Product details
Overview
1.5KE13C-E3/73 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 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 1.5KE13C-E3/73 datasheet, 1.5KE13C-E3/73 pinout, 1.5KE13C-E3/73 application, or 1.5KE13C-E3/73 equivalent, this part delivers verified bidirectional clamping performance with UL 94 V-0 molded epoxy packaging, RoHS-compliant matte tin leads, and JESD 201 Class 1A whisker resistance - critical for high-reliability board-level ESD and lightning surge protection.
Technical Context
This device operates as a silicon avalanche diode with glass-passivated junction, enabling sub-nanosecond response time (<1 ns) and low incremental surge resistance. Its bidirectional architecture eliminates polarity concerns in AC-coupled or differential signal paths, and it complies with ANSI/IEEE C62.35 surge waveform standards.
Rated for -55 °C to +175 °C operating junction temperature, the 1.5KE13C-E3/73 sustains repetitive 10/1000 µs pulses at 0.01% duty cycle and derates linearly above 25 °C ambient per Fig. 2. It exhibits no marking on the body - consistent with bidirectional TVS identification per Vishay specification.

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 (SMB) package, 600 W PPPM, same VBR range (12.4–13.7 V), lower IPPM (32.8 A) | Surface-mount only; unsuitable for through-hole designs or high-current legacy layouts | Select when board space is constrained and peak surge energy is ≤600 W |
| 1.5KE13CA | Same 1.5KE package and electrical specs, but lacks E3 suffix - not RoHS-compliant or JESD 201 Class 1A qualified | Restricted to non-RoHS or non-automotive programs; incompatible with modern environmental compliance requirements | Choose only for legacy repair or non-regulated commercial applications where RoHS is waived |
Compared with 1.5KE13C-E3/73, SMBJ13CA offers compact SMT integration at reduced power handling, while 1.5KE13CA matches form/fit/function but fails modern compliance mandates - making 1.5KE13C-E3/73 the sole option for new RoHS- and AEC-Q101-aligned designs requiring 1500 W clamping.

FAQ
What is the breakdown voltage tolerance of the 1.5KE13C-E3/73?
The 1.5KE13C-E3/73 has a specified breakdown voltage range of 12.4 V to 13.7 V at 1.0 mA test current, corresponding to ±5.8% tolerance about the nominal 13 V rating. This tight VBR window ensures predictable clamping behavior across production lots and temperature extremes, directly supporting design margin calculations for protected circuits.
Is the 1.5KE13C-E3/73 suitable for automotive applications?
Yes, the 1.5KE13C-E3/73 meets AEC-Q101 qualification when ordered with the HE3 suffix (e.g., 1.5KE13CAHE3_B), but the E3/73 variant is RoHS-compliant commercial grade. For automotive use, confirm ordering code includes HE3 and revision letter; the 1.5KE13C-E3/73 itself is rated for -55 °C to +175 °C TJ and widely deployed in non-safety-critical vehicle subsystems.
Does the 1.5KE13C-E3/73 have polarity markings?
No, the 1.5KE13C-E3/73 has no color band or marking because it is a bidirectional TVS diode. Both terminals are functionally identical - the device clamps symmetrically for positive and negative transients. This eliminates orientation errors during manual or automated assembly and simplifies layout in AC-coupled or differential signal paths.
What is the maximum clamping voltage of the 1.5KE13C-E3/73 under surge conditions?
The 1.5KE13C-E3/73 clamps to a maximum of 18.2 V when subjected to its rated 82.4 A peak pulse current (10/1000 µs waveform). This value is measured per JEDEC standard and represents the worst-case voltage seen by downstream circuitry during a full 1500 W transient event - a key parameter for verifying safe operating margins of protected ICs.
Can the 1.5KE13C-E3/73 be used in parallel for higher surge current handling?
Yes, multiple 1.5KE13C-E3/73 units can be paralleled to increase total surge current capacity, but matching VBR within ±1% is recommended to ensure balanced current sharing. Vishay's application notes confirm this configuration is valid for systems exceeding 82.4 A single-device limits, provided PCB layout minimizes parasitic inductance between devices.
