Product details
Overview
1.5KE13CAHE3/51 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in signal and power lines. It features a 13 V breakdown voltage (VBR min/max = 12.4–13.7 V at 1.0 mA), 11.1 V stand-off voltage (VWM), 18.2 V clamping voltage (VC at 82.4 A), 1500 W peak pulse power (10/1000 µs), and AEC-Q101 qualification - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the 1.5KE13CAHE3/51 datasheet, 1.5KE13CAHE3/51 pinout, 1.5KE13CAHE3/51 application, or 1.5KE13CAHE3/51 equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, bi-directional clamping behavior, thermal derating curves, and direct alternatives with documented differences in VBR, VC, and qualification status.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, with identical VBR, VWM, IPPM, and VC specifications in forward and reverse directions. Its glass-passivated junction enables sub-nanosecond response time (<1 ns) and low incremental surge resistance - critical for protecting fast-edge digital interfaces against ESD and lightning-induced transients.
The device is rated for 1500 W peak pulse power under 10/1000 µs waveform, with thermal resistance RθJL = 15.4 °C/W and RθJA = 75 °C/W. It supports continuous operation from –55 °C to +175 °C junction temperature and meets JESD 201 Class 2 whisker resistance (HE3 suffix).

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13CA | DO-214AA package (SMB), lower PPPM = 600 W, VC = 21.5 V at 27.8 A, same VBR range (12.4–13.7 V) | Surface-mount only; unsuitable for high-energy 1500 W transients but ideal for space-constrained PCBs with moderate surge exposure | Select SMBJ13CA when board area is constrained and peak surge energy is ≤600 W - not a drop-in replacement due to package and power rating mismatch |
| 1.5KE13CA-E3/54 | Same DO-201AD package and electrical specs, but commercial-grade (non-AEC-Q101), HE3 suffix replaced by E3 (JESD 201 Class 1A) | Lacks automotive qualification; acceptable for industrial/commercial equipment where AEC-Q101 is not mandated | Choose 1.5KE13CA-E3/54 for cost-sensitive non-automotive designs requiring identical clamping performance without qualification overhead |
Compared with 1.5KE13CAHE3/51, SMBJ13CA trades 1500 W capability for SMT compatibility and smaller footprint, while 1.5KE13CA-E3/54 retains full electrical equivalence but omits AEC-Q101 validation - making the HE3 variant uniquely suited for automotive safety-critical signal protection.

FAQ
What does the 'CA' suffix indicate in 1.5KE13CAHE3/51?
The 'CA' suffix in 1.5KE13CAHE3/51 denotes a bi-directional configuration - meaning the device provides symmetrical transient suppression in both polarities, with identical breakdown, clamping, and leakage characteristics regardless of voltage polarity applied across its terminals. This eliminates the need for polarity-aware placement on PCBs and ensures protection against both positive and negative transients without additional components.
Is 1.5KE13CAHE3/51 suitable for IEC 61000-4-5 compliance testing?
Yes, 1.5KE13CAHE3/51 is suitable for IEC 61000-4-5 compliance testing as a primary or secondary protection device. Its 1500 W peak pulse power rating (10/1000 µs waveform), 18.2 V clamping voltage at 82.4 A, and low dynamic impedance enable effective suppression of combination wave surges up to 4 kV (line-earth) and 2 kV (line-line) - provided external series impedance and layout follow IEC-recommended practices.
How does the HE3 suffix differ from E3 in Vishay TVS part numbering?
The HE3 suffix in 1.5KE13CAHE3/51 indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas E3 denotes RoHS compliance and JESD 201 Class 1A whisker resistance without automotive qualification. The HE3 variant is validated for automotive under-hood use, while E3 is intended for commercial/industrial applications where AEC-Q101 is not required.
What is the maximum allowable lead temperature during soldering for 1.5KE13CAHE3/51?
The maximum allowable lead temperature for 1.5KE13CAHE3/51 is 275 °C for up to 10 seconds, per JESD 22-B106. This specification applies to dip soldering only; for reflow or hand-soldering, Vishay recommends adhering to JEDEC J-STD-020 moisture sensitivity level (MSL) guidelines and avoiding sustained temperatures above 260 °C to prevent internal delamination or junction degradation.
Can 1.5KE13CAHE3/51 be used in parallel to increase surge current handling?
Yes, 1.5KE13CAHE3/51 can be used in parallel to increase total surge current capacity, but only with careful attention to matching - devices must be from the same manufacturing lot to ensure balanced current sharing. Mismatched VBR or dynamic impedance may cause one unit to absorb disproportionate energy, leading to premature failure. For higher power needs, Vishay recommends selecting a single higher-rated device (e.g., 3.0KE series) instead of paralleling.
