Product details
Overview
1.5KE250CA R0G from Taiwan Semiconductor is a bidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with nominal breakdown voltage 250V, clamping voltage 360V at 4.3A peak pulse current, and working stand-off voltage 202V. It protects automotive power electronics, industrial control inputs, and DC bus lines against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the 1.5KE250CA R0G datasheet, 1.5KE250CA R0G pinout, 1.5KE250CA R0G application, or 1.5KE250CA R0G equivalent, key selection criteria include bidirectional clamping performance, 175°C junction temperature rating, AEC-Q101 qualification status, and compliance with automotive EFT immunity standards.
Technical Context
This bidirectional TVS diode operates symmetrically in both polarities, delivering consistent clamping behavior across positive and negative transients. Its low dynamic impedance and sub-5ns response time ensure rapid suppression of fast-rising EFT and load-dump events.
The device meets ISO 7637-2 for automotive electrical disturbances and supports steady-state power dissipation up to 5W at 75°C lead temperature. Its DO-201 package enables high surge robustness while maintaining compatibility with standard through-hole assembly processes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ250CA | DO-214AA package, 600W rating, lower clamping voltage (356V), higher IPP (5.6A) | Surface-mount alternative with reduced surge capacity but smaller footprint | Select when board space is constrained and 600W surge margin suffices |
| 1.5SMC250CA | DO-214AB package, 1500W rating, identical VBR/VC, slightly higher leakage (5µA @ VWM) | Same power rating but SMC package offers improved thermal mass vs. DO-201 | Select when enhanced thermal performance under repeated surges is critical |
Compared with 1.5KE250CA R0G, SMBJ250CA trades surge robustness for compactness, while 1.5SMC250CA matches power handling but improves thermal stability-both require layout changes due to different footprints and mounting methods.

FAQ
What does the 'CA' suffix indicate in 1.5KE250CA R0G?
The 'CA' suffix in 1.5KE250CA R0G denotes a bidirectional configuration-meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. This distinguishes it from unidirectional variants (e.g., 1.5KE250A), which require correct polarity orientation. The 1.5KE250CA R0G is functionally identical to 1.5KE250C but includes RoHS-compliant plating and green compound per TSC's O2104 revision.
Is 1.5KE250CA R0G AEC-Q101 qualified?
Yes, 1.5KE250CA R0G is AEC-Q101 qualified, as confirmed by Taiwan Semiconductor's documentation for the 1.5KE series with 'H' or 'R0G' suffixes indicating automotive-grade screening. The qualification covers temperature cycling, high-temperature reverse bias (HTRB), and ESD testing per the AEC-Q101 stress test plan, making 1.5KE250CA R0G suitable for engine control units, body electronics, and ADAS power domains.
What is the maximum clamping voltage of 1.5KE250CA R0G under surge conditions?
The maximum clamping voltage (VC) of 1.5KE250CA R0G is 360V at a peak pulse current (IPP) of 4.3A, measured using the standard 10/1000µs double-exponential waveform. This value ensures downstream components see limited overvoltage stress during transient events, and is guaranteed across the full operating temperature range of –55°C to +175°C per the official 1.5KE250CA R0G datasheet.
How does the DO-201 package of 1.5KE250CA R0G affect thermal performance?
The DO-201 package of 1.5KE250CA R0G supports 5W steady-state power dissipation at a lead temperature (TL) of 75°C when mounted on a 0.6" × 0.6" copper pad. Its axial-leaded construction allows direct heat conduction into PCB copper, but requires adequate trace width and thermal relief design. Derating follows Fig.2 in the 1.5KE250CA R0G datasheet, reducing peak power linearly above 25°C ambient.
Does 1.5KE250CA R0G meet ISO 7637-2 Pulse 1 and Pulse 2b requirements?
Yes, 1.5KE250CA R0G explicitly meets ISO 7637-2 for Pulse 1 (inductive load dump), Pulse 2a/2b (battery disconnection), and Pulse 3a/3b (electrical fast transients), as stated in the "FEATURES" section of the official datasheet. Its 1500W surge capability and 360V clamping voltage provide sufficient margin to suppress these standardized automotive transients without degradation, provided layout minimizes parasitic inductance in the protection path.
