Product details
Overview
1.5KE130CA from Taiwan Semiconductor is a bidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, designed for high-energy surge protection in automotive and industrial power rails. It features a nominal breakdown voltage of 130V, clamping voltage of 179V at 8.7A peak impulse current, and meets ISO 7637-2 Pulse 1/2a/2b/3a/3b immunity requirements for vehicle electronics.
For engineers reviewing the 1.5KE130CA datasheet, 1.5KE130CA pinout, 1.5KE130CA application, or 1.5KE130CA equivalent, this device is selected for robust ESD and load-dump transient suppression where bidirectional clamping, low dynamic impedance (<1Ω), and AEC-Q101 qualification are required - especially in 12V/24V automotive subsystems, DC power supplies, and industrial I/O protection circuits.
Technical Context
The 1.5KE130CA operates as a bidirectional avalanche diode with symmetrical clamping behavior in both polarities, enabling protection of AC-coupled or floating signal/power lines without polarity constraints. Its 10/1000μs waveform surge rating of 1500W and fast response time (<5.0ns) ensure effective suppression of fast transients including EFT and inductive switching spikes.
It exhibits a temperature coefficient of VBR of 0.107%/°C and maintains stable clamping performance across –55°C to +175°C junction temperature range. The device complies with RoHS and halogen-free standards (IEC 61249-2-21), and its DO-201 package supports lead-free soldering per J-STD-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 124V / 137V at 1.0mA test current - defines reliable conduction onset under surge conditions |
| VWM | 111V - maximum continuous reverse working voltage before leakage exceeds 1µA |
| VC @ IPP | 179V at 8.7A peak impulse current - clamping voltage limiting downstream component stress |
| PPK | 1500W - peak pulse power handling capability for 10/1000μs transients |
| IPP | 8.7A - maximum non-repetitive surge current the device safely clamps |
| TJ max | +175°C - enables operation in under-hood automotive environments and high-temperature industrial enclosures |
| Package | DO-201 - industry-standard axial-leaded package with UL 94V-0 molding compound and tin-plated leads |
Pinout & Package
DO-201 package: axial-leaded, cylindrical epoxy body with cathode band marking for unidirectional variants; 1.5KE130CA is bidirectional and marked with part-specific code (no polarity band). 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 / Cathode (symmetrical) | Bidirectional avalanche junction terminals | No functional polarity - either terminal serves as anode or cathode depending on transient polarity; enables AC-line or floating-rail protection without orientation constraints |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JEDEC standard |
| ISO 7637-2 compliance | Withstands Pulse 1 (inductive load dump), Pulse 2a/2b (battery disconnect), and Pulse 3a/3b (EFT) waveforms without degradation |
| Low dynamic impedance | <1Ω typical - minimizes voltage overshoot during high-di/dt surges by sustaining low clamping impedance across full IPP range |
| Fast response time | <5.0ns - ensures clamping activation before transient energy damages downstream ICs or MOSFETs |
| Halogen-free & RoHS | Meets IEC 61249-2-21 and EU RoHS Directive - suitable for environmentally regulated industrial and automotive production |

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 SMAJ130CA | Same 130V nominal, DO-214AC (SMA) package, 1500W rating, but lower IPP (8.3A) and higher VC (187V) | Surface-mount only; requires PCB rework vs. through-hole DO-201 of 1.5KE130CA | Select when board space is constrained and SMT assembly is preferred; verify thermal pad layout for equivalent power dissipation. |
| ON Semiconductor 1.5SMC130CA | Identical electrical specs (VBR, VC, PPK) but in DO-214AB (SMC) package; slightly higher VWM (113V vs. 111V) | Higher thermal mass than DO-201; better for repeated surge duty cycles in industrial motor drives | Choose for enhanced thermal endurance in high-duty-cycle environments; confirm mechanical fit in existing DO-201 footprint. |
Compared with SMAJ130CA and 1.5SMC130CA, the 1.5KE130CA offers through-hole DO-201 mounting for high-reliability mechanical retention and simplified prototyping, while maintaining identical clamping performance and AEC-Q101 qualification - making it optimal for automotive module repair, legacy industrial designs, and manual assembly scenarios.

FAQ
What is the clamping voltage of the 1.5KE130CA at its rated peak current?
The 1.5KE130CA has a maximum clamping voltage (VC) of 179V at 8.7A peak impulse current (IPP) under the standard 10/1000μs waveform. This value is measured per JEDEC test conditions and ensures downstream components experience no more than 179V during worst-case surge events, directly supporting system-level overvoltage immunity design.
Is the 1.5KE130CA suitable for automotive applications?
Yes, the 1.5KE130CA is AEC-Q101 qualified and explicitly tested to meet ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b transient immunity standards. Its DO-201 package, –55°C to +175°C operating range, and robust surge handling make it suitable for engine control units, body electronics, and infotainment power inputs in passenger and commercial vehicles.
How does the 1.5KE130CA differ from the unidirectional 1.5KE130C?
The 1.5KE130CA is bidirectional, providing symmetrical clamping for both positive and negative transients, whereas the 1.5KE130C is unidirectional and requires correct polarity installation. The "CA" suffix denotes bidirectional functionality - critical for AC-coupled lines, floating grounds, or circuits where voltage polarity reversal may occur during faults.
What is the maximum working voltage (VWM) for the 1.5KE130CA?
The 1.5KE130CA has a maximum working stand-off voltage (VWM) of 111V DC. This means it remains in high-impedance state with leakage <1µA up to 111V, allowing safe operation on 100V nominal DC systems such as 24V automotive buses with ripple or 96V industrial supplies with margin.
Does the 1.5KE130CA require a heatsink for 1500W surge handling?
No heatsink is required for single-event 1500W surge handling, as energy absorption occurs in milliseconds. However, for repetitive surges or elevated ambient temperatures (>75°C), derating per Fig.2 in the datasheet applies - the device's 5W steady-state power rating at TL = 75°C assumes a 0.6" × 0.6" copper pad, not forced-air or external heatsinking.
