resistance are critical.

FAQ
What is the clamping voltage of P6KE220A-E3/73 and how is it measured?
The clamping voltage (VC) of P6KE220A-E3/73 is 328 V, measured at 1.8 A peak pulse current using a standardized 10/1000 µs double-exponential waveform. This value represents the maximum voltage imposed on the protected circuit during a surge event and is guaranteed per Vishay's datasheet test conditions at TA = 25 °C. The P6KE220A-E3/73 achieves this clamping performance due to its low incremental surge resistance and optimized silicon junction design.
Is P6KE220A-E3/73 suitable for automotive applications?
Yes, P6KE220A-E3/73 is AEC-Q101 qualified when ordered with the HE3 suffix (e.g., P6KE220AHE3/73). The E3 suffix version is commercial grade and RoHS compliant but not AEC-Q101 certified. For automotive use, confirm ordering code includes HE3 and verify qualification status via Vishay's official documentation. The P6KE220A-E3/73 itself meets all electrical and thermal specifications required for under-hood environments except formal stress-test validation.
What is the standoff voltage (VWM) of P6KE220A-E3/73 and why does it matter?
The standoff voltage (VWM) of P6KE220A-E3/73 is 185 V - the maximum continuous DC or RMS voltage the device blocks without entering avalanche conduction. This parameter ensures no leakage current flows during normal operation, preserving system efficiency and preventing false triggering. It must be selected ≥10–20 % above the system's maximum operating voltage; for a 150 V nominal bus, P6KE220A-E3/73 provides appropriate margin while maintaining effective clamping.
How does the DO-15 package of P6KE220A-E3/73 affect thermal performance?
The DO-15 package of P6KE220A-E3/73 delivers a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, enabling efficient heat transfer to PCB copper or external heatsinks via its axial leads. Unlike surface-mount packages, DO-15 allows direct mechanical attachment to metal chassis for enhanced conduction cooling. This makes P6KE220A-E3/73 especially effective in high-temperature environments where sustained power dissipation up to 5.0 W (at TL = 75 °C) is required.
Can P6KE220A-E3/73 replace bidirectional TVS diodes in circuit designs?
No, P6KE220A-E3/73 is unidirectional and cannot replace bidirectional TVS diodes such as P6KE220CA. Its cathode-marked polarity conducts only during positive transients relative to ground; negative excursions remain unprotected. Using P6KE220A-E3/73 in place of a bidirectional device leaves circuits vulnerable to reverse-polarity surges. Always match device polarity to system topology - P6KE220A-E3/73 is intended for DC rail protection with defined ground reference, not AC or floating signal lines.
