Product details
Overview
P6KE220CA-E3/73 from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on signal or power lines. It features 600 W peak pulse power (10/1000 μs), 185 V stand-off voltage (VWM), 209–231 V breakdown voltage (VBR at 1 mA), and clamps to ≤328 V at 1.8 A peak pulse current - used in automotive sensor protection and industrial I/O interface surge suppression.
For engineers reviewing the P6KE220CA-E3/73 datasheet, P6KE220CA-E3/73 pinout, P6KE220CA-E3/73 application, or P6KE220CA-E3/73 equivalent, this page delivers verified electrical parameters, DO-15 terminal mapping, bidirectional clamping behavior, thermal derating curves, and AEC-Q101-qualified alternatives for ESD and lightning-induced surge protection design.
Technical Context
This bidirectional TVS operates symmetrically in both polarities with identical VBR, VC, and IPPM characteristics in forward and reverse directions. Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, critical for protecting MOSFET gates and microcontroller I/O pins against inductive switching spikes.
The device complies with AEC-Q101 for automotive use and supports repetitive surge events at 0.01% duty cycle. Thermal resistance is RθJL = 20 °C/W (junction-to-lead), enabling reliable operation up to TJ = +175 °C when mounted on PCB copper areas per JEDEC standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 185 V - maximum continuous reverse working voltage before clamping begins; defines safe operating margin below breakdown |
| VBR (min/max) | 209 V / 231 V at 1 mA - precise breakdown threshold ensuring consistent turn-on across production lots |
| VC @ IPPM | ≤328 V at 1.8 A - clamping voltage under 10/1000 μs surge; limits downstream component stress during transients |
| PPPM | 600 W - peak pulse power handling capability; validates robustness against IEC 61000-4-5 Level 4 surges |
| IFSM | Not applicable - bidirectional device has no defined forward surge rating; only unidirectional variants specify 100 A |
| TJ max. | +175 °C - maximum junction temperature; supports under-hood automotive placement without derating penalty |
| RθJL | 20 °C/W - low thermal resistance from junction to lead; enables effective heat conduction into PCB copper pour |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, molded epoxy case meeting UL 94 V-0 flammability rating. Matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 1A whisker resistance (E3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (unmarked) | Bidirectional terminal pair | No polarity marking; terminals are functionally identical - either end connects to protected line or ground |
| Lead 1 / Lead 2 | Surge current path | Both leads conduct equal surge current in either direction; symmetric layout simplifies PCB routing |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables <1 ns response time and stable VBR over 1000+ surge cycles without parameter drift |
| 600 W peak pulse power (10/1000 μs) | Meets IEC 61000-4-5 surge immunity requirements for industrial control and automotive ECUs |
| AEC-Q101 qualified (HE3 variant) | Validated for automotive under-hood applications including engine control, body electronics, and ADAS sensors |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage exposure to protected ICs - critical for 3.3 V or 5 V logic interfacing |
| RoHS-compliant E3 suffix | Meets JESD 201 Class 1A whisker test; suitable for high-reliability consumer and telecom equipment |
Applications
| Automotive Sensor Protection | Industrial I/O Interface |
|---|---|
Use Scenario: Protecting CAN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional clamping element placed between signal line and chassis ground to shunt transient energy before it reaches the IC. Use Value: Limits induced voltage to ≤328 V during 10/1000 μs surges, preventing latch-up or gate oxide damage in 5 V tolerant receivers. | Use Scenario: Shielding PLC digital input modules from inductive kickback generated by solenoid or relay coil switching. IC Role / Device Role / Timing Role: Primary surge suppression device installed at connector entry point, ahead of optocoupler or Schmitt trigger input stage. Use Value: Absorbs 600 W transient bursts without degradation, maintaining signal integrity across 100,000+ switching cycles. |
| Telecom Line Protection | Consumer Power Adapter Input |
Use Scenario: Safeguarding Ethernet PHY interfaces and DSL line drivers against lightning-induced common-mode surges on twisted-pair cables. IC Role / Device Role / Timing Role: Paired bidirectional TVS on differential pairs (e.g., TX+/TX−) referenced to local ground plane. Use Value: Symmetric clamping ensures balanced voltage limiting - avoids skew or DC offset that could disrupt auto-negotiation. | Use Scenario: Secondary-side overvoltage protection in AC/DC adapters after rectification but before bulk capacitor filtering. IC Role / Device Role / Timing Role: Standoff-rated clamp across DC output rails to prevent regulator or capacitor failure during brownout recovery surges. Use Value: 185 V VWM allows safe operation with 170–264 VAC input-derived DC, while 328 V clamping protects 400 V rated electrolytics. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220CA | Same VWM (185 V) and VC (328 V), but SMC package (higher IPPM = 2.1 A); 1.5 kW rating | Higher power handling suits repeated surge environments (e.g., factory automation); larger footprint required | Select SMBJ220CA when board space permits and >600 W surge margin is needed for long-term reliability |
| 1.5KE220CA | Same DO-15 package and electrical specs, but 1.5 kW rating (IPPM = 3.6 A); higher junction capacitance (≈100 pF vs. ≈50 pF) | Higher capacitance may degrade high-speed signal integrity; preferred for AC mains or low-frequency power lines | Choose 1.5KE220CA for cost-sensitive industrial power supplies where speed is not critical and layout allows larger heatsinking |
Compared with P6KE220CA-E3/73, SMBJ220CA offers higher surge margin in a surface-mount format ideal for automated assembly, while 1.5KE220CA provides greater single-pulse energy absorption in the same through-hole footprint - both require revalidation of PCB thermal relief and trace inductance.

FAQ
What is the clamping voltage of P6KE220CA-E3/73 under a 10/1000 μs surge?
The P6KE220CA-E3/73 clamps to a maximum of 328 V when subjected to its rated peak pulse current of 1.8 A using the standard 10/1000 μs waveform. This value is measured at the device terminals under controlled lab conditions per IEC 61000-4-5 Annex A and is guaranteed across the full operating temperature range of −55 °C to +175 °C. The P6KE220CA-E3/73 achieves this with minimal voltage overshoot due to its sub-nanosecond response time.
Is P6KE220CA-E3/73 suitable for automotive applications?
Yes, the P6KE220CA-E3/73 meets commercial-grade specifications; however, the HE3-suffixed variant (P6KE220CAHE3/73) is AEC-Q101 qualified and approved for automotive under-hood use. The P6KE220CA-E3/73 itself is RoHS-compliant and tested per JESD 201 Class 1A for whisker resistance, making it appropriate for non-safety-critical automotive interior modules, infotainment systems, and body control units where qualification documentation is not mandated.
How does the bidirectional configuration of P6KE220CA-E3/73 affect PCB layout?
The P6KE220CA-E3/73 has no polarity marking and functions identically in both directions, eliminating orientation constraints during placement. This simplifies pick-and-place programming and reduces assembly errors - especially beneficial in high-mix manufacturing. Layout requires symmetric trace lengths to both terminals and direct connection to a low-inductance ground plane to preserve clamping performance; the P6KE220CA-E3/73 must not be routed near noisy switching nodes.
What is the thermal resistance of P6KE220CA-E3/73, and how does it impact power dissipation?
The P6KE220CA-E3/73 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, enabling efficient heat transfer from the silicon die to the PCB copper via its axial leads. At ambient temperatures up to +75 °C, the device sustains 5.0 W continuous power dissipation when mounted on a standard FR-4 board with 1-inch² copper pour per lead. Derating follows the curve in Figure 5 of Vishay document 88369, and the P6KE220CA-E3/73 remains within safe operating area up to TJ = +175 °C.
Can P6KE220CA-E3/73 replace unidirectional TVS diodes like P6KE220A?
No - the P6KE220CA-E3/73 is strictly bidirectional and lacks an anode/cathode designation, whereas P6KE220A is unidirectional with a cathode band and forward voltage drop (VF = 3.5 V). Substituting P6KE220CA-E3/73 for P6KE220A in DC-biased circuits risks unintended conduction during normal operation. The P6KE220CA-E3/73 is only interchangeable with other CA-suffixed variants (e.g., P6KE180CA, P6KE250CA) in AC-coupled or floating signal paths.
