Product details
Overview
1.5KE130A-T from Diodes Incorporated is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, designed for primary overvoltage protection of DC power rails and signal lines. It features a 111V reverse standoff voltage, 124–137V breakdown range at 1mA test current, 179V max clamping voltage at 8.4A peak pulse current, and operates from –55°C to +175°C - deployed in industrial power supplies and automotive ECUs.
For engineers reviewing the 1.5KE130A-T datasheet, 1.5KE130A-T pinout, 1.5KE130A-T application, or 1.5KE130A-T equivalent, key selection criteria include clamping voltage margin vs. protected IC VMAX, peak pulse current handling under IEC 61000-4-5 surge waveforms, thermal derating above +25°C, and axial lead compatibility with through-hole PCB layouts.
Technical Context
This unidirectional TVS diode uses a glass-passivated silicon junction to achieve fast response time (<1ps) and stable breakdown characteristics across temperature. Its DO-201 axial package supports high surge energy absorption while maintaining low leakage (<5μA at 111V) and predictable voltage temperature coefficient (+0.107%/°C).
The device operates as a shunt protector: under normal conditions it presents high impedance (>1GΩ), but avalanches into low-impedance conduction when transient voltage exceeds VRWM, clamping downstream circuitry to ≤179V during 1.0ms 8/20μs surges up to 1500W peak power.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500W at 1.0ms - sustains IEC 61000-4-5 Level 4 (4kV) surges without failure |
| Reverse Standoff Voltage | 111V - maximum continuous DC voltage before significant leakage begins |
| Breakdown Voltage Range | 124–137V @ 1mA - defines reliable avalanche initiation window for design margining |
| Max Clamping Voltage | 179V @ 8.4A - limits protected circuit voltage during worst-case transient event |
| Operating Temperature | –55°C to +175°C - enables use in under-hood automotive and industrial environments |
| Leakage Current | ≤5μA @ 111V - ensures minimal standby power loss in always-on systems |
| Tempco of VBR | +0.107%/°C - allows accurate clamping voltage prediction across full temperature range |
Pinout & Package
Package: DO-201 axial-leaded, transfer-molded epoxy (UL 94V-0), 1.12g weight, tin-plated leads solderable per MIL-STD-202 Method 208. Cathode band identifies polarity on unidirectional variant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lowest potential node; defines current return path during clamping |
| Cathode | High-side surge input terminal | Connected to protected line; avalanche conduction initiates here when VAK > VBR |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated die construction | Enables stable breakdown voltage and low leakage over 10+ years in humid environments |
| 1500W peak pulse rating | Supports single-event surge immunity up to 4kV IEC 61000-4-5 (8/20μs) |
| Fast response time | Sub-nanosecond turn-on protects sensitive logic from ESD and lightning-induced transients |
| RoHS-compliant & halogen-free | Meets IPC-1752A material declaration requirements for automotive and industrial OEMs |
| Axial DO-201 package | Enables manual rework, wave solder compatibility, and mechanical robustness in vibration-prone mounts |
Applications
| Industrial Power Supply Input Protection | Automotive Body Control Module (BCM) CAN Bus Line Protection |
|---|---|
Use Scenario: 24V DC input stage of programmable logic controller (PLC) power supply exposed to load dump and inductive switching transients. IC Role / Device Role / Timing Role: Shunt clamping device placed between +24V rail and chassis ground to limit voltage excursion during 12V/24V load dump events. Use Value: Clamps to ≤179V within nanoseconds, preventing damage to upstream rectifier diodes and downstream DC-DC controllers rated for 200V max input. |
Use Scenario: CAN_H and CAN_L lines in BCM subjected to ISO 7637-2 pulse 1, 2a, and 5a transients during vehicle cranking and alternator load dump. IC Role / Device Role / Timing Role: Unidirectional TVS on each CAN line referenced to ground, absorbing negative-going transients while preserving common-mode signaling integrity. Use Value: Maintains <5μA leakage at 111V standoff, avoiding CAN bus bias current errors; clamps 100A surge to <180V, protecting transceivers compliant with ISO 11898-2. |
| Telecom Remote Radio Unit (RRU) DC Feeder Protection | Renewable Energy Inverter DC Link Surge Suppression |
Use Scenario: –48V DC power feed to outdoor RRU mounted on cellular tower, subject to lightning-induced surges on long cable runs. IC Role / Device Role / Timing Role: Primary shunt protector on DC input, coordinated with upstream gas discharge tube (GDT) for staged protection. Use Value: Fast response captures initial surge edge before GDT fires; 1500W rating handles residual energy after GDT crowbar action. |
Use Scenario: 600–1000V DC link in solar string inverter exposed to induced surges from nearby lightning strikes. IC Role / Device Role / Timing Role: Secondary clamping device across DC bus capacitors, limiting overvoltage during fast-rising transients not fully suppressed by MOVs. Use Value: 179V clamping voltage provides 20% margin below typical 220V-rated film capacitor surge rating, extending capacitor lifetime under repeated stress. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A | Same 130V standoff, but 600W rating (SMB package), lower IPP = 4.7A, surface-mount only | Not suitable for high-energy 1500W surges; requires PCB space optimization over axial lead placement | Select when board space is constrained and surge threat level is ≤IEC 61000-4-5 Level 2 (1kV) |
| 1N6287 | Legacy 1500W DO-201 part with 130V standoff, but higher VC = 185V and wider VBR tolerance (±10%) | Less precise clamping margin; higher leakage (≤10μA) reduces suitability for low-power always-on nodes | Acceptable for cost-sensitive industrial designs where 6V higher clamping is tolerable |
Compared with SMBJ130A and 1N6287, the 1.5KE130A-T delivers tighter VBR tolerance (±5%), lower clamping voltage (179V vs. 185V), and verified 1500W surge capability in an industry-standard axial package - making it optimal for legacy-replacement and high-reliability surge-critical applications.

FAQ
Is the 1.5KE130A-T RoHS and halogen-free compliant?
Yes. The 1.5KE130A-T meets EU RoHS 2011/65/EU and RoHS 3 2015/863/EU directives, with lead-free finish and halogen/antimony content below 900ppm bromine, 900ppm chlorine, and 1000ppm antimony - certified as Diodes' "Green" product per internal specification DS21503 Rev. 12.
What is the maximum operating temperature and thermal derating behavior?
The device operates from –55°C to +175°C junction temperature. Peak pulse power derates linearly above +25°C ambient: at +75°C, PPk drops to ~1125W (75% of 1500W); full derating curves are provided in Figure 1 of DS21503, based on measured thermal resistance from junction to leads.
How does the 1.5KE130A-T differ from bidirectional 1.5KE130CA?
The 1.5KE130A-T is unidirectional with cathode band marking and specified for DC line protection; the 1.5KE130CA is bidirectional (no polarity marking), symmetric clamping for AC or differential signal lines, and exhibits identical VRWM, VBR, and VC values in both directions per datasheet Table 1.
Can this TVS diode be used in parallel for higher surge current handling?
No. Due to inherent VBR tolerance (±5%), paralleling multiple 1.5KE130A-T units causes current imbalance - one device will conduct first and absorb disproportionate energy, risking premature failure. For higher IPP, select a single higher-rated part like 3KP130A (3000W) or verify matched-bin devices with factory screening.
