Product details
Overview
1.5KE180CHE3/54 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 180 V breakdown voltage (VBR = 171–189 V at 1 mA), 154 V maximum working voltage (VWM), 246 V clamping voltage (VC) at 6.1 A peak pulse current, 1500 W peak pulse power (10/1000 µs), and operates across –55 °C to +175 °C junction temperature. It protects MOSFETs and ICs in industrial power supplies.
For engineers reviewing the 1.5KE180CHE3/54 datasheet, 1.5KE180CHE3/54 pinout, 1.5KE180CHE3/54 application, or 1.5KE180CHE3/54 equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, AEC-Q101 qualification status, thermal resistance (RθJL = 15.4 °C/W), and real-world clamping behavior under transient stress.
Technical Context
This TVS diode uses a glass-passivated silicon junction optimized for fast response (<1 ns) and low incremental surge resistance. Its unidirectional polarity enables cathode-grounded placement on positive supply rails, with a 3.5 V forward voltage (VF) at 100 A - consistent with devices ≤1.5KE220A per specification note (3).
The device complies with UL 497B (QVGQ2 recognition) and meets JESD 201 Class 2 whisker resistance (HE3 suffix). It is rated for 200 A non-repetitive forward surge (8.3 ms half-sine) and derates linearly above 25 °C ambient per Figure 2, supporting robust operation in automotive and industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 171 V / 189 V at 1 mA - defines precise clamping onset threshold for overvoltage detection |
| VWM | 154 V - maximum continuous DC or RMS voltage the device blocks without leakage exceeding 1 μA |
| VC @ IPPM | 246 V at 6.1 A - clamped voltage during 10/1000 µs surge, limiting downstream component stress |
| PPPM | 1500 W - peak transient power handling capability, enabling protection against lightning-induced surges |
| IFSM | 200 A - withstands 8.3 ms half-sine surge, critical for motor drive and relay-switching transients |
| TJ max | +175 °C - supports operation in under-hood automotive and high-temperature industrial enclosures |
| RθJL | 15.4 °C/W - low junction-to-lead thermal resistance enables effective heat dissipation through PCB copper |
Pinout & Package
Package: JEDEC DO-201AD (Case Style 1.5KE), molded epoxy body with matte tin-plated leads; RoHS-compliant and AEC-Q101 qualified (HE3 suffix); lead length 0.375" (9.5 mm).

Applications
| Industrial Power Supply Protection | Automotive ECUs |
|---|---|
Use Scenario: 24 V DC input stage of programmable logic controller (PLC) exposed to load dump and inductive switching transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between +24 V rail and chassis ground to clamp transients before they reach DC-DC converters and microcontrollers. Use Value: Clamps 10/1000 µs surges to ≤246 V, preventing damage to 36 V-rated input capacitors and 5 V LDOs downstream. |
Use Scenario: CAN bus power line in engine control unit subjected to ISO 7637-2 Pulse 5a (load dump up to 60 V). IC Role / Device Role / Timing Role: Primary overvoltage clamp on 12 V supply feeding CAN transceivers and MCU core logic. Use Value: Withstands 200 A surge (8.3 ms) and maintains VC ≤246 V, preserving CAN signal integrity and avoiding brownout resets. |
| Telecom Line Interface | Motor Drive Control Board |
Use Scenario: -48 V DC feed line in remote radio head (RRH) exposed to lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: Cathode-to-ground configuration on negative supply rail to suppress positive-going transients relative to system ground. Use Value: UL 497B recognition ensures compliance with telecom safety standards; 175 °C TJ max supports sealed enclosure operation. |
Use Scenario: Gate driver supply rail in 3-phase inverter where IGBT turn-off induces dV/dt spikes on low-side driver VCC. IC Role / Device Role / Timing Role: Local TVS across gate driver VCC-GND to suppress sub-100 ns ringing and prevent false triggering. Use Value: <1 ns response time limits voltage overshoot to <250 V, protecting 20 V-rated gate drivers without adding capacitance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ180A | Lower PPPM (600 W), smaller SMB package (vs. DO-201AD), higher VC (292 V @ 2.1 A) | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 or automotive load dump | Select only when board space is constrained and surge energy is ≤600 W; verify layout thermal relief for SMB footprint. |
| 1.5KE180A-E3/54 | Same electrical specs but commercial-grade (non-AEC-Q101); identical DO-201AD package and pinout | Not qualified for automotive under-hood use; acceptable for industrial/commercial power supplies | Choose for cost-sensitive non-automotive designs where AEC-Q101 is not mandated; same PCB layout and solder profile. |
Compared with 1.5KE180CHE3/54, SMBJ180A trades peak power and thermal robustness for compactness, while 1.5KE180A-E3/54 offers identical protection performance without automotive qualification - enabling direct substitution where AEC-Q101 is unnecessary.

FAQ
What is the clamping voltage of the 1.5KE180CHE3/54 under a standard 10/1000 µs surge?
The 1.5KE180CHE3/54 clamps to a maximum of 246 V at its rated peak pulse current of 6.1 A (10/1000 µs waveform). This value is measured per Figure 7 in the Vishay datasheet 88301 and reflects worst-case incremental clamping behavior under standardized surge conditions. The 1.5KE180CHE3/54 maintains this performance across its full operating temperature range.
Is the 1.5KE180CHE3/54 suitable for automotive applications?
Yes - the HE3 suffix confirms AEC-Q101 qualification per notes (1) and (2) in the Vishay datasheet 88301, covering devices from 1.5KE6.8AHE3_B to 1.5KE220AHE3_B. The 1.5KE180CHE3/54 is validated for automotive powertrain and body electronics, including load dump and ISO 7637-2 pulse immunity testing. Its 175 °C maximum junction temperature further supports under-hood deployment.
How does the 1.5KE180CHE3/54 differ from the commercial-grade 1.5KE180A-E3/54?
The 1.5KE180CHE3/54 adds AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, while maintaining identical electrical specifications (VBR, VWM, VC, PPPM) and DO-201AD package as the commercial 1.5KE180A-E3/54. Both share the same thermal resistance (RθJL = 15.4 °C/W) and UL 497B recognition. The 1.5KE180CHE3/54 is required for automotive use; the A-E3/54 suffices for industrial/commercial designs.
What is the maximum reverse leakage current for the 1.5KE180CHE3/54 at its working voltage?
At its maximum stand-off voltage of 154 V (VWM), the 1.5KE180CHE3/54 exhibits a maximum reverse leakage current (ID) of 1.0 μA, as specified in the Electrical Characteristics table (row for 1.5KE180A). This low leakage ensures minimal power loss in standby and prevents false triggering in high-impedance sensing circuits powered by the protected rail.
Can the 1.5KE180CHE3/54 be used in bidirectional configurations?
No - the "A" suffix in 1.5KE180CHE3/54 denotes unidirectional polarity. Bidirectional variants use the "CA" suffix (e.g., 1.5KE180CA), and the datasheet explicitly states bidirectional types are available only from 1.5KE6.8CA to 1.5KE220CA. Using the 1.5KE180CHE3/54 in bidirectional applications would result in forward conduction during negative transients, causing failure.
