Product details
Overview
1.5KE130A R0G from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with nominal breakdown voltage 130V, clamping voltage 179V at 8.7A peak pulse current, and working stand-off voltage 111V. It protects automotive and industrial power rails against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the 1.5KE130A R0G datasheet, 1.5KE130A R0G pinout, 1.5KE130A R0G application, or 1.5KE130A R0G equivalent, this page delivers verified electrical parameters, DO-201 terminal mapping, real-world protection use cases, and two validated alternative parts for surge immunity design.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: when transient voltage exceeds its 124–137V breakdown range (tested at 1mA), it avalanches to clamp the line at ≤179V while diverting up to 8.7A of 10/1000μs surge current. Its <1.0ps response time ensures sub-nanosecond turn-on from 0V to VBR.
Designed for high-reliability environments, it meets AEC-Q101 stress requirements and ISO 7637-2 immunity standards. Junction temperature rating extends to +175°C, and leakage current remains below 1μA at 111V - enabling stable operation in 12V/24V/48V automotive and industrial power systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR @ IT=1mA | 124–137V - defines precise avalanche onset threshold for reliable overvoltage triggering |
| VWM | 111V - maximum continuous DC or RMS operating voltage before leakage rises significantly |
| VC @ IPP=8.7A | 179V - clamped voltage during full 1500W surge, limiting downstream IC stress |
| PPK | 1500W - peak pulse power handling per 10/1000μs waveform, critical for load dump survival |
| IPP | 8.7A - maximum non-repetitive surge current the device safely clamps without failure |
| TJ max | +175°C - enables placement near hot components (e.g., power MOSFETs, DC/DC converters) |
| Leakage @ VWM | <1μA - negligible standby current draw, preserving battery life in always-on systems |
Pinout & Package
Package: DO-201 axial leaded package with cathode band marking; leads are pure tin plated, solderable per J-STD-002, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Ground reference node | Connected to system ground or low-side return path; completes clamping loop during transient |
| Cathode | Protected line input | Connected to rail under protection (e.g., 24V supply); avalanche occurs from cathode to anode |
Key Features
| Feature | Design Value |
|---|---|
| 1500W surge rating | Handles automotive load dump events (ISO 7637-2 Pulse 5a) without degradation |

Applications
| Automotive Power Rail Protection | Industrial DC Power Input |
|---|---|
Use Scenario: Protecting 24V CAN bus power lines against ISO 7637-2 Pulse 2b (inductive switch-off) and Pulse 5a (load dump). IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed between 24V rail and chassis ground to clamp surges before they reach CAN transceivers and microcontrollers. Use Value: Limits voltage to ≤179V during 8.7A transients, preventing latch-up or gate oxide damage in 3.3V/5V interface ICs. | Use Scenario: Safeguarding programmable logic controller (PLC) 24V DC input terminals from field-wiring induced transients and relay coil flyback. IC Role / Device Role / Timing Role: Primary front-end surge suppression element mounted directly at connector entry point, upstream of DC/DC converters and signal conditioning circuits. Use Value: Absorbs 1500W pulses without derating at +85°C ambient, maintaining protection integrity across extended industrial temperature ranges. |
| LED Driver Overvoltage Protection | Telecom Power Supply Clamp |
Use Scenario: Securing constant-current LED driver outputs against accidental AC mains coupling or lightning-induced surges on long cable runs. IC Role / Device Role / Timing Role: Unidirectional TVS connected across output terminals to clamp reverse polarity or overvoltage events before damaging LED strings or driver FETs. Use Value: 111V working voltage accommodates 100V-rated LED arrays while clamping at 179V - ensuring safe margin below driver IC breakdown limits. | Use Scenario: Adding secondary surge protection to -48V telecom rectifier outputs exposed to lightning-induced longitudinal surges on copper pairs. IC Role / Device Role / Timing Role: Back-to-back configuration (with another 1.5KE130A R0G) provides bidirectional clamping on -48V supply relative to return, meeting GR-1089-CORE requirements. Use Value: Dual-device arrangement achieves symmetrical ±179V clamping with matched VBR tolerance (124–137V), eliminating voltage imbalance in telecom power rails. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ130A | Same DO-214AC (SMA) package; 124–137V VBR, 179V VC @ 8.7A, but rated for 400W only | Lower power rating restricts use to non-load-dump scenarios (e.g., ESD-only zones) | Select when space-constrained PCB layout favors surface-mount and surge energy is limited to <400W |
| ON Semiconductor 1.5SMC130A | DO-214AB (SMC) package; identical 124–137V VBR, 179V VC, 1500W rating, but higher thermal resistance (junction-to-ambient) | Slightly reduced thermal performance in sealed enclosures without airflow | Prefer when existing SMC footprint is standardized and board-level thermal management is adequate |
Compared with 1.5KE130A R0G, SMAJ130A offers smaller size but sacrifices 73% surge energy capacity, while 1.5SMC130A matches power rating but requires more board area and careful thermal design - making 1.5KE130A R0G optimal for high-energy, through-hole-mounted automotive and industrial protection.

FAQ
What is the breakdown voltage range of the 1.5KE130A R0G?
The 1.5KE130A R0G has a guaranteed breakdown voltage range of 124V to 137V when tested at 1mA DC current. This specification ensures consistent avalanche initiation across production lots and temperature extremes, enabling predictable clamping behavior in 24V and 48V systems where overvoltage thresholds must be tightly controlled.
Does the 1.5KE130A R0G meet automotive qualification standards?
Yes, the 1.5KE130A R0G is AEC-Q101 qualified and explicitly designed for automotive applications. It passes stress tests including high-temperature reverse bias, temperature cycling, and humidity bias, and supports immunity to ISO 7637-2 transients (Pulse 1, 2a, 2b, 3a, 3b). The "R0G" suffix denotes RoHS-compliant, halogen-free construction per IEC 61249-2-21.
What is the clamping voltage of the 1.5KE130A R0G under surge conditions?
The 1.5KE130A R0G clamps to a maximum of 179V when subjected to its rated 8.7A peak pulse current (10/1000μs waveform). This value - measured per ANSI/IEEE C62.35 - defines the upper voltage limit imposed on protected circuitry during worst-case transients, ensuring compatibility with 200V-rated downstream components.
Can the 1.5KE130A R0G be used in bidirectional configurations?
No, the 1.5KE130A R0G is unidirectional only, with cathode band marking indicating polarity. For bidirectional protection, two 1.5KE130A R0G devices must be connected in series opposing configuration (anode-to-anode), or a dedicated bipolar part like 1.5KE130CA should be selected - which has symmetric breakdown in both directions.
What is the maximum junction temperature rating for the 1.5KE130A R0G?
The 1.5KE130A R0G has a maximum junction temperature (TJ) rating of +175°C, allowing operation in high-temperature environments such as engine compartments or enclosed industrial power supplies. This rating is maintained across its full power dissipation range and supports long-term reliability when mounted on appropriate copper land patterns per JEDEC standards.
