Product details
Overview
P6KE220-E3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary 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 (10/1000 µs), and operates across –55 °C to +175 °C junction temperature range - deployed in automotive engine control units, industrial PLC I/O modules, and telecom power supply inputs.
For engineers reviewing the P6KE220-E3/73 datasheet, P6KE220-E3/73 pinout, P6KE220-E3/73 application, or P6KE220-E3/73 equivalent, key selection criteria include verified clamping performance under 10/1000 µs surge, unidirectional polarity marking (cathode band), DO-204AC (DO-15) package compatibility with through-hole PCB layouts, and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
This TVS diode employs a glass-passivated silicon junction optimized for fast response (<1 ns) to transient events such as ESD, inductive switching spikes, and lightning-induced surges. Its low incremental surge resistance and stable clamping behavior ensure predictable voltage limiting during repetitive 0.01% duty cycle pulses.
The device operates in avalanche mode above VBR, delivering precise clamping at VC = 328 V when subjected to IPPM = 1.8 A (10/1000 µs). Thermal resistance is characterized at RθJL = 20 °C/W (junction-to-lead), supporting reliable power dissipation up to 5.0 W on an infinite heatsink at TL = 75 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 185 V maximum - ensures no conduction during normal 170–180 V DC rail operation |
| VBR (min/max) | 209 V / 231 V at 1.0 mA - defines guaranteed avalanche initiation threshold |
| VC @ IPPM | 328 V at 1.8 A (10/1000 µs) - maximum protected-circuit voltage during worst-case surge |
| PPPM | 600 W - sustains single high-energy transients without degradation |
| IFSM | 100 A (8.3 ms half-sine) - withstands non-repetitive inrush or fault currents |
| TJ range | –55 °C to +175 °C - supports under-hood automotive and industrial ambient extremes |
| Leakage @ VWM | 1.0 µA max - negligible standby power loss in always-on systems |
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 solderability standards. Cathode identified by color band on body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or return path; completes clamping loop during transient |
| Cathode | High-side connection point | Marked with band; connects to protected line - conducts avalanche current to ground |

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 SMC (DO-214AB) surface-mount package; 600 W rating retained | Requires rework of PCB layout for SMD assembly; better suited for high-density boards | Select SMBJ220A only if space-constrained designs mandate SMD footprint and thermal pad access is available |
| 1.5KE220A | Higher 1500 W peak power rating; same DO-204AC package; VC = 306 V @ 4.9 A (10/1000 µs) | Over-spec'd for typical 600 W requirements; higher cost and larger physical size than needed | Choose 1.5KE220A only when legacy designs require backward compatibility or surge margin exceeds 600 W |
Compared with SMBJ220A and 1.5KE220A, P6KE220-E3/73 delivers optimal cost-performance balance for through-hole automotive and industrial protection - matching required clamping voltage while minimizing board area and procurement complexity.

FAQ
What is the polarity configuration of the P6KE220-E3/73?
The P6KE220-E3/73 is a unidirectional TVS diode, with cathode indicated by a visible color band on the DO-204AC body. It conducts only when the cathode is biased positively relative to the anode - making it suitable for DC rail protection where reverse voltage is not expected. This differs from bi-directional variants (e.g., P6KE220CA) that suppress both polarities.
Does the P6KE220-E3/73 meet AEC-Q101 qualification?
Yes, the P6KE220-E3/73 carries the "E3" suffix indicating RoHS compliance and AEC-Q101 qualification per Vishay's documentation (Document Number 88369, Revision 18-Sep-12). This certification validates its suitability for automotive applications including powertrain and chassis control modules where reliability under thermal and mechanical stress is critical.
What is the maximum clamping voltage of the P6KE220-E3/73 under standard test conditions?
The P6KE220-E3/73 has a maximum clamping voltage (VC) of 328 V when subjected to a 10/1000 µs waveform at IPPM = 1.8 A. This value is measured at TA = 25 °C and defines the upper voltage limit imposed on protected circuitry during a standardized surge event - essential for ensuring downstream components remain within safe operating voltage ranges.
Can the P6KE220-E3/73 be used in AC line protection applications?
No - the P6KE220-E3/73 is a unidirectional TVS diode rated for DC standoff (VWM = 185 V), and is not designed for continuous AC voltage reversal. For AC line protection, bi-directional variants like P6KE220CA or purpose-built AC-rated MOVs/TVS arrays are required to handle both half-cycles without forward conduction during normal operation.
What is the thermal resistance specification for the P6KE220-E3/73?
The P6KE220-E3/73 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, measured under standard test conditions. This parameter enables accurate estimation of junction temperature rise during pulse events and informs heatsinking decisions - especially important in high-ambient or high-duty-cycle applications where sustained power dissipation approaches the 5.0 W rating.
