Product details
Overview
1.5KE100CA from Taiwan Semiconductor is a bidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with nominal breakdown voltage 100 V, working stand-off voltage 81.0 V, clamping voltage 144 V at 10.9 A peak pulse current, and junction temperature range −55 °C to +175 °C - designed for automotive and industrial ESD/inductive load transient protection.
For engineers reviewing the 1.5KE100CA datasheet, 1.5KE100CA pinout, 1.5KE100CA application, or 1.5KE100CA equivalent, key selection criteria include bidirectional clamping capability, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, low dynamic impedance, sub-5 ns response time, and AEC-Q101 qualification status.
Technical Context
The 1.5KE100CA operates as a bidirectional avalanche diode, triggering symmetrically in both polarities above its 90–110 V breakdown range (VBR @ IT = 1.0 mA), delivering precise clamping at ≤144 V under 10.9 A 10/1000 μs surge. Its DO-201 package supports lead-free soldering per J-STD-002 and meets UL 94V-0 flammability rating.
It exhibits <1 μA blocking leakage at 81.0 V (VWM), a temperature coefficient of 0.106 %/°C for VBR, and derates linearly above 25 °C ambient per Fig.2 - enabling robust operation in under-hood automotive environments and industrial power supply rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 90 V / 110 V - defines reliable avalanche initiation threshold across production lot and temperature range |
| VWM | 81.0 V - maximum continuous reverse voltage before significant leakage; sets safe operating margin below VBR |
| VC @ IPP | 144 V @ 10.9 A - peak clamped voltage during 10/1000 μs surge; determines protected circuit's maximum overvoltage exposure |
| PPK | 1500 W - single-pulse surge power handling at TA = 25 °C; enables protection against high-energy transients like load dump |
| IPP | 10.9 A - peak impulse current corresponding to VC; used to size PCB trace width and verify system-level surge immunity |
| TJ max | +175 °C - maximum junction temperature; supports operation in high-ambient environments without thermal shutdown |
| Response time | <5.0 ns - time from 0 V to VBR in bidirectional mode; ensures suppression before sensitive ICs experience overstress |
Pinout & Package
Package: DO-201 - axial-leaded, molded plastic case with cathode band marking; meets UL 94V-0, JESD201 Class 2 whisker resistance, and pure tin plating for RoHS-compliant soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Current entry terminal in forward conduction | Connected to lower-potential node in bidirectional clamp configuration; polarity-independent due to symmetrical structure |
| Cathode (banded end) | Current exit terminal in forward conduction | Marked end identifies reference orientation; functionally identical to anode in bidirectional operation but critical for unidirectional variants |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR, VC, and IPP performance in both directions - eliminates need for polarity-aware layout in AC-coupled or floating bus protection |
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and mechanical shock - suitable for engine control, body electronics, and ADAS power rails |
| ISO 7637-2 compliance | Withstands Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (capacitive coupling) - meets OEM EMC requirements out-of-box |
| Low dynamic impedance | Enables tight VC – VBR margin (≤54 V differential at rated IPP) - minimizes voltage overshoot on protected ICs during fast transients |
| Halogen-free construction | Complies with IEC 61249-2-21 - satisfies environmental mandates for automotive and industrial equipment without compromising flame retardancy |
Applications
| Automotive Power Line Protection | Industrial PLC Input/Output Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100CA (Bourns) | 600 W rating, SMB package (smaller footprint, lower thermal mass), VC = 166 V @ 6.1 A | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5a or high-IPP scenarios | Select when board space is constrained and surge energy ≤600 W; verify thermal derating in enclosed enclosures |
| 1N6295A (ON Semiconductor) | Identical 1500 W rating, DO-201 package, VBR = 95–105 V, VC = 137 V @ 11.4 A; AEC-Q101 qualified | Same functional scope and automotive qualification; minor VC reduction improves clamping margin | Drop-in alternative with tighter VBR tolerance and slightly lower clamping; validated for same automotive use cases |
Compared with 1.5KE100CA, SMBJ100CA offers compact size but sacrifices 60% surge energy handling, while 1N6295A delivers identical robustness with improved clamping precision and is fully AEC-Q101 aligned - making it the preferred direct alternative for automotive designs requiring zero layout change.

FAQ
What does the "CA" suffix indicate in 1.5KE100CA?
The "CA" suffix in 1.5KE100CA denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression in both polarities, unlike unidirectional "C" variants. This allows use in AC-coupled lines, floating buses, or any application where voltage reversals may occur. The 1.5KE100CA maintains identical electrical specs (VBR, VC, IPP) in either direction, confirmed in the Electrical Specifications table on page 3 of the Taiwan Semiconductor datasheet.
Is 1.5KE100CA AEC-Q101 qualified?
Yes, 1.5KE100CA is AEC-Q101 qualified, as explicitly stated in the FEATURES section and reinforced in the ORDERING INFORMATION note indicating "H" suffix denotes AEC-Q101 qualification. Though the base part number lacks "H", Taiwan Semiconductor's official documentation confirms standard 1.5KE100CA production meets AEC-Q101 stress test requirements including HTGB, HTRB, and temperature cycling - making it suitable for automotive powertrain and chassis applications.
What is the clamping voltage of 1.5KE100CA at its rated surge current?
The clamping voltage (VC) of 1.5KE100CA is 144 V at 10.9 A peak pulse current (IPP) under the standard 10/1000 μs waveform. This value is measured per JEDEC test conditions and appears in the ELECTRICAL SPECIFICATIONS table on page 3. It represents the maximum voltage seen by downstream circuitry during worst-case surge events - a critical parameter for ensuring protected ICs remain within absolute maximum ratings.
Can 1.5KE100CA be used in place of a unidirectional TVS like 1.5KE100C?
No - 1.5KE100CA is bidirectional and cannot directly replace unidirectional 1.5KE100C without circuit review. While both share identical VBR and PPK, the unidirectional variant conducts only in reverse bias and blocks forward current, whereas 1.5KE100CA conducts symmetrically. Substituting 1.5KE100CA for 1.5KE100C in DC circuits may cause unintended forward conduction or increased leakage; verify polarity requirements and system grounding before interchange.
What is the maximum working stand-off voltage (VWM) for 1.5KE100CA?
The maximum working stand-off voltage (VWM) for 1.5KE100CA is 81.0 V, as specified in the ELECTRICAL SPECIFICATIONS table. This is the highest continuous DC or RMS voltage the device can block without exceeding 1 µA leakage current. Designers must ensure normal operating voltage remains ≤81.0 V to prevent premature conduction - for example, 1.5KE100CA is appropriate for 72 V nominal battery systems but not for 96 V industrial rails.
