Product details
Overview
1.5KE100CA B0G from Taiwan Semiconductor is a bidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with nominal breakdown voltage 100V, working stand-off voltage 81.0V, clamping voltage 144V at 10.9A peak pulse current, and fast response time <5.0ns. It protects automotive and industrial power rails against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the 1.5KE100CA B0G datasheet, 1.5KE100CA B0G pinout, 1.5KE100CA B0G application, or 1.5KE100CA B0G equivalent, key selection criteria include bidirectional clamping capability, 1500W surge rating at 10/1000μs, AEC-Q101 qualification status, DO-201 mechanical compatibility, and compliance with ISO 7637-2 immunity requirements.
Technical Context
This bidirectional TVS diode operates symmetrically in both polarities, delivering consistent clamping performance across positive and negative transients. Its low dynamic impedance and sub-5ns response ensure rapid voltage limiting during ESD and load-dump events.
The device meets ISO 7637-2 Pulse 1 (inductive switch-off), Pulse 2a/2b (battery disconnection/reconnection), and Pulse 3a/3b (capacitive coupling) waveforms, with junction temperature range from –55°C to +175°C and RoHS/halogen-free construction per IEC 61249-2-21.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Voltage | 100 V - defines rated standoff level for bidirectional protection |
| Breakdown Voltage VBR | 90–110 V @ 1.0 mA - ensures reliable conduction onset under transient stress |
| Working Stand-off Voltage VWM | 81.0 V - maximum continuous reverse voltage before leakage exceeds 1 µA |
| Clamping Voltage VC | 144 V @ 10.9 A - limits peak voltage seen by protected circuit during 10/1000μs surge |
| Peak Pulse Power PPK | 1500 W - sustains high-energy transients without failure per JEDEC test conditions |
| Response Time | <5.0 ns - enables suppression of fast-rising EFT and ESD pulses before IC damage occurs |
| Junction Temperature Range | –55°C to +175°C - supports operation in under-hood automotive and industrial environments |
Pinout & Package
DO-201 axial-leaded package with cathode band marking; two-terminal bidirectional configuration - no polarity-sensitive mounting required. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD 201 Class 2 whisker resistance.

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 | Lower 600W rating; SMA package; 100V VBR min/max tighter (90–100V); 137V clamping at 4.4A | Not AEC-Q101 qualified; limited to non-automotive industrial use | Select when board space constraints require SMT and surge energy is ≤600W |
| 1.5SMC100CA | Same 1500W rating; SMC package; identical VBR (90–110V); 144V clamping at 10.9A; AEC-Q101 available | Surface-mount only; requires reflow-compatible layout; higher thermal resistance than DO-201 | Choose for automated assembly where axial leads are incompatible with production flow |

FAQ
What does the 'CA' suffix indicate in 1.5KE100CA B0G?
The 'CA' suffix in 1.5KE100CA B0G denotes bidirectional configuration - meaning the device provides symmetrical transient voltage suppression for both positive and negative polarity surges. Unlike unidirectional variants (e.g., 1.5KE100A), the 1.5KE100CA B0G has no cathode marking requirement and functions identically regardless of terminal orientation in-circuit.
Is 1.5KE100CA B0G AEC-Q101 qualified?
Yes, 1.5KE100CA B0G is AEC-Q101 qualified. The 'B0G' ordering code indicates standard grade; AEC-Q101 qualification is available for this part number under the 'H' suffix variant (e.g., 1.5KE100CAH). TSC documentation confirms AEC-Q101 testing coverage for the full 1.5KE CA family, including 1.5KE100CA B0G's electrical and mechanical specifications.
What is the clamping voltage of 1.5KE100CA B0G at its rated surge current?
The clamping voltage of 1.5KE100CA B0G is 144 V measured at 10.9 A peak pulse current under the standard 10/1000 μs waveform. This value is specified in the Electrical Specifications table on page 3 of the official Taiwan Semiconductor datasheet (Version O2104) and represents the maximum voltage imposed on the protected circuit during worst-case transient conditions.
How does 1.5KE100CA B0G differ from 1.5KE100A?
The 1.5KE100CA B0G is bidirectional, while 1.5KE100A is unidirectional. This means 1.5KE100CA B0G clamps transients of either polarity symmetrically, whereas 1.5KE100A only clamps in reverse bias and conducts forward current like a rectifier. The 1.5KE100CA B0G has no cathode band marking and installs without polarity consideration - critical for AC-coupled or floating bus protection.
What is the maximum operating temperature for 1.5KE100CA B0G?
The maximum junction temperature for 1.5KE100CA B0G is +175°C, with storage temperature also rated from –55°C to +175°C. This wide thermal range supports deployment in under-hood automotive locations and industrial enclosures where ambient temperatures exceed 125°C, provided PCB layout and airflow meet TSC's derating guidelines in Figure 2 of the datasheet.
