Product details
Overview
1.5KE130CA-T from Diodes Incorporated is a bidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, designed for overvoltage protection of DC power rails and signal lines. It features a 111V reverse standoff voltage, 124–137V breakdown range at 1mA, 179V max clamping voltage at 8.4A peak pulse current, and operates from –55°C to +175°C. Used in industrial power supplies and automotive ECUs to absorb ESD and lightning-induced surges.
For engineers reviewing the 1.5KE130CA-T datasheet, 1.5KE130CA-T pinout, 1.5KE130CA-T application, or 1.5KE130CA-T equivalent, key selection criteria include clamping voltage margin vs. protected IC VMAX, unidirectional/bidirectional polarity match, thermal derating at elevated ambient, and DO-201 axial lead mechanical compatibility with through-hole PCB layouts.
Technical Context
This bidirectional TVS diode uses glass-passivated silicon junctions to achieve fast response (<1ps) and stable clamping under 8.3ms surge waveforms. Its symmetrical I-V curve enables protection against both positive and negative transients without external polarity management.
The device sustains 1500W peak pulse power (tP = 1.0ms) with 0.107%/°C voltage temperature coefficient and 5.0μA max reverse leakage at 111V, ensuring low standby power loss and predictable trip behavior across automotive and industrial temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500W at 1.0ms - absorbs high-energy surges like ISO 7637-2 Pulse 5a without failure |
| Reverse Standoff Voltage | 111V - maximum continuous DC voltage before significant leakage begins |
| Breakdown Voltage Range | 124–137V @ 1mA - defines guaranteed conduction onset under transient stress |
| Max Clamping Voltage | 179V @ 8.4A - limits voltage seen by downstream circuitry during worst-case surge |
| Operating Temperature | –55°C to +175°C - supports under-hood automotive and industrial environments |
| Leakage Current | ≤5.0μA @ 111V - ensures minimal power drain on protected 110V DC bus |
Pinout & Package
Package: DO-201 axial-leaded through-hole package with transfer-molded epoxy body (UL 94V-0), 1.12g mass, and tin-finished leads solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during negative transients | One end of symmetrical junction; no cathode marking on bidirectional variant |
| Cathode | Current entry point during positive transients | Other end of symmetrical junction; device functions identically in either orientation |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated die construction | Enables stable leakage and breakdown performance across humidity and thermal cycling |
| Bidirectional configuration | Protects AC-coupled or floating signal lines without polarity-sensitive layout constraints |
| 1500W peak pulse rating | Meets IEC 61000-4-5 Level 4 (4kV line-to-line) surge immunity requirements |
| RoHS-compliant, halogen-free "Green" finish | Complies with EU Directive 2015/863/EU and automotive PPAP material declarations |
Applications
| Industrial Power Supply Protection | Automotive Body Control Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130CA | 600W rating, SMB surface-mount package, 179V clamping at 3.3A | Lower power handling; suited for space-constrained PCBs with lower surge exposure | Select when board area is limited and peak surge energy does not exceed 600W |
| 1.5SMC130CA | 1500W rating, SMC surface-mount package, 179V clamping at 8.4A, same electrical specs | Same protection level but requires rework for SMT assembly and thermal pad design | Choose for automated assembly and improved thermal dissipation via copper pour |
Compared with 1.5KE130CA-T, SMBJ130CA offers smaller footprint but reduced surge capacity, while 1.5SMC130CA delivers identical clamping and power rating in a surface-mount format-enabling higher-density layouts and better thermal coupling to PCB planes.

FAQ
What is the difference between 1.5KE130CA-T and 1.5KE130A-T?
The "C" suffix denotes bidirectional configuration: 1.5KE130CA-T clamps both positive and negative transients symmetrically, while 1.5KE130A-T is unidirectional and requires correct anode/cathode orientation. Bidirectional operation eliminates polarity-dependent layout errors and simplifies protection of AC or floating nodes.
Can 1.5KE130CA-T be used in parallel for higher surge current handling?
Yes, but only with matched devices and balanced PCB trace inductance. The 0.107%/°C VBR tempco ensures reasonable current sharing across temperature, though derating to 80% of total rated current is recommended to avoid thermal runaway due to minor parameter spread.
Is 1.5KE130CA-T compliant with AEC-Q200 for automotive use?
No-this part is not AEC-Q200 qualified. Diodes Incorporated offers AEC-Q200 versions under the P4SMA and SMAJ families; for automotive applications requiring PPAP or IATF 16949 traceability, contact Diodes' automotive sales team for qualified alternatives.
What is the significance of the "-T" suffix in the part number?
The "-T" indicates tape-and-reel packaging: 1,000 pieces per 13-inch reel. This format supports automated pick-and-place assembly and ensures consistent lead coplanarity and moisture sensitivity level (MSL) 1 compliance per J-STD-020 for immediate placement without baking.
