Product details
Overview
1.5KE13CAHE3_B/C from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode designed for clamping voltage transients on signal and power lines. It features a 13 V nominal breakdown voltage (VBR = 12.4–13.7 V at 1.0 mA), 1500 W peak pulse power (10/1000 µs), and clamps to ≤18.2 V at 82.4 A peak pulse current - used in automotive sensor protection, industrial I/O interfaces, and telecom line surge suppression.
For engineers reviewing the 1.5KE13CAHE3_B/C datasheet, 1.5KE13CAHE3_B/C pinout, 1.5KE13CAHE3_B/C application, or 1.5KE13CAHE3_B/C equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, AEC-Q101 qualification status, clamping performance curves, and direct alternative part comparisons - all grounded in Vishay Document #88301 (Rev. 09-Aug-2022).
Technical Context
This bidirectional TVS operates symmetrically in both polarities with no polarity marking, enabling AC-coupled or floating-line protection without orientation concerns. Its glass-passivated junction ensures stable VBR tolerance (±5%), low incremental surge resistance, and fast sub-nanosecond response time - critical for safeguarding MOSFET gates and microcontroller I/O against ESD and lightning-induced surges.
The device complies with UL 497B (QVGQ2 recognition) and meets JESD 201 Class 2 whisker resistance (HE3 suffix). It is rated for -55 °C to +175 °C operation, supports 10/1000 µs waveform testing per R.E.A., and derates linearly above 25 °C ambient using a 75 °C/W junction-to-ambient thermal resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4 V / 13.7 V at 1.0 mA - defines precise clamping onset threshold for bidirectional overvoltage events |
| VWM | 11.1 V - maximum continuous working voltage before leakage exceeds 5 µA; sets safe operating margin below breakdown |
| VC @ IPPM | ≤18.2 V at 82.4 A - actual clamped voltage during 1500 W transient, limiting stress on downstream ICs |
| PPPM | 1500 W (10/1000 µs) - peak surge energy handling capacity compatible with IEC 61000-4-5 Level 4 requirements |
| IPPM | 82.4 A - peak pulse current capability determines minimum series impedance needed for effective protection |
| TJ max. | +175 °C - high junction temperature rating enables use in under-hood automotive and industrial environments |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13CA | DO-214AA package (smaller footprint), 600 W PPPM, same VBR range (12.4–13.7 V), higher capacitance (~150 pF vs. ~50 pF) | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4; preferred where board space is constrained | Select SMBJ13CA only if surge energy is ≤600 W and layout cannot accommodate DO-201AD body size. |
| 1.5SMC13CA | DO-214AB package, identical 1500 W rating and VBR, but non-AEC-Q101; standard E3 suffix only (no HE3 qualification) | Acceptable for commercial/industrial use but not automotive; lacks automotive reliability validation and whisker resistance class | Choose 1.5SMC13CA for cost-sensitive non-automotive designs where AEC-Q101 is not mandated. |
Compared with 1.5KE13CAHE3_B/C, SMBJ13CA trades surge capacity for compactness, while 1.5SMC13CA matches power rating but omits automotive qualification - making 1.5KE13CAHE3_B/C the sole option meeting AEC-Q101, UL 497B, and 1500 W requirements in a single device.

FAQ
What is the breakdown voltage tolerance of the 1.5KE13CAHE3_B/C?
The 1.5KE13CAHE3_B/C has a guaranteed breakdown voltage range of 12.4 V to 13.7 V at 1.0 mA test current, representing a ±5% tolerance around the nominal 13 V rating. This tight VBR window ensures predictable clamping behavior in bidirectional protection circuits and is maintained across the full operating temperature range (-55 °C to +175 °C).
Is the 1.5KE13CAHE3_B/C suitable for automotive applications?
Yes, the 1.5KE13CAHE3_B/C is AEC-Q101 qualified (per Note 2 on page 3 of Vishay Document #88301), confirming its suitability for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. The HE3_B/C suffix explicitly denotes AEC-Q101 qualification and JESD 201 Class 2 whisker resistance.
How does the clamping voltage of the 1.5KE13CAHE3_B/C compare to its breakdown voltage?
The 1.5KE13CAHE3_B/C clamps to ≤18.2 V at its rated peak pulse current of 82.4 A, which is approximately 40% above its minimum breakdown voltage of 12.4 V. This controlled voltage overshoot ensures downstream components experience minimal overvoltage stress while maintaining sufficient margin to avoid false triggering during normal operation.
What is the maximum operating temperature for the 1.5KE13CAHE3_B/C?
The 1.5KE13CAHE3_B/C has a maximum junction temperature (TJ) of +175 °C and an operating storage temperature range of -55 °C to +175 °C. This wide thermal envelope supports deployment in under-hood automotive locations, industrial motor drives, and outdoor telecom equipment without derating until ambient exceeds 25 °C.
Does the 1.5KE13CAHE3_B/C require polarity-aware PCB layout?
No - the 1.5KE13CAHE3_B/C is a bidirectional TVS diode with no polarity marking on the DO-201AD package. Its symmetrical construction allows installation across any two-point voltage differential without regard to lead orientation, simplifying assembly and eliminating risk of reverse-mounting errors in high-volume manufacturing.
