Product details
Overview
1.5KE220CA R0G from Taiwan Semiconductor is a bidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with nominal breakdown voltage 220 V, clamping voltage 344 V at 4.5 A peak pulse current, and working stand-off voltage 175 V. It protects automotive and industrial power rails against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the 1.5KE220CA R0G datasheet, 1.5KE220CA R0G pinout, 1.5KE220CA R0G application, or 1.5KE220CA R0G equivalent, this part delivers verified bidirectional surge suppression for 24 V and 48 V DC systems, meets AEC-Q101 qualification, and supports high-reliability ESD and inductive switching protection without polarity sensitivity.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with breakdown voltage range 198–242 V at 1 mA test current and maximum clamping voltage of 344 V under 10/1000 μs surge. Its low dynamic impedance and sub-5 ns response time ensure rapid voltage limiting during fast transients.
Rated for 1500 W peak pulse power at 25 °C and derated linearly above ambient temperature, it sustains junction temperatures from –55 °C to +175 °C and exhibits <1 μA leakage at 175 V, enabling stable operation in harsh thermal environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 198 V / 242 V - Ensures reliable conduction onset across manufacturing tolerance at 1 mA test current |
| VWM | 175 V - Maximum continuous DC or RMS operating voltage before significant leakage |
| VC @ IPP | 344 V at 4.5 A - Clamped voltage during full 10/1000 μs surge, defining protected circuit voltage ceiling |
| PPK | 1500 W - Peak transient power handling capability per JEDEC standard waveform |
| IPP | 4.5 A - Maximum non-repetitive peak impulse current supported at rated clamping voltage |
| TJ max | +175 °C - Enables use in under-hood automotive and industrial power supply environments |
| Package | DO-201 - Industry-standard axial leaded package with UL 94V-0 molding compound and tin-plated leads |
Pinout & Package

Applications
| Automotive Power Distribution | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting 24 V CAN bus power rail and sensor supply lines from load dump and alternator ripple. IC Role / Device Role / Timing Role: Bidirectional shunt clamp placed upstream of DC-DC converters and interface ICs to limit transient overvoltage.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ220CA | Same DO-214AC (SMA) package; lower PPK = 400 W; VC = 356 V @ 1.1 A | Not suitable for 1500 W ISO 7637-2 Pulse 1; limited to lower-energy ESD/EFT scenarios | Select only when board space constraints require surface-mount and surge energy is ≤400 W |
| ON Semiconductor 1.5SMC220CA | DO-214AB (SMC) package; identical 1500 W rating; VC = 344 V @ 4.5 A; same VBR range | Pin-compatible in footprint but requires rework for axial-to-SMD transition; higher thermal resistance than DO-201 | Use when SMD assembly is mandatory and thermal management allows for reduced derating |
Compared with 1.5KE220CA R0G, SMAJ220CA offers smaller size but insufficient surge capacity for automotive load dump, while 1.5SMC220CA matches power rating but trades axial lead robustness and lower thermal resistance for surface-mount compatibility.

FAQ
What does the 'CA' suffix indicate in 1.5KE220CA R0G?
The 'CA' suffix in 1.5KE220CA R0G denotes bidirectional configuration - meaning the device provides symmetrical transient suppression in both polarities, with identical breakdown and clamping characteristics regardless of voltage polarity applied. This eliminates polarity marking requirements and simplifies layout in AC-coupled or floating DC systems where reverse voltage transients are possible.
Is 1.5KE220CA R0G AEC-Q101 qualified?
Yes, 1.5KE220CA R0G is AEC-Q101 qualified. The 'R0G' ordering code includes AEC-Q101 stress testing per the 1.5KE series qualification report (Version O2104), covering HTGB, H3TRB, TC, and mechanical shock tests required for automotive under-hood and chassis applications.
What is the maximum clamping voltage of 1.5KE220CA R0G at its rated surge current?
The maximum clamping voltage of 1.5KE220CA R0G is 344 V at 4.5 A peak pulse current under the standard 10/1000 μs waveform. This value is guaranteed across temperature and process variation and defines the upper voltage limit imposed on protected circuits during full-rated transient events.
Can 1.5KE220CA R0G be used in place of a unidirectional TVS like 1.5KE220A?
No - 1.5KE220CA R0G is bidirectional and cannot replace unidirectional 1.5KE220A in circuits requiring polarity-specific clamping, such as DC power rails with defined ground reference and no reverse voltage risk. Substitution would eliminate forward-blocking capability and increase leakage in forward-biased conditions.
What is the working stand-off voltage (VWM) for 1.5KE220CA R0G?
The working stand-off voltage (VWM) for 1.5KE220CA R0G is 175 V. This is the maximum continuous DC or RMS voltage the device can withstand without exceeding 1 μA leakage current, making it suitable for 24 V and 48 V DC systems with safety margin against normal operating transients.
