Product details

Overview

1.5KE13C from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with 13V nominal breakdown voltage (V_BR = 11.7–14.3V @ 1.0mA), 10.5V working stand-off voltage (V_WM), and 19.0V maximum clamping voltage (V_C @ I_PP = 82A) - designed to protect automotive power rails and industrial sensor interfaces against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.

For engineers reviewing the 1.5KE13C datasheet, 1.5KE13C pinout, 1.5KE13C application, or 1.5KE13C equivalent, this page delivers verified electrical parameters, DO-201 terminal polarity mapping, AEC-Q101 qualification status, clamping performance at 10/1000μs waveform, and real-world use cases for ESD and inductive switching surge protection.

Technical Context

The 1.5KE13C operates as a unidirectional avalanche diode with fast response time (<1.0ps from 0V to V_BR) and low dynamic impedance, enabling effective suppression of high-energy transients without circuit interruption. Its junction temperature range spans −55°C to +175°C, supporting under-hood automotive deployment.

It meets ISO 7637-2 immunity requirements for automotive electronics and complies with RoHS and halogen-free standards (IEC 61249-2-21). The device features pure tin-plated leads, UL 94V-0 molding compound, and JESD 201 Class 2 whisker resistance.

Equivalent & Alternatives

The following parts are listed as comparable options for similar transient voltage suppression applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SMCJ13A	Surface-mount SMC package (vs. DO-201 axial); same 13V V_BR, but lower P_PK = 1500W and V_C = 21.5V @ 70A.	Requires PCB redesign for SMT placement; better suited for space-constrained boards where reflow is preferred over wave soldering.	Select SMCJ13A only if board layout supports SMT and thermal management allows for reduced surge margin.
1N6274A	Same manufacturer, same DO-201 package, tighter V_BR tolerance (12.4–13.7V vs. 11.7–14.3V); identical V_C = 18.2V @ 86A.	No change in application scope - direct functional replacement with improved voltage consistency for precision clamping.	Choose 1N6274A when tighter breakdown voltage control is required for robustness across temperature and production lot variation.

Compared with 1.5KE13C, SMCJ13A trades axial through-hole compatibility for SMT footprint efficiency but sacrifices clamping performance (21.5V vs. 19.0V), while 1N6274A offers identical packaging and superior V_BR tolerance without altering system design or thermal constraints.

FAQ

What is the clamping voltage of the 1.5KE13C under a standard 10/1000μs surge?

The 1.5KE13C clamps to a maximum of 19.0 V when subjected to its rated peak impulse current of 82 A under the 10/1000 μs waveform. This value is measured per JEDEC test conditions and guarantees that protected circuits experience no more than 19.0 V during such transients - critical for safeguarding 24 V-tolerant ICs in automotive and industrial applications. The 1.5KE13C achieves this with low dynamic impedance and sub-nanosecond response.

Is the 1.5KE13C AEC-Q101 qualified?

Yes, the 1.5KE13C is AEC-Q101 qualified when ordered with the "H" suffix (e.g., 1.5KE13CH). Standard 1.5KE13C parts may not carry full AEC-Q101 certification unless explicitly marked; verification requires checking the ordering code and TSC's official qualification reports. AEC-Q101 validation covers stress tests including HTGB, H3TRB, and ESD, confirming suitability for automotive powertrain and chassis systems. Always specify 1.5KE13CH for certified automotive use.

What is the maximum working voltage (V_WM) for the 1.5KE13C?

The 1.5KE13C has a maximum working stand-off voltage (V_WM) of 10.5 V - the highest DC or RMS voltage that can be continuously applied without exceeding 1 µA leakage current. This value ensures safe operation on 12 V nominal systems with typical ripple and tolerance margins, while retaining sufficient headroom (≥1.2× V_WM) to avoid premature conduction during normal operation. Exceeding 10.5 V risks increased leakage and accelerated aging of the 1.5KE13C.

How does the 1.5KE13C differ from the 1.5KE13A variant?

The 1.5KE13A variant features a tighter breakdown voltage range (12.4–13.7 V) compared to the 1.5KE13C (11.7–14.3 V), achieved via enhanced binning during manufacturing. Both share identical package (DO-201), clamping voltage (18.2 V vs. 19.0 V), and surge rating (1500 W), but the 1.5KE13A offers improved consistency for designs requiring precise clamping thresholds. The 1.5KE13C remains optimal for cost-sensitive, high-volume applications where broader V_BR tolerance is acceptable.

Can the 1.5KE13C be used in bidirectional configurations?

No - the 1.5KE13C is a unidirectional TVS diode, intended for DC-biased lines where polarity is fixed (e.g., 12 V rail to ground). For bidirectional protection (e.g., AC lines or differential buses like RS-485), a dedicated bidirectional part such as 1.5KE13CA must be used. Using two 1.5KE13C devices in series opposition is not recommended due to mismatched V_BR tolerances and undefined behavior under reverse surge; the 1.5KE13C datasheet explicitly specifies unidirectional operation only.
