Product details
Overview
P6KE220C-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 209 V minimum breakdown voltage (VBR), 185 V maximum stand-off voltage (VWM), 328 A peak pulse current (IPPM) under 10/1000 μs waveform, and 600 W peak pulse power dissipation - deployed in automotive sensor protection and industrial I/O interface circuits.
For engineers reviewing the P6KE220C-E3/73 datasheet, P6KE220C-E3/73 pinout, P6KE220C-E3/73 application, or P6KE220C-E3/73 equivalent, key selection criteria include clamping voltage (VC = 328 V at IPPM), bi-directional polarity, DO-204AC (DO-15) package compatibility, and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
This device operates as a voltage-clamping protector with symmetrical bi-directional conduction - no cathode marking, enabling use on AC-coupled or floating signal paths. Its glass-passivated junction delivers fast response time (<1 ns) and low incremental surge resistance, critical for suppressing ESD and inductive switching spikes before downstream IC damage occurs.
Thermal performance is defined by RθJL = 20 °C/W (junction-to-lead) and RθJA = 75 °C/W (junction-to-ambient), supporting operation up to TJ = 175 °C. The 10/1000 μs waveform rating reflects standardized surge immunity testing per ANSI/IEEE C62.35, with derating applied above 25 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 209 V / 231 V at IT = 1.0 mA - defines reliable turn-on threshold across production lot and temperature |
| VWM | 185 V - maximum continuous reverse voltage before leakage exceeds 1.0 μA, sets operating margin below clamping |
| VC @ IPPM | 328 V at 328 A (10/1000 μs) - actual worst-case voltage seen by protected circuit during surge |
| PPPM | 600 W - peak transient energy handling capacity without failure, validated per JEDEC JESD22-A114 |
| IPPM | 328 A - maximum non-repetitive surge current the device safely clamps, determines PCB trace sizing |
| TJ max. | 175 °C - maximum junction temperature enabling high-temperature automotive under-hood deployment |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with UL 94 V-0 molded epoxy housing |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, cylindrical epoxy body, matte tin-plated leads solderable per J-STD-002. Bi-directional construction means no polarity marking; both terminals are electrically symmetric.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both terminals conduct identically in either direction - enables placement on unidirectional or bidirectional lines without orientation check |
| Lead 1 / Lead 2 | Thermal and mechanical interface | Leads serve as primary heat path to PCB copper; RθJL = 20 °C/W requires ≥ 10 mm² copper pour per lead for full power rating |
Key Features
| Feature | Design Value |
|---|---|
| Bi-directional clamping | Enables single-device protection of AC signals, differential buses (e.g., RS-485), or floating sensor outputs without polarity concerns |
| 600 W peak pulse power | Withstands IEC 61000-4-5 Level 4 surges (4 kV line-earth, 2 kV line-line) when properly mounted on ≥ 1 oz copper |
| AEC-Q101 qualified | Validated for automotive applications including engine control modules, body electronics, and ADAS sensor interfaces |
| Glass passivated junction | Ensures stable VBR over lifetime and humidity exposure - critical for industrial field-deployed equipment |
| Low clamping ratio (VC/VBR ≈ 1.57) | Minimizes overvoltage stress on protected MOSFETs or microcontrollers during transient events |
Applications
| Automotive Sensor Protection | Industrial I/O Interface |
|---|---|
Use Scenario: Protecting ABS wheel speed sensor signal lines from load dump and inductive kickback in 12 V vehicle systems. IC Role / Device Role / Timing Role: Voltage clamping element placed between signal line and ground, responding within <1 ns to transients exceeding 185 V.

Use Scenario: Shielding PLC analog input channels (4–20 mA, 0–10 V) from field wiring-induced lightning surges. IC Role / Device Role / Timing Role: Primary overvoltage clamp on terminal block inputs, operating in bi-directional mode to handle polarity-reversal faults. Use Value: Maintains system uptime by absorbing 600 W surges without degradation, eliminating need for redundant protection stages. |
| Consumer Power Adapter Input | Telecom Line Card Surge Protection |
Use Scenario: Secondary-side transient suppression on DC output rails of wall adapters subject to capacitive discharge events. IC Role / Device Role / Timing Role: Fast-acting shunt device that diverts surge current away from LDO regulators and USB port controllers.

Use Scenario: Front-end protection for Ethernet PHY interfaces exposed to induced surges via long cable runs in building infrastructure. IC Role / Device Role / Timing Role: First-line bi-directional clamp on differential pairs (e.g., MDI-X), coordinated with common-mode chokes. Use Value: Meets GR-1089-CORE Level 3 (10/700 μs, 1 kV) requirements while maintaining <1.5 pF junction capacitance at 0 V bias. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220CA-T | DO-214AA (SMB) package, 3.5 mm × 3.5 mm footprint, 300 W PPPM, VC = 356 V @ 243 A | Surface-mount only; unsuitable for through-hole legacy designs or high-vibration mechanical retention | Select when board space is constrained and reflow assembly is available; verify thermal pad layout matches RθJA = 40 °C/W spec |
| 1.5KE220CA | DO-201AD package, same 600 W rating, VC = 328 V @ 328 A, but 1.5 g unit weight vs. 0.432 g for P6KE220C-E3/73 | Larger mechanical footprint and higher thermal mass - better for infrequent high-energy surges, less responsive to fast ESD | Prefer for telecom central office equipment where surge repetition is rare and mechanical robustness outweighs response speed |
Compared with SMBJ220CA-T and 1.5KE220CA, P6KE220C-E3/73 offers optimal balance of axial-lead mechanical reliability, AEC-Q101 qualification, and 600 W capability in the smallest DO-204AC form factor - making it preferred for cost-sensitive automotive and industrial through-hole designs requiring proven field longevity.

FAQ
What is the polarity configuration of P6KE220C-E3/73?
P6KE220C-E3/73 is a bi-directional TVS diode with symmetrical terminal characteristics - neither end is marked as anode or cathode. This allows installation in either orientation on AC-coupled or floating signal paths, simplifying layout and eliminating polarity verification during assembly. The "C" suffix explicitly denotes bi-directional functionality per Vishay's naming convention.
Does P6KE220C-E3/73 meet automotive qualification standards?
Yes, P6KE220C-E3/73 is AEC-Q101 qualified, as confirmed in the Vishay datasheet revision 18-Sep-12 (Document Number: 88369). This qualification validates its suitability for automotive applications including engine control units, body electronics, and ADAS sensor interfaces - covering stress tests for temperature cycling, humidity, mechanical shock, and surge endurance.
What is the maximum clamping voltage of P6KE220C-E3/73 under surge conditions?
The maximum clamping voltage (VC) of P6KE220C-E3/73 is 328 V, measured at its rated peak pulse current of 328 A using the standardized 10/1000 μs waveform. This value represents the highest voltage the protected circuit will experience during a worst-case transient event, directly informing downstream component voltage ratings and safety margins.
How does the DO-204AC package of P6KE220C-E3/73 affect thermal performance?
The DO-204AC (DO-15) package of P6KE220C-E3/73 provides RθJL = 20 °C/W (junction-to-lead) and RθJA = 75 °C/W (junction-to-ambient). To sustain full 600 W pulse rating, each lead must connect to ≥10 mm² of 1 oz copper; insufficient copper area increases junction temperature and reduces surge survivability. Lead length beyond 9.5 mm degrades thermal performance per Fig. 5.
Is P6KE220C-E3/73 RoHS compliant and halogen-free?
Yes, P6KE220C-E3/73 carries the "E3" suffix, indicating RoHS compliance per Directive 2011/65/EU and halogen-free status per JEDEC JS709A. The matte tin-plated leads meet J-STD-002 solderability requirements, and the UL 94 V-0 epoxy molding compound ensures flame-retardant housing - verified in Vishay's material categorization documentation (doc?99912).
