Product details
Overview
1.5KE7.5CHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection on DC power rails and signal lines. It features a 7.13 V to 7.88 V breakdown voltage (VBR) at 10 mA, 6.40 V maximum standoff voltage (VWM), 11.3 V clamping voltage (VC) at 133 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 input stages and industrial sensor interface protection.
For engineers reviewing the 1.5KE7.5CHE3/54 datasheet, 1.5KE7.5CHE3/54 pinout, 1.5KE7.5CHE3/54 application, or 1.5KE7.5CHE3/54 equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), and direct alternative part comparisons for ESD and lightning surge protection design validation.
Technical Context
The 1.5KE7.5CHE3/54 employs a glass passivated silicon junction optimized for sub-nanosecond response (<1 ns) to transient overvoltages, enabling effective clamping before sensitive downstream components experience overstress. Its unidirectional polarity uses a cathode band marking and supports bidirectional configurations only in CA-suffix variants - not applicable to this HE3-grade part.
Rated for 1500 W peak pulse power with 10/1000 µs waveform and 0.01 % duty cycle, it delivers 133 A maximum peak pulse current (IPPM) while maintaining low incremental surge resistance and clamping ratio (VC/VBR ≈ 1.59). Thermal performance is defined by RθJL = 15.4 °C/W (junction-to-lead) and derates linearly above TA = 25 °C per Figure 2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 7.13 V to 7.88 V at 10 mA - defines minimum voltage at which TVS enters avalanche conduction to protect downstream circuitry |
| Standoff Voltage VWM | 6.40 V max - ensures no conduction during normal 5 V or 6 V rail operation, avoiding leakage-induced power loss |
| Clamping Voltage VC | 11.3 V at 133 A IPPM - limits transient voltage seen by protected ICs to safe levels under worst-case surge |
| Peak Pulse Power PPPM | 1500 W (10/1000 µs) - sustains high-energy transients such as ISO 7637-2 Pulse 1/2a/5a without failure |
| Junction Temperature Range | -55 °C to +175 °C - enables deployment in under-hood automotive and industrial environments with extreme thermal cycling |
| Thermal Resistance RθJA | 75 °C/W - determines required PCB copper area and heatsinking for continuous 6.5 W power dissipation at TL = 75 °C |
| AEC-Q101 Qualified | Yes (HE3 suffix) - validated for automotive electronics per stress test requirements including HTGB, HTRB, and temperature cycling |
Pinout & Package
1.5KE7.5CHE3/54 is housed in the standard JEDEC DO-201AD (Case Style 1.5KE) axial-leaded package with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. The cathode is marked by a color band on the body; no marking indicates bidirectional type (not applicable here).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to ground or lower-potential node in unidirectional clamp configuration |
| Cathode | Current exit point during reverse-biased clamping | Connected to protected line (e.g., 5 V rail); color band identifies this terminal |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0A | Lower PPPM (600 W), smaller SMB package (vs. DO-201AD), VBR = 7.78–8.6 V, VC = 12.0 V @ 50 A | Not AEC-Q101 qualified; limited to consumer/industrial use where space constraints dominate | Select when board space is critical and surge energy does not exceed 600 W; verify thermal margin with RθJA = 110 °C/W |
| 1.5KE7.5AHE3/54 | Same electrical specs and package, but commercial-grade (non-AEC-Q101); identical VBR, VWM, VC, PPPM | Approved for industrial/commercial use only; excluded from automotive production BOMs requiring AEC qualification | Choose for cost-sensitive non-automotive designs where full AEC-Q101 testing is unnecessary |
Compared with 1.5KE7.5CHE3/54, SMBJ7.0A trades peak power and qualification for compactness, while 1.5KE7.5AHE3/54 retains identical protection capability without automotive validation - enabling tiered sourcing based on end-equipment certification requirements.

Yes, the 1.5KE7.5CHE3/54 carries the HE3 suffix, confirming full AEC-Q101 qualification per Vishay's documentation (Document Number 88301, Revision 09-Aug-2022). This includes stress testing for high-temperature reverse bias, high-temperature operating life, and temperature cycling - making the 1.5KE7.5CHE3/54 suitable for automotive powertrain, body electronics, and ADAS applications requiring zero-failure field reliability.
What is the clamping voltage of the 1.5KE7.5CHE3/54 at its rated peak pulse current?
The 1.5KE7.5CHE3/54 clamps to a maximum of 11.3 V at its rated peak pulse current of 133 A (10/1000 µs waveform). This value is measured under standardized conditions and reflects the actual voltage imposed on protected circuitry during worst-case surge events - a critical parameter for ensuring downstream ICs like microcontrollers and LDOs remain within absolute maximum ratings when the 1.5KE7.5CHE3/54 is active.
What package type does the 1.5KE7.5CHE3/54 use, and how is polarity identified?
The 1.5KE7.5CHE3/54 uses the JEDEC DO-201AD (Case Style 1.5KE) axial-leaded package with matte tin-plated leads. Polarity is unidirectional: the cathode is identified by a distinct color band on the epoxy body, while the anode is the unmarked end. This physical marking aligns with schematic symbol orientation and ensures correct placement during manual or automated assembly of the 1.5KE7.5CHE3/54.
How does the 1.5KE7.5CHE3/54 compare to the 1.5KE7.5AHE3/54 variant?
The 1.5KE7.5CHE3/54 and 1.5KE7.5AHE3/54 share identical electrical specifications (VBR, VWM, VC, PPPM) and mechanical packaging, but differ in qualification: the "C" in 1.5KE7.5CHE3/54 denotes AEC-Q101 compliance, whereas the "A" in 1.5KE7.5AHE3/54 indicates commercial-grade only. Therefore, the 1.5KE7.5CHE3/54 is mandatory for automotive production, while the 1.5KE7.5AHE3/54 serves cost-sensitive industrial applications where AEC validation is not required.
