Product details
Overview
1.5KE150CHE3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for high-energy surge protection in DC power rails and signal lines. It features a 1500 W peak pulse power rating (10/1000 µs), 143 V minimum breakdown voltage (VBR), 128 V maximum standoff voltage (VWM), and clamps transients to ≤207 V at 7.2 A peak pulse current - deployed in automotive power supply inputs and industrial sensor interface protection.
For engineers reviewing the 1.5KE150CHE3/73 datasheet, 1.5KE150CHE3/73 pinout, 1.5KE150CHE3/73 application, or 1.5KE150CHE3/73 equivalent, this part delivers verified AEC-Q101 qualification, glass-passivated junction reliability, and low incremental surge resistance for robust ESD and lightning-induced transient suppression in harsh environments.
Technical Context
This TVS diode operates as a voltage-clamping device with avalanche breakdown behavior, triggered when reverse voltage exceeds its specified VBR range (143–158 V). Its response time is effectively instantaneous (<1 ns), enabling protection of downstream MOSFETs and ICs against fast-rising transients from inductive switching or EFT events.
Thermal performance is defined by RθJA = 75 °C/W and RθJL = 15.4 °C/W, supporting operation up to TJ = 175 °C. The device uses a molded epoxy case (UL 94 V-0 rated) with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150A-E3/52 | Lower peak power (600 W), smaller SMB package (3.5 mm × 4.5 mm), higher VC/VBR ratio (1.45× vs. 1.45×) | Preferred for space-constrained PCBs where 600 W suffices; not suitable for ISO 7637-2 Pulse 5a compliance | Select when board area is critical and surge energy is limited to <600 W; verify thermal derating at 75 °C ambient |
| 1.5KE150A-E3/73 | Same electrical specs but commercial-grade (non-AEC-Q101), no HE3 qualification marking | Acceptable for industrial or consumer use where automotive qualification is not mandated | Choose for cost-sensitive non-automotive designs requiring identical clamping performance without AEC validation overhead |
Compared with 1.5KE150CHE3/73, SMBJ150A-E3/52 trades peak power and thermal robustness for compactness, while 1.5KE150A-E3/73 retains full electrical equivalence but omits automotive qualification - making the HE3 variant essential for Tier-1 automotive BOMs requiring traceable AEC-Q101 evidence.

FAQ
What is the exact breakdown voltage range for 1.5KE150CHE3/73?
The 1.5KE150CHE3/73 has a minimum breakdown voltage (VBR) of 143 V and a maximum of 158 V, measured at 1 mA test current per the Vishay datasheet (Document Number: 88301). This range ensures consistent clamping behavior across production lots and temperature extremes from −55 °C to +175 °C. The 1.5KE150CHE3/73 maintains this specification under JEDEC-standard test conditions and is validated for AEC-Q101 compliance.
Is 1.5KE150CHE3/73 unidirectional or bidirectional?
The 1.5KE150CHE3/73 is a unidirectional TVS diode, indicated by the "A" suffix (not "CA"). Its cathode is marked with a color band, and it conducts only in reverse bias above VBR. Unlike bidirectional variants (e.g., 1.5KE150CA), the 1.5KE150CHE3/73 does not suppress positive transients on grounded lines - it is intended for DC rail protection where polarity is fixed and ground-referenced clamping is required.
Does 1.5KE150CHE3/73 meet AEC-Q101 requirements?
Yes, the "HE3" suffix in 1.5KE150CHE3/73 explicitly denotes AEC-Q101 qualification per Vishay's ordering nomenclature and datasheet notes. This includes stress testing for temperature cycling, highly accelerated life testing (HALT), and ESD per AEC-Q101 Rev D. The 1.5KE150CHE3/73 is approved for automotive powertrain and body electronics applications where qualification evidence is mandatory.
What is the clamping voltage of 1.5KE150CHE3/73 at rated peak current?
At its rated peak pulse current (IPPM) of 7.2 A (10/1000 µs waveform), the 1.5KE150CHE3/73 clamps to a maximum of 207 V. This value is guaranteed per the Vishay datasheet and represents the upper limit of voltage imposed on protected circuitry during worst-case surge events - critical for ensuring compatibility with 200 V-rated downstream components like gate drivers and regulators.
Can 1.5KE150CHE3/73 be used in parallel for higher power handling?
While the 1.5KE150CHE3/73 datasheet states TVS diodes "can also be used in series or parallel to increase peak power ratings," parallel use requires careful matching of VBR and thermal layout to ensure current sharing. Mismatched units may cause one 1.5KE150CHE3/73 to dominate conduction and fail prematurely. For >1500 W needs, Vishay recommends using higher-rated devices (e.g., 3KP series) instead of parallel configurations.
