Product details
Overview
1.5KE200HE3/54 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 200 V breakdown voltage (VBR = 190–210 V), 171 V maximum working voltage (VWM), 274 V clamping voltage at 5.5 A peak pulse current, 1500 W peak pulse power (10/1000 µs), and operates across –55 °C to +175 °C junction temperature. It is used in automotive power supply inputs and industrial sensor interface protection.
For engineers reviewing the 1.5KE200HE3/54 datasheet, 1.5KE200HE3/54 pinout, 1.5KE200HE3/54 application, or 1.5KE200HE3/54 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJL = 15.4 °C/W), RoHS-compliant matte tin plating, and JEDEC 1.5KE package mechanical data - all confirmed from Vishay's official 88301 datasheet revision 09-Aug-2022.
Technical Context
This TVS diode employs a glass-passivated silicon junction optimized for fast transient response (<1 ns) and low incremental surge resistance. Its unidirectional polarity uses a cathode band marking and supports 200 A non-repetitive forward surge current (IFSM) with 3.5 V max forward voltage at 100 A.
The device complies with UL 497B (QVGQ2 recognition), meets JESD 201 Class 2 whisker resistance (HE3 suffix), and is rated for 10 s solder dip at 275 °C per JESD 22-B106 - confirming suitability for lead-free reflow and high-reliability automotive PCB assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 190 V / 210 V - ensures reliable conduction onset above normal operating voltage while avoiding false triggering |
| VWM | 171 V - maximum continuous reverse voltage the device blocks without leakage exceeding 1 μA |
| VC @ IPPM | 274 V - clamping voltage during 5.5 A 10/1000 µs transient, limiting downstream component stress |
| PPPM | 1500 W - peak pulse power handling capability for lightning or inductive-switching transients |
| IFSM | 200 A - surge current rating for 8.3 ms half-sine waveform, supporting high-energy fault events |

Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECU power input against load dump (ISO 16750-2) and alternator transients. IC Role / Device Role / Timing Role: Primary shunt clamp placed between battery rail and ground, conducting transients before upstream regulators or MCUs are stressed. Use Value: Clamps 12 V system transients up to 274 V at 5.5 A, preserving 1500 W surge margin and enabling compliance with ISO 7637-2 Level 5a. | Use Scenario: Safeguarding analog outputs of pressure/temperature sensors connected to PLC I/O modules. IC Role / Device Role / Timing Role: Unidirectional TVS placed on sensor output line to ground, suppressing ESD and inductive kickback from nearby solenoids. Use Value: Sub-1 ns response time limits voltage overshoot to ≤274 V, preventing damage to 24 V-tolerant ADC inputs and maintaining signal integrity. |
| Telecom DC Power Feeds | Consumer Appliance Motor Drive Inputs |
Use Scenario: Overvoltage protection on -48 V telecom rectifier outputs exposed to lightning-induced surges on outdoor lines. IC Role / Device Role / Timing Role: Standoff-rated TVS (VWM = 171 V) installed at power entry point to absorb common-mode transients before DC/DC converters. Use Value: Withstands repetitive 1500 W pulses at 0.01% duty cycle, meeting Telcordia GR-1089-CORE surge immunity requirements. | Use Scenario: Input-stage protection for BLDC motor drivers in washing machines subjected to relay contact bounce and transformer coupling. IC Role / Device Role / Timing Role: Unidirectional suppressor mounted across bridge rectifier output to clamp switching spikes before bulk capacitor and gate drivers. Use Value: 200 A IFSM rating handles repeated inrush and commutation surges; 175 °C TJmax supports sealed enclosure operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200A-E3/52 | Lower PPPM (600 W), smaller SMB package (vs. 1.5KE), VC = 324 V @ 1.9 A | Not suitable for 1500 W lightning-level transients; limited to board-level ESD or low-energy switching noise | Select only if space-constrained and surge energy is <600 W; verify layout thermal relief for SMB footprint |
| 1.5KE200A-E3/54 | Same electrical specs but commercial-grade (non-AEC-Q101), no JESD 201 Class 2 whisker test | Lacks automotive qualification; not approved for under-hood or safety-critical modules | Acceptable for industrial/commercial power supplies where AEC-Q101 is not mandated |
Compared with 1.5KE200HE3/54, SMBJ200A-E3/52 trades surge robustness for compactness, while 1.5KE200A-E3/54 retains identical clamping performance but omits automotive reliability validation - making the HE3/54 version essential for Tier-1 automotive designs requiring traceable qualification evidence.

FAQ
What is the clamping voltage of the 1.5KE200HE3/54 at its rated peak pulse current?
The 1.5KE200HE3/54 has a maximum clamping voltage (VC) of 274 V at its specified peak pulse current (IPPM) of 5.5 A, measured using the standard 10/1000 µs double-exponential waveform. This value is guaranteed per Vishay Document Number 88301 and defines the upper voltage limit imposed on protected circuits during transient events. The 1.5KE200HE3/54 maintains this clamping performance across its full operating temperature range.
Is the 1.5KE200HE3/54 qualified for automotive applications?
Yes, the 1.5KE200HE3/54 is AEC-Q101 qualified, as confirmed by Vishay's datasheet revision 09-Aug-2022 (Document Number 88301), footnote (2) under "RATINGS AND CHARACTERISTICS CURVES". The HE3 suffix explicitly denotes AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. This makes the 1.5KE200HE3/54 suitable for automotive powertrain, chassis, and body electronics where certified reliability is mandatory.
What does the "HE3/54" suffix mean in 1.5KE200HE3/54?
The "HE3" suffix indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; "/54" specifies the preferred packaging option: 13-inch paper tape and reel containing 1400 units. This ordering code aligns with Vishay's standardized delivery format for high-volume automotive and industrial procurement. The 1.5KE200HE3/54 is not interchangeable with non-HE3 variants due to its qualified reliability status.
Can the 1.5KE200HE3/54 be used in bidirectional configurations?
No, the 1.5KE200HE3/54 is a unidirectional TVS diode. Bidirectional versions use the "CA" suffix (e.g., 1.5KE200CA), and Vishay explicitly states that bidirectional types are available only up to 1.5KE220CA. The 1.5KE200HE3/54 has a cathode band marking and is intended for DC rail protection where polarity is fixed; using it in AC or floating applications would result in forward conduction during one half-cycle.
What is the thermal resistance from junction to lead (RθJL) for the 1.5KE200HE3/54?
The 1.5KE200HE3/54 has a typical junction-to-lead thermal resistance (RθJL) of 15.4 °C/W, as published in the "THERMAL CHARACTERISTICS" table of Vishay Document Number 88301. This low value enables efficient heat transfer from the silicon die to the PCB copper through the leads, supporting sustained power dissipation without external heatsinking - critical for compact automotive and industrial layouts where airflow is limited.
