Product details
Overview
1.5KE100AHE3_B/C from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection of DC power rails and signal lines. It features a 95.0 V to 105 V breakdown voltage (VBR), 85.5 V maximum working peak reverse voltage (VWM), 137 V clamping voltage at 10.9 A peak pulse current (IPPM), 1500 W peak pulse power (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 1.5KE100AHE3_B/C datasheet, 1.5KE100AHE3_B/C pinout, 1.5KE100AHE3_B/C application, or 1.5KE100AHE3_B/C equivalent, key selection criteria include verified clamping performance under 10/1000 µs surge, unidirectional polarity with cathode band marking, AEC-Q101 qualification status, and compatibility with JEDEC case style 1.5KE through-hole package for high-reliability board-level surge immunity.
Technical Context
This TVS diode employs a glass passivated silicon junction optimized for fast transient response (<1 ns) and low incremental surge resistance. Its clamping behavior is characterized by a 0.106 %/°C temperature coefficient of VBR, enabling stable protection across wide thermal ranges without external biasing.
The device delivers 1500 W peak pulse power handling per 10/1000 µs waveform at 0.01 % duty cycle, with derating above 25 °C ambient per Fig. 2 and thermal resistance of 15.4 °C/W (junction-to-lead), supporting robust operation in constrained thermal environments when mounted on standard PCB copper pours.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 95.0 V / 105 V - ensures reliable conduction onset above normal operating voltage while avoiding false triggering |
| VWM | 85.5 V - maximum continuous reverse voltage before leakage exceeds 1 µA, defining safe DC operating margin |
| VC @ IPPM | 137 V - clamped voltage during 10.9 A 10/1000 µs surge, limiting stress on downstream ICs |
| PPPM | 1500 W - peak transient energy absorption capacity, sufficient for IEC 61000-4-5 Level 4 surges |
| IFSM | 200 A - 8.3 ms half-sine forward surge rating, supporting inrush and fault-current events |
| TJ max. | +175 °C - extended junction temperature enables use in under-hood automotive and high-ambient industrial locations |

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 | Surface-mount SMB package; 100 V VBR min (95–105 V same); 1000 W PPPM; 10.5 A IPPM | Lower power rating; suited for space-constrained PCBs where thermal mass is limited | Select when automated SMT assembly is required and surge energy does not exceed 1000 W |
| 1.5KE100A-E3/54 | Same 1.5KE through-hole package; identical electrical specs; commercial-grade (non-AEC-Q101) | Lacks automotive qualification; suitable for industrial/commercial power supplies only | Choose for cost-sensitive non-automotive designs where AEC-Q101 is not mandated |
Compared with 1.5KE100AHE3_B/C, SMBJ100A-E3/52 trades 33 % lower surge power for SMT compatibility, while 1.5KE100A-E3/54 retains identical protection performance but omits AEC-Q101 validation - making the HE3 variant essential for automotive Tier 1 supply chain compliance.

FAQ
What is the clamping voltage of the 1.5KE100AHE3_B/C under a standard 10/1000 µs surge?
The 1.5KE100AHE3_B/C clamps to a maximum of 137 V when subjected to its rated 10.9 A peak pulse current (IPPM) under a 10/1000 µs waveform. This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring downstream components like 100 V-rated MOSFETs remain within safe operating area. The 137 V clamping voltage is guaranteed across the full operating temperature range.
Is the 1.5KE100AHE3_B/C qualified for automotive applications?
Yes, the 1.5KE100AHE3_B/C is AEC-Q101 qualified, as confirmed in Vishay's datasheet revision 09-Aug-2022 (Document Number: 88301), footnote (2). This qualification covers the HE3_B/C variant specifically and validates its reliability for use in automotive powertrain, chassis, and body electronics where sustained operation at 175 °C junction temperature and resistance to mechanical shock, thermal cycling, and humidity are mandatory. The "HE3" suffix denotes AEC-Q101 compliance.
How does the 1.5KE100AHE3_B/C differ from the 1.5KE100A-E3/54?
The 1.5KE100AHE3_B/C and 1.5KE100A-E3/54 share identical electrical specifications (VBR, VWM, VC, PPPM) and JEDEC 1.5KE package, but differ in qualification and marking. The HE3_B/C variant is AEC-Q101 qualified and marked with "HE3_B/C", whereas the E3/54 version is commercial-grade only. Both use RoHS-compliant matte tin plating, but only HE3_B/C meets JESD 201 Class 2 whisker testing - a requirement for automotive production.
What is the maximum reverse leakage current of the 1.5KE100AHE3_B/C at its working voltage?
At its maximum working peak reverse voltage (VWM) of 85.5 V and ambient temperature of 25 °C, the 1.5KE100AHE3_B/C exhibits a maximum reverse leakage current (ID) of 1.0 µA. This low leakage ensures minimal power loss in always-on systems and prevents false triggering in high-impedance sensing circuits - a key advantage over higher-leakage alternatives that could compromise battery life or signal accuracy in precision analog front-ends.
Can the 1.5KE100AHE3_B/C be used in bidirectional protection configurations?
No, the 1.5KE100AHE3_B/C is a unidirectional TVS diode, indicated by the "A" suffix (not "CA"). It conducts only in reverse breakdown and blocks forward current up to 3.5 V. For bidirectional protection, Vishay specifies variants with "CA" suffix (e.g., 1.5KE100CA), which internally integrate two opposing diodes. Using 1.5KE100AHE3_B/C in bidirectional applications would leave positive transients unprotected - correct implementation requires either a CA-series part or external series/parallel diode pairing.
