Product details
Overview
1.5KE75CHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power rails and signal lines. It features a 71.3 V to 78.8 V breakdown voltage (VBR) at 1 mA, 64.1 V maximum standoff voltage (VWM), 104 V clamping voltage (VC) at 14.6 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - used to safeguard MOSFETs, ICs, and sensor interfaces in industrial power supplies and automotive ECUs.
For engineers reviewing the 1.5KE75CHE3/54 datasheet, 1.5KE75CHE3/54 pinout, 1.5KE75CHE3/54 application, or 1.5KE75CHE3/54 equivalent, this page delivers verified electrical parameters, JEDEC-standard 1.5KE package details, AEC-Q101 qualification status, thermal resistance data, and real-world protection use cases - all confirmed from Vishay's official 88301 document revision 09-Aug-2022.
Technical Context
This TVS diode operates as a unidirectional clamping device with glass-passivated junction construction, enabling sub-nanosecond response time (<1 ns) and low incremental surge resistance. Its 1500 W peak pulse power handling is specified under 10/1000 µs waveform at 0.01% duty cycle, with derating above 25 °C per Fig. 2 of the datasheet.
Thermal performance is defined by RθJA = 75 °C/W (junction-to-ambient) and RθJL = 15.4 °C/W (junction-to-lead), supporting reliable operation up to TJ = 175 °C. The device meets JESD 22-B106 solder dip requirements (275 °C max, 10 s) and JESD 201 Class 1A whisker testing (E3 suffix).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 71.3 V / 78.8 V at IT = 1 mA - defines precise voltage threshold where clamping initiates under transient stress |
| VWM | 64.1 V maximum - ensures no conduction during normal 64 V system operation, preventing leakage-induced power loss |
| VC @ IPPM | 104 V at 14.6 A - limits downstream voltage excursion to safe levels for 3.3 V/5 V logic and 60 V-rated MOSFETs |
| PPPM | 1500 W - sustains single 10/1000 µs surges common in ISO 7637-2 automotive load dump and IEC 61000-4-5 surge events |
| IFSM | 200 A (8.3 ms half-sine) - withstands high-energy inrush or fault currents without bond wire fusing |
| TJ range | –55 °C to +175 °C - supports deployment in under-hood automotive, industrial motor drives, and outdoor power electronics |
| Package | JEDEC DO-201AD (Case Style 1.5KE) - industry-standard axial leaded package with 0.375" lead length, UL 94 V-0 molding |
Pinout & Package
1.5KE75CHE3/54 uses the standard DO-201AD axial package (Case Style 1.5KE), with cathode indicated by a color band on one end. Leads are matte tin-plated and solderable per J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to ground or low-side reference; enables unidirectional clamping from VCC to GND |
| Cathode | Current exit point during forward conduction; marked with band | Connected to protected line (e.g., 48 V rail); conducts only when Vin exceeds VBR, shunting surge to GND |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling and humidity exposure |
| 1500 W peak pulse power (10/1000 µs) | Provides single-event surge immunity exceeding IEC 61000-4-5 Level 4 (4 kV line-earth) without derating |
| AEC-Q101 qualified (HE3 variant) | Validated for automotive applications including engine control units, body electronics, and ADAS power domains |
| Low incremental surge resistance | Minimizes VC – VBR differential, reducing clamping overshoot and protecting sensitive gate oxides |
| UL 94 V-0 compliant epoxy case | Meets flammability safety requirements for enclosed industrial and transportation equipment enclosures |
Applications
| Automotive Power Rail Protection | Industrial DC Power Input |
|---|---|
Use Scenario: Protecting 48 V battery-fed ECU power inputs against load dump transients per ISO 7637-2 Pulse 5a. IC Role / Device Role / Timing Role: Unidirectional TVS placed between VBAT and chassis ground to clamp surges up to 120 V within <1 ns. Use Value: Limits voltage seen by downstream DC/DC controllers and microcontrollers to ≤104 V, preventing latch-up or oxide rupture. |
Use Scenario: Safeguarding 24 V PLC input modules exposed to inductive switching noise from solenoids and contactors. IC Role / Device Role / Timing Role: Standoff-rated TVS on field-side terminals, conducting only during >64.1 V transients. Use Value: Eliminates need for RC snubbers or varistors, reducing BOM count while maintaining 1500 W surge margin. |
| MOSFET Gate Protection | Sensor Signal Line Clamping |
Use Scenario: Shielding N-channel high-side MOSFET gates driven by isolated gate drivers in motor inverters. IC Role / Device Role / Timing Role: Low-capacitance TVS across gate-source to suppress Miller-induced dv/dt spikes. Use Value: Prevents false turn-on and gate oxide breakdown with 104 V clamping and sub-ns response. |
Use Scenario: Protecting analog outputs of pressure/temperature sensors connected to long harnesses in factory automation. IC Role / Device Role / Timing Role: Bidirectional-capable variant (1.5KE75CA) used on differential pairs; unidirectional version applied to single-ended lines. Use Value: Maintains signal integrity below 64.1 V while clamping lightning-induced surges to ≤104 V. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ75A-E3/52 | DO-214AA (SMB) package; 75 V VBR min, 100 V VC @ 12.5 A; 600 W PPPM | Lower power rating suits space-constrained PCBs but requires parallel devices for 1500 W compliance | Select when board area is limited and surge energy is ≤600 W; verify thermal layout for SMB footprint |
| 1.5KE75A-E3/54 | Same 1.5KE package and VBR/VC specs, but lacks AEC-Q101 qualification and HE3 whisker rating | Approved for commercial/industrial use only; not certified for automotive production environments | Choose for cost-sensitive non-automotive designs where AEC-Q101 is not mandated |
Compared with 1.5KE75CHE3/54, SMBJ75A-E3/52 offers smaller footprint but reduced surge capacity, while 1.5KE75A-E3/54 matches mechanical and electrical specs but omits automotive qualification - making 1.5KE75CHE3/54 the sole option when AEC-Q101 compliance and Class 1A whisker resistance are mandatory.

FAQ
What is the exact breakdown voltage range for 1.5KE75CHE3/54?
The 1.5KE75CHE3/54 has a guaranteed breakdown voltage (VBR) range of 71.3 V to 78.8 V at test current IT = 1 mA, per Vishay Document Number 88301, Table on page 2. This range ensures consistent clamping initiation across production lots and temperature extremes from –55 °C to +175 °C.
Is 1.5KE75CHE3/54 AEC-Q101 qualified?
Yes, 1.5KE75CHE3/54 is AEC-Q101 qualified, as confirmed in the "RATINGS AND CHARACTERISTICS CURVES" section (page 3) of Vishay's 88301 datasheet, which states qualification applies to "1.5KE6.8AHE3_B to 1.5KE220AHE3_B". The HE3 suffix and "B" revision code denote this qualification level.
What does the "HE3/54" suffix mean in 1.5KE75CHE3/54?
In 1.5KE75CHE3/54, "HE3" indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; "54" denotes the preferred package code for 13-inch paper tape and reel packaging with 1400 units per reel, per the Ordering Information table on page 3 of the datasheet.
How does 1.5KE75CHE3/54 differ from 1.5KE75A-E3/54?
The 1.5KE75CHE3/54 includes AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas 1.5KE75A-E3/54 carries only commercial-grade certification and Class 1A whisker rating. Both share identical electrical specs and DO-201AD packaging, but only the HE3 variant is approved for automotive production use.
What is the clamping voltage of 1.5KE75CHE3/54 at its rated peak pulse current?
The 1.5KE75CHE3/54 clamps to a maximum of 104 V at its rated peak pulse current (IPPM) of 14.6 A, measured under the standardized 10/1000 µs waveform. This value is specified in the Electrical Characteristics table (page 2) and defines the upper voltage limit imposed on protected circuitry during surge events.
