Product details
Overview
1.5KE100CHE3/73 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 interface protection.
For engineers reviewing the 1.5KE100CHE3/73 datasheet, 1.5KE100CHE3/73 pinout, 1.5KE100CHE3/73 application, or 1.5KE100CHE3/73 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJL = 15.4 °C/W), JEDEC 1.5KE package dimensions, and real-world clamping behavior under lightning-surge and inductive-switching transients.
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 asymmetric clamping on DC-biased lines, with forward conduction limited to 3.5 V at 100 A and reverse leakage ≤1.0 µA at VWM.
The device complies with JEDEC standard test waveforms (10/1000 µs, 8/20 µs), supports repetitive surge duty cycles up to 0.01 %, and is rated for 200 A non-repetitive forward surge (8.3 ms half-sine). Thermal performance is characterized by RθJA = 75 °C/W and RθJL = 15.4 °C/W, enabling reliable operation without heatsinking in moderate-power applications.
Key Specifications

IC Role / Device Role / Timing Role: Unidirectional TVS connected between signal line and local ground, absorbing ±2 kV HBM ESD events. Use Value: Maintains signal integrity below 100 mV error during clamping, with leakage <1 µA at 24 V nominal line voltage. |
| Telecom DC Power Feeds | Consumer Appliance Motor Drive Protection |
Use Scenario: Safeguarding PoE-powered network switches against induced surges on 48 V DC distribution lines. IC Role / Device Role / Timing Role: Standoff-rated TVS on secondary-side DC bus, triggered only during >85.5 V transients. Use Value: Prevents latch-up in PMICs and Ethernet PHYs while drawing zero quiescent current during normal 48 V operation. | Use Scenario: Suppressing back-EMF spikes from brushed DC motors in washing machines and HVAC blowers. IC Role / Device Role / Timing Role: Mounted across motor terminals to clamp inductive turn-off spikes before reaching MCU GPIOs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A-E3/52 | Lower PPPM (600 W), SMC package, VC = 165 V @ 3.6 A | Not AEC-Q101 qualified; suited for space-constrained consumer PCBs, not under-hood use | Select when board area is critical and surge energy is ≤600 W; verify layout thermal relief for SMB package |
| 1.5KE100A-E3/73 | Same electrical specs but commercial-grade (non-AEC-Q101); identical 1.5KE package and pinout | Lacks automotive qualification; acceptable for industrial control panels with no automotive certification requirement | Choose for cost-sensitive non-automotive designs where AEC-Q101 is not mandated |
Compared with 1.5KE100CHE3/73, SMBJ100A-E3/52 trades peak power and qualification for compactness, while 1.5KE100A-E3/73 offers identical protection performance without automotive validation - enabling direct substitution where qualification is not required.

FAQ
What is the clamping voltage of the 1.5KE100CHE3/73 under a 10/1000 µs surge?
The 1.5KE100CHE3/73 clamps to a maximum of 137 V at its rated peak pulse current of 10.9 A under the standardized 10/1000 µs waveform. This value is guaranteed across temperature and production lot, ensuring predictable protection margin for 100 V-rated downstream components. The clamping occurs within <1 ns of transient onset, minimizing voltage overshoot before conduction begins.
Is the 1.5KE100CHE3/73 qualified for automotive applications?
Yes, the 1.5KE100CHE3/73 carries the HE3 suffix, indicating full AEC-Q101 qualification per Vishay's documentation. It has passed stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing - making it suitable for engine control units, body modules, and other automotive subsystems requiring certified surge protection.
How does the 1.5KE100CHE3/73 differ from the 1.5KE100A-E3/73?
The 1.5KE100CHE3/73 and 1.5KE100A-E3/73 share identical electrical specifications and JEDEC 1.5KE packaging, but only the HE3 version is AEC-Q101 qualified. The "H" in HE3 denotes automotive qualification, while the "E3" indicates RoHS-compliant matte tin plating. For non-automotive industrial use, the 1.5KE100A-E3/73 is a functionally equivalent, lower-cost alternative.
What is the maximum reverse leakage current of the 1.5KE100CHE3/73 at its standoff voltage?
At its maximum working voltage (VWM = 85.5 V) and ambient temperature of 25 °C, the 1.5KE100CHE3/73 exhibits a maximum reverse leakage current of 1.0 µA. This ultra-low leakage ensures minimal power loss in always-on systems and prevents false triggering in high-impedance sensor circuits.
Can the 1.5KE100CHE3/73 be used in bidirectional configurations?
No - the 1.5KE100CHE3/73 is a unidirectional TVS diode, as confirmed by its part number suffix "A" (not "CA"). Bidirectional variants such as 1.5KE100CAHE3/73 exist for AC-coupled or floating-line protection, but the 1.5KE100CHE3/73 must be oriented with cathode toward the protected line to function correctly in DC applications.
