Product details
Overview
1.5KE130A from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode with a nominal breakdown voltage of 130V, clamping voltage of 179V at 8.7A peak pulse current, and DO-201 package. It delivers fast response (<1.0ps), low dynamic impedance, and meets ISO 7637-2 Pulse 1/2a/2b/3a/3b for automotive load-dump and EFT immunity in power rail protection.
For engineers reviewing the 1.5KE130A datasheet, 1.5KE130A pinout, 1.5KE130A application, or 1.5KE130A equivalent, this part supports high-reliability DC power line surge suppression where precise VBR tolerance (124–137V), low leakage (<1µA @ 111V), and AEC-Q101 qualification are required.
Technical Context
The 1.5KE130A operates as a unidirectional avalanche diode, triggering when reverse voltage exceeds its 124–137V breakdown range at 1mA test current. Its 179V clamping voltage limits transient energy to protected downstream circuitry under 10/1000µs waveform stress.
It features a DO-201 axial package with cathode band marking, rated for -55°C to +175°C junction temperature, and exhibits 0.107%/°C VBR temperature coefficient - critical for stable clamping across automotive thermal environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR @ IT = 1mA | 124–137V - defines precise reverse conduction onset; ensures reliable triggering before system overvoltage damage |
| VWM | 111V - maximum continuous reverse working voltage; sets safe DC operating margin below breakdown |
| VC @ IPP = 8.7A | 179V - clamped voltage during 10/1000µs surge; determines peak stress on downstream ICs or regulators |
| PPK | 1500W - peak pulse power rating; enables robust handling of ISO 7637-2 Load Dump (Pulse 5a) transients |
| IPP | 8.7A - peak impulse current at VC; quantifies surge current capacity for transient energy absorption |
| ID @ VWM | <1µA - ultra-low blocking leakage; minimizes standby power loss and avoids false triggering in high-impedance circuits |
| TJ max | +175°C - extended junction temperature rating; supports under-hood automotive placement without derating |
Pinout & Package
Package: DO-201 axial leaded package with cathode band marking; 0.090g mass; UL 94V-0 molding compound; pure tin-plated leads compliant with J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to ground or low-side return path; conducts during forward surge (e.g., reverse battery protection) |
| Cathode | Reverse breakdown terminal | Connected to protected line (e.g., 12V rail); avalanches into conduction when VAK > VBR, shunting surge to ground |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per JESD22 standards |
| 1500W 10/1000µs surge capability | Withstands ISO 7637-2 Pulse 5a (load dump) up to 1500W without degradation or parametric shift |
| Clamping ratio VC/VBR ≈ 1.44 | Low ratio ensures minimal overvoltage overshoot during clamping - critical for protecting 130V-rated components |
| Dynamic impedance <15Ω (typ.) | Ensures rapid voltage stabilization during fast transients; reduces energy dissipation in upstream traces |
| 0.107%/°C VBR tempco | Stable breakdown threshold across -40°C to +125°C ambient - avoids premature triggering or failure to clamp |
Applications
| Automotive Power Rail Protection | Industrial DC Power Input |
|---|---|

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 | DO-214AC (SMA) package; 130V VBR min/max 124–137V; same 1500W rating but lower IPP (8.5A vs 8.7A); 179V VC | Surface-mount footprint; requires PCB rework; less suitable for through-hole legacy designs or high-vibration mounting | Select when automated SMT assembly is prioritized and thermal pad layout supports SMA package power dissipation. |
| ON Semiconductor 1.5SMC130A | DO-214AB (SMC) package; identical VBR (124–137V), VC (179V), and PPK (1500W); slightly higher leakage (≤5µA vs <1µA) | Higher profile SMC package; better thermal performance than DO-201 but larger board area; RoHS/halogen-free compliant | Choose for improved thermal management in high-power-density layouts where DO-201 lead spacing is insufficient. |
Compared with 1.5KE130A, SMAJ130A offers SMT compatibility at the cost of mechanical robustness and vibration resistance, while 1.5SMC130A provides superior thermal dissipation in space-constrained designs but increases board area and requires higher assembly precision.

FAQ
What is the exact breakdown voltage range for 1.5KE130A?
The 1.5KE130A has a guaranteed breakdown voltage range of 124V to 137V at 1mA test current (VBR min/max), as specified in the Electrical Specifications table on page 3 of the Taiwan Semiconductor datasheet. This narrow 10% tolerance ensures consistent clamping behavior across production lots and supports precise overvoltage margining in safety-critical designs.
Is 1.5KE130A unidirectional or bidirectional?
The 1.5KE130A is a unidirectional TVS diode, indicated by the absence of "CA" suffix and explicit listing under "Devices for Unidirectional Applications" in the datasheet. It conducts only in reverse bias above VBR and blocks forward current up to 3.5V - confirmed by VF = 3.5V @ 50A in Absolute Maximum Ratings.
Does 1.5KE130A meet AEC-Q101 requirements?
Yes, 1.5KE130A is explicitly AEC-Q101 qualified per the Features section and Ordering Information notes ("H" suffix denotes AEC-Q101 qualification). It undergoes stress testing including temperature cycling, highly accelerated life testing (HALT), and ESD per JESD22-A114, making it suitable for automotive powertrain and body electronics.
What is the clamping voltage of 1.5KE130A at its rated peak current?
The 1.5KE130A clamps to a maximum of 179V at 8.7A peak pulse current (IPP) under the standard 10/1000µs waveform. This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
Can 1.5KE130A be used in bidirectional configurations?
No - 1.5KE130A is strictly unidirectional. For bidirectional protection, Taiwan Semiconductor specifies the "1.5KE130CA" variant (not 1.5KE130A), which uses a back-to-back diode structure. Using 1.5KE130A in reverse polarity or AC applications risks permanent forward conduction and failure.
