Product details
Overview
1.5KE200HE3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in 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 to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies and automotive ECUs.
For engineers reviewing the 1.5KE200HE3/73 datasheet, 1.5KE200HE3/73 pinout, 1.5KE200HE3/73 application, or 1.5KE200HE3/73 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJL = 15.4 °C/W), JEDEC 1.5KE package dimensions, and real-world clamping behavior under lightning-surge transients per IEC 61000-4-5.
Technical Context
This unidirectional TVS diode uses a glass-passivated silicon junction to achieve sub-nanosecond response time (<1 ns) and low incremental surge resistance. Its clamping action initiates at VBR = 190–210 V with 1 mA test current and limits transient energy to ≤274 V at 5.5 A (10/1000 µs waveform), enabling robust protection of downstream 200 V-rated components.
Rated for 1500 W peak pulse power and 6.5 W steady-state dissipation on infinite heatsink, it supports repetitive surge events at ≤0.01% duty cycle. The HE3 suffix confirms RoHS compliance and AEC-Q101 qualification-valid for 1.5KE6.8AHE3_B through 1.5KE220AHE3_B variants only; 1.5KE200HE3/73 falls within this qualified range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 190 V / 210 V - Ensures reliable triggering above system nominal voltage while avoiding false trips during normal operation. |
| VWM | 171 V - Maximum continuous reverse standoff voltage; defines upper limit of safe DC operating range. |
| VC @ IPPM | 274 V - Clamped voltage at 5.5 A peak pulse; determines worst-case stress imposed on protected circuitry. |
| PPPM | 1500 W - Peak pulse power handling (10/1000 µs); enables suppression of high-energy lightning-induced surges. |
| IPPM | 5.5 A - Peak pulse current capacity; directly correlates with surge immunity level per IEC 61000-4-5 Level 4. |
| TJ max. | +175 °C - High junction temperature rating supports under-hood automotive and industrial environments. |
| RθJL | 15.4 °C/W - Low junction-to-lead thermal resistance allows efficient heat transfer to PCB copper or heatsink. |

| Low RθJL (15.4 °C/W) | Permits direct mounting to copper pour for thermal management without external heatsink in most PCB designs. |
Applications
| Automotive Power Rail Protection | Industrial PLC Input Protection |
|---|---|
Use Scenario: Protecting 24 V supply inputs in engine control modules against load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional TVS placed between VIN and chassis ground to clamp transients >171 V before reaching DC/DC converters.

Use Scenario: Preventing gate oxide rupture in high-side N-channel MOSFET drivers subjected to inductive kickback. IC Role / Device Role / Timing Role: Connected cathode-to-drain, anode-to-source to clamp VDS spikes during turn-off of inductive loads. Use Value: Limits VDS overshoot to 274 V, ensuring safe operation below 300 V rated MOSFETs without snubber networks. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200A | Lower PPPM (600 W), smaller SMB package (vs. axial 1.5KE), higher VC (324 V @ 1.85 A) | Not AEC-Q101 qualified; suited for space-constrained consumer electronics, not automotive under-hood use. | Select when board area is critical and surge levels are ≤2 kV; avoid where 1500 W headroom or automotive qualification is required. |
| 1.5KE200A-E3/54 | Same electrical specs and 1.5KE package, but commercial-grade (non-AEC-Q101) and packaged in tape-and-reel (54) vs. bulk (73) | Lacks automotive qualification; suitable for industrial controls or telecom where AEC-Q101 is not mandated. | Choose for cost-sensitive non-automotive designs requiring identical performance and form factor without qualification overhead. |
Compared with SMBJ200A and 1.5KE200A-E3/54, the 1.5KE200HE3/73 uniquely combines AEC-Q101 qualification, 1500 W pulse rating, and axial leaded packaging-making it the only option among the three validated for automotive power rail protection with full traceability and extended temperature support.

FAQ
What is the clamping voltage of the 1.5KE200HE3/73 under a 10/1000 µs surge?
The 1.5KE200HE3/73 clamps to a maximum of 274 V at its rated peak pulse current of 5.5 A using the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during surge events. It is derived directly from the device's silicon junction characteristics and is guaranteed across the full operating temperature range.
Is the 1.5KE200HE3/73 AEC-Q101 qualified?
Yes, the 1.5KE200HE3/73 is AEC-Q101 qualified. Per Vishay documentation (Document Number 88301, Revision 09-Aug-2022), the HE3 suffix denotes RoHS compliance and AEC-Q101 qualification for the 1.5KE6.8AHE3_B through 1.5KE220AHE3_B family-including 1.5KE200HE3/73. Qualification covers temperature cycling, mechanical shock, and high-temperature operating life testing per automotive standards.
What does the "HE3/73" suffix mean in 1.5KE200HE3/73?
The "HE3" suffix indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. The "/73" denotes bulk packaging in ammo pack format (as opposed to tape-and-reel "/54" or "/C"). This packaging variant is intended for manual assembly, prototyping, or low-volume production where reel feeding is unnecessary.
Can the 1.5KE200HE3/73 be used in bidirectional configurations?
No, the 1.5KE200HE3/73 is a unidirectional TVS diode. Bidirectional variants in the same family use the "CA" suffix (e.g., 1.5KE200CA). The 1.5KE200HE3/73 has a cathode band marking and conducts only in reverse bias-making it unsuitable for AC line or differential signal protection without external circuitry. Use 1.5KE200CAHE3/73 for true bidirectional clamping.
What is the thermal resistance from junction to lead (RθJL) for the 1.5KE200HE3/73?
The 1.5KE200HE3/73 has a typical junction-to-lead thermal resistance (RθJL) of 15.4 °C/W, as specified in Vishay's thermal characteristics table. This value reflects heat conduction efficiency from the silicon die to the device's leads and is critical for estimating temperature rise during repetitive surge events or elevated ambient conditions-especially in automotive under-hood applications.
