Product details
Overview
1.5KE100CHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 100 V breakdown voltage (VBR = 95.0–105 V), 85.5 V maximum standoff voltage (VWM), 137 V clamping voltage at 10.9 A peak pulse current, 1500 W peak pulse power rating (10/1000 µs), and operates across –55 °C to +175 °C junction temperature range - deployed in automotive power supply inputs and industrial sensor interfaces.
For engineers reviewing the 1.5KE100CHE3/54 datasheet, 1.5KE100CHE3/54 pinout, 1.5KE100CHE3/54 application, or 1.5KE100CHE3/54 equivalent, this page delivers verified electrical parameters, JEDEC-standard 1.5KE package details, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), and design-meaningful clamping behavior for surge immunity validation.
Technical Context
This TVS diode uses a glass-passivated silicon junction optimized for fast transient response (<1 ns) and low incremental surge resistance. Its unidirectional polarity enables cathode-grounded placement on positive-rail protection paths, with VF = 3.5 V at 100 A forward surge and ID ≤ 1.0 µA at VWM, ensuring minimal leakage during normal operation.
The device complies with JEDEC standard 1.5KE case style and supports 13" paper tape & reel packaging (E3/54). It is RoHS-compliant and AEC-Q101 qualified (HE3 suffix), meeting automotive-grade reliability requirements for under-hood and body-control module applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 95.0 V / 105 V - defines minimum voltage at which clamping initiates reliably under 1 mA test current |
| VWM | 85.5 V - maximum continuous operating voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 137 V - clamped voltage seen by protected circuit during 10.9 A 10/1000 µs surge |
| PPPM | 1500 W - peak transient power it can absorb without failure (10/1000 µs waveform) |
| IFSM | 200 A - non-repetitive forward surge capability (8.3 ms half-sine wave) |
| TJ max. | +175 °C - enables use in high-temperature engine-bay environments without derating |
| RθJA | 75 °C/W - thermal resistance from junction to ambient; informs heatsinking needs for sustained surge duty |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A | Lower PPPM (600 W), smaller SMB package (3.5 mm × 4.5 mm), VC = 162 V @ 3.7 A | Better suited for space-constrained PCBs but insufficient for ISO 7637-2 Pulse 5a compliance | Select when board area is critical and surge energy is limited to IEC 61000-4-5 Level 2 |
| 1.5SMC100A | Same PPPM (1500 W), SMC package (7.1 mm × 6.2 mm), VC = 137 V @ 10.9 A, identical electrical specs | Surface-mount alternative requiring rework of footprint and solder profile | Choose for automated assembly where through-hole mounting is impractical |
Compared with SMBJ100A and 1.5SMC100A, the 1.5KE100CHE3/54 offers proven axial-leaded robustness for high-energy automotive transients, while maintaining identical clamping performance to 1.5SMC100A - making it optimal for legacy through-hole designs requiring AEC-Q101 validation and field-proven surge endurance.

FAQ
What is the clamping voltage of the 1.5KE100CHE3/54 under a 10/1000 µs surge?
The 1.5KE100CHE3/54 clamps to a maximum of 137 V when subjected to its rated peak pulse current of 10.9 A (10/1000 µs waveform). This value is measured per JEDEC test conditions and ensures protected downstream circuitry remains below destructive voltage thresholds during standardized surge events.
Is the 1.5KE100CHE3/54 qualified for automotive applications?
Yes, the 1.5KE100CHE3/54 carries the HE3 suffix, confirming it is AEC-Q101 qualified. This certification covers stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing - validating its suitability for under-hood and body-control module deployments.
What does the "HE3/54" suffix mean in 1.5KE100CHE3/54?
The "HE3" denotes RoHS compliance and AEC-Q101 qualification; "54" specifies the preferred package code for 13-inch paper tape and reel delivery containing 1400 units. This ordering format ensures traceable, automotive-grade logistics and automated assembly compatibility.
How does the 1.5KE100CHE3/54 compare to bidirectional variants like 1.5KE100C?
The 1.5KE100CHE3/54 is unidirectional and intended for DC rail protection with polarity-sensitive placement (cathode to ground). In contrast, 1.5KE100C is bidirectional and used for AC or floating-line protection. They share identical VBR, VC, and PPPM, but differ in polarity handling and marking - no direct substitution without circuit review.
What is the maximum junction temperature rating for the 1.5KE100CHE3/54?
The 1.5KE100CHE3/54 has a maximum junction temperature (TJ) rating of +175 °C, enabling reliable operation in high-ambient environments such as engine compartments or enclosed industrial enclosures without thermal derating up to that limit.
