Product details
Overview
1.5KE13A from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode with a nominal breakdown voltage of 13V, minimum VBR of 12.4V at 1.0mA test current, maximum clamping voltage of 18.2V at 86A peak pulse current, and DO-201 package. It protects automotive and industrial power rails against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the 1.5KE13A datasheet, 1.5KE13A pinout, 1.5KE13A application, or 1.5KE13A equivalent, this part delivers verified 1500W surge capability at 10/1000μs, sub-1ps response time from 0V to VBR, <1μA leakage above 11.1V working stand-off voltage, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
The 1.5KE13A operates as a unidirectional avalanche diode, leveraging silicon junction physics to clamp overvoltage transients by entering controlled reverse breakdown. Its 12.4–13.7V VBR range ensures precise triggering above 11.1V VWM, while low dynamic impedance maintains stable clamping under 86A IPP.
Designed for high-energy transient suppression, it sustains 1500W peak pulse power per 10/1000μs waveform, derates linearly above 25°C ambient, and meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability standards in its DO-201 molded package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR @ IT = 1.0mA | 12.4V min / 13.7V max - defines precise reverse breakdown threshold for reliable transient triggering |
| VWM | 11.1V - maximum continuous DC or RMS operating voltage before leakage exceeds 1μA |
| VC @ IPP = 86A | 18.2V - clamped voltage during full 1500W surge, limiting downstream IC stress |
| PPK | 1500W - peak pulse power handling per 10/1000μs waveform, enabling robust EFT and load-dump protection |
| IPP | 86A - maximum non-repetitive peak impulse current the device safely diverts |
| Junction Temp Range | −55°C to +175°C - supports operation in under-hood automotive and industrial environments |
| Response Time | <1.0ps - enables clamping before transient energy couples into sensitive circuitry |
Pinout & Package
DO-201 axial package with cathode band marking; two-terminal device: anode (unmarked end) and cathode (banded end). Mounting requires 0.375" (9.5mm) lead length at TL = 75°C for 5W steady-state dissipation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A | Lower 600W PPK, SMC package, 13.3V VBR min, 21.5V VC @ 28.3A | Not suitable for 1500W load-dump events; limited to lower-energy ESD/EFT scenarios | Select when board space is constrained and surge energy is ≤600W |

FAQ
What is the maximum clamping voltage of the 1.5KE13A under full-rated surge current?
The 1.5KE13A exhibits a maximum clamping voltage (VC) of 18.2V when subjected to its rated peak pulse current of 86A, measured per the 10/1000μs waveform. This value is guaranteed across temperature and ensures protected circuits remain within safe voltage limits during worst-case transients. The 1.5KE13A achieves this with low dynamic impedance and tight VBR distribution (12.4V–13.7V).
Is the 1.5KE13A suitable for bidirectional transient protection?
No, the 1.5KE13A is a unidirectional TVS diode intended for DC line protection where polarity is fixed, such as 12V automotive rails. Bidirectional protection requires a CA-suffixed variant like 1.5KE13CA. The 1.5KE13A's cathode band marking and forward voltage spec (3.5V @ 50A) confirm its unidirectional architecture; using it in AC or bipolar applications risks permanent failure.
Does the 1.5KE13A meet automotive qualification standards?
Yes, the 1.5KE13A is AEC-Q101 qualified and explicitly tested to meet ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b immunity requirements. Its construction-including pure tin-plated leads, JESD201 Class 2 whisker resistance, and −55°C to +175°C junction temperature range-supports deployment in engine control units, body control modules, and other under-hood automotive systems.
What is the working stand-off voltage (VWM) of the 1.5KE13A, and why does it matter?
The 1.5KE13A has a working stand-off voltage (VWM) of 11.1V, meaning it remains in high-impedance state with leakage <1μA up to this DC or RMS voltage. This parameter is critical for ensuring no false triggering on nominal 12V systems while allowing sufficient margin above typical rail voltage. Exceeding VWM risks premature conduction and increased power loss.
How does the 1.5KE13A compare to the 1.5KE13 (non-A) variant?
The 1.5KE13A offers tighter VBR tolerance (12.4V–13.7V) versus the standard 1.5KE13 (11.7V–14.3V), resulting in more predictable clamping onset and reduced risk of overvoltage exposure. Both share identical PPK (1500W), VC (18.2V/19.0V), and DO-201 packaging, but the "A" suffix denotes enhanced binning for mission-critical applications like automotive ECUs where voltage precision directly impacts system robustness.
