Overview
1.5KE220C-E3/73 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode designed for high-energy surge protection in power and signal lines. It features a 209 V to 231 V breakdown voltage (VBR), 185 V maximum standoff voltage (VWM), 328 V clamping voltage (VC) at 4.6 A peak pulse current, 1500 W peak pulse power rating with 10/1000 µs waveform, and operates across -55 °C to +175 °C junction temperature range - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the 1.5KE220C-E3/73 datasheet, 1.5KE220C-E3/73 pinout, 1.5KE220C-E3/73 application, or 1.5KE220C-E3/73 equivalent, this page delivers verified electrical parameters, package dimensions, clamping behavior under transient stress, thermal resistance data, and direct alternatives validated for bidirectional TVS replacement in ESD- and lightning-susceptible circuits.
Technical Context
This device implements an avalanche-based silicon PN junction structure optimized for sub-nanosecond response (<1 ns) to fast-rising transients. Its bidirectional configuration enables symmetrical clamping in AC-coupled or floating signal paths without polarity constraints.
It sustains 1500 W peak pulse power per 10/1000 µs waveform at 25 °C, derating linearly above TA = 25 °C with RθJA = 75 °C/W and RθJL = 15.4 °C/W. The 0.108 %/°C temperature coefficient of VBR ensures stable breakdown across its full operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 209 V / 231 V - defines guaranteed conduction onset window under 1 mA test current; critical for margining against system overvoltage thresholds |
| VWM | 185 V - maximum continuous reverse working voltage before leakage exceeds 1 µA; sets upper limit for normal-mode operating voltage |
| VC @ IPPM | 328 V at 4.6 A - clamped voltage during 10/1000 µs surge; determines protected circuit's maximum transient exposure level |
| PPPM | 1500 W - peak pulse power handling capacity; supports IEC 61000-4-5 Level 4 (4 kV) surge immunity when properly mounted |
| IPPM | 4.6 A - peak pulse current corresponding to VC; used to size series impedance and verify PCB trace current capability |
| TJ Range | -55 °C to +175 °C - extended junction temperature range enables deployment in under-hood automotive and industrial control environments |
| RθJA | 75 °C/W - thermal resistance from junction to ambient; informs heatsinking requirements for repetitive surge duty cycles |

| Low incremental surge resistance | Minimizes VC overshoot during fast-rising edges (e.g., ESD, lightning-induced spikes), reducing stress on downstream ICs |
| AEC-Q101 qualified option available | HE3 suffix variants meet automotive-grade reliability testing - vibration, temperature cycling, HTRB - for engine control and ADAS modules |
Applications
| Automotive Sensor Interface Protection | Industrial PLC Analog Input Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor front-ends (e.g., pressure, temperature) from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional clamping element placed across differential signal pair or supply rail to shunt surge energy before it reaches precision amplifier or microcontroller input. Use Value: Maintains signal fidelity by limiting transient excursion to ≤328 V while surviving repeated 1500 W surges - enabling compliance with ISO 16750-2 Class IV. |
Use Scenario: Safeguarding 4–20 mA current loop inputs and ±10 V analog inputs in programmable logic controllers exposed to field wiring transients. IC Role / Device Role / Timing Role: Primary overvoltage clamp on input terminals, coordinated with series current-limiting resistor and optional gas discharge tube for multi-stage protection. Use Value: Clamps 1 kV/500 A surges to <330 V within 1 ns, preventing latch-up or gate oxide damage in op-amps and ADC drivers. |
| Telecom Line Interface Protection | Consumer Power Adapter Surge Suppression |
Use Scenario: Shielding Ethernet PHYs, DSL line drivers, and POTS interface ICs from induced lightning surges on outdoor copper lines per ITU-T K.20/K.21. IC Role / Device Role / Timing Role: First-line bidirectional TVS across line-to-line and line-to-ground, selected for symmetry and low capacitance to avoid signal distortion. Use Value: Delivers 1500 W surge handling with <0.5 pF junction capacitance (typ.) - preserving signal integrity up to 100 MHz without equalization. |
Use Scenario: Secondary-side overvoltage suppression in AC/DC adapters and USB PD chargers subjected to mains-borne surges and capacitor discharge events. IC Role / Device Role / Timing Role: Final-clamp device across DC output rails, activated only after primary MOV and fuse coordination fails. Use Value: Limits post-fuse surge voltage to ≤328 V with precise VBR tolerance (±5%), preventing catastrophic failure of downstream DC-DC converters and USB controllers. |
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 | DO-214AA package (smaller footprint), 200 W lower PPPM (1300 W), identical VBR range and VC (328 V) | Better suited for space-constrained PCBs; reduced surge margin requires verification against IEC 61000-4-5 Level 3 | Select SMBJ220CA when board area is constrained and surge repetition rate is low; confirm thermal performance with RθJA = 110 °C/W |
| 1.5SMC220CA | Surface-mount SMC package, same 1500 W rating, but higher VC (355 V) and wider VBR tolerance (±10%) | Higher clamping voltage increases risk of downstream component overstress in low-voltage systems (e.g., 3.3 V logic) | Prefer 1.5KE220C-E3/73 where clamping precision and low VC are critical; use 1.5SMC220CA only if SMT assembly is mandatory and system margin allows 27 V higher VC |
Compared with SMBJ220CA and 1.5SMC220CA, the 1.5KE220C-E3/73 offers superior thermal dissipation (RθJL = 15.4 °C/W), tighter VBR tolerance (±5%), and lower clamping voltage - making it optimal for high-reliability through-hole designs requiring repeatable surge immunity in harsh thermal environments.
