Product details
Overview
1.5KE100CA-T from Diodes Incorporated is a bidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, designed for overvoltage protection of DC power lines and signal interfaces. It features a 85.5V reverse standoff voltage, 95.0V minimum breakdown voltage at 1mA test current, 137V maximum clamping voltage at 11A peak pulse current, and operates across -55°C to +175°C.
For engineers reviewing the 1.5KE100CA-T datasheet, 1.5KE100CA-T pinout, 1.5KE100CA-T application, or 1.5KE100CA-T equivalent, this part delivers precise bidirectional surge suppression with verified clamping performance, RoHS-compliant lead-free finish, and axial-leaded DO-201 packaging suitable for high-reliability industrial and automotive board-level protection.
Technical Context
This TVS diode uses glass-passivated silicon junction technology to achieve fast response time (<1ps) and excellent clamping capability under 8/20μs surge waveforms. Its bidirectional configuration enables symmetrical protection against both positive and negative transients without polarity dependency.
The device is rated for 1500W non-repetitive peak pulse power at tP = 1.0ms, with steady-state power dissipation of 5.0W at 75°C lead temperature. Temperature coefficient of VBR is +0.106%/°C, ensuring stable breakdown behavior across its operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500W at 1.0ms pulse - sustains high-energy surges like IEC 61000-4-5 Level 4 (4kV) |
| Reverse Standoff Voltage (VRWM) | 85.5V - maximum continuous DC or RMS voltage before significant leakage |
| Breakdown Voltage (VBR) | 95.0V min @ 1mA - precise threshold where avalanche conduction begins |
| Clamping Voltage (VC) | 137V max @ 11A IPP - limits protected circuit voltage during surge event |
| Peak Pulse Current (IPP) | 11.0A - maximum transient current the device safely clamps without failure |
| Operating Temperature | -55°C to +175°C - supports under-hood automotive and industrial environments |
| Leakage Current (IR) | 5.0μA max @ 85.5V - ensures minimal standby power loss in always-on systems |
Pinout & Package
Package: DO-201 axial-leaded package with transfer-molded epoxy body (UL 94V-0), 1.12g weight, and tin-finished leads solderable per MIL-STD-202 Method 208. Bidirectional marking shows type number only (no cathode band).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Surge current entry (negative transient) | Conducts during negative excursions; symmetric with cathode for bidirectional operation |
| Cathode | Surge current entry (positive transient) | Conducts during positive excursions; identical electrical behavior to anode in CA variant |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated die construction | Enhances reliability and moisture resistance vs. epoxy-only passivation |
| Bidirectional surge suppression | Eliminates need for polarity-aware placement in AC-coupled or floating interfaces |
| RoHS-compliant lead-free finish | Meets EU Directive 2015/863/EU with <900ppm Br/Cl and <1000ppm Sb |
| Fast response time | Sub-nanosecond turn-on protects sensitive ICs before voltage overshoot damages inputs |
| High surge current handling | Withstands 200A forward surge (IFSM) for short-duration line faults or hot-swap events |
Applications
| Industrial Power Supply Protection | Automotive Body Control Module (BCM) |

FAQ
What is the difference between 1.5KE100A and 1.5KE100CA-T?
The "A" suffix denotes unidirectional operation with cathode marking, while "CA" indicates bidirectional symmetry-no polarity marking required. Both share identical 85.5V standoff and 137V clamping, but 1.5KE100CA-T protects against transients of either polarity without orientation constraints, simplifying layout and reducing BOM count in AC-coupled or floating circuits.
Can 1.5KE100CA-T replace P6KE100CA in a design?
No-1.5KE100CA-T is rated for 1500W peak pulse power, whereas P6KE100CA is rated for 600W. Substituting would risk thermal runaway under IEC 61000-4-5 Level 4 surges. The 1.5KE series also uses DO-201 packaging versus DO-15 for P6KE, requiring PCB footprint revision and requalification of mechanical stress margins.
Is 1.5KE100CA-T qualified to AEC-Q101?
No-this specific part is not AEC-Q101 qualified. Diodes offers AEC-Q101 versions under the "Automotive Grade" designation (e.g., 1.5KE100CAQ-T), which undergo additional stress testing and are manufactured in IATF 16949-certified facilities. Standard 1.5KE100CA-T is intended for industrial and commercial applications.
What is the maximum allowable mounting torque for DO-201 leads?
DO-201 axial leads are specified for manual or automated insertion with no defined torque limit; however, mechanical stress must be limited to avoid die fracture. Diodes recommends ≤0.25 N·m bending moment at lead exit point and prohibits twisting or kinking during board assembly. Lead forming should occur ≥3mm from package body using rounded tools.
