Product details
Overview
1.5KE200CAHE3_B/C from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode designed for high-energy surge protection in power and signal lines. It features a 200 V breakdown voltage (VBR = 209–231 V), 1500 W peak pulse power (10/1000 µs), clamping voltage of 328 V at 4.6 A, and operates across –55 °C to +175 °C. It is used to protect MOSFETs, ICs, and sensor interfaces against lightning-induced transients and inductive switching spikes in automotive and industrial systems.
For engineers reviewing the 1.5KE200CAHE3_B/C datasheet, 1.5KE200CAHE3_B/C pinout, 1.5KE200CAHE3_B/C application, or 1.5KE200CAHE3_B/C equivalent, this page delivers verified electrical specs, JEDEC 1.5KE package details, bidirectional clamping behavior, AEC-Q101 qualification status, and real-world use cases - all confirmed from Vishay's official 88301 document and ordering data.
Technical Context
This device implements a glass-passivated silicon junction optimized for fast transient response (<1 ns) and low incremental surge resistance. Its bidirectional architecture enables symmetrical clamping in both polarities without polarity marking, supporting AC-coupled or floating-line protection schemes.
Rated for 1500 W peak pulse power under 10/1000 µs waveform with 0.01% duty cycle, it derates linearly above 25 °C ambient per Fig. 2 and maintains stable clamping up to TJ = 175 °C. The HE3 suffix confirms RoHS compliance and AEC-Q101 qualification per note (2) in the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 209 V / 231 V - ensures reliable conduction onset above normal operating voltage while avoiding false triggering |
| VWM | 185 V - maximum continuous reverse standoff voltage compatible with 170–180 V DC bus or AC peak applications |
| VC @ IPPM | 328 V - clamping voltage at 4.6 A peak pulse current, limiting downstream voltage stress during surge events |
| PPPM | 1500 W - handles high-energy transients such as lightning surges (IEC 61000-4-5 Level 4) on power rails |
| IPPM | 4.6 A - peak pulse current capacity under standardized 10/1000 µs waveform |
| TJ range | –55 °C to +175 °C - supports under-hood automotive and industrial environments without derating loss |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200CA | 600 W PPPM, DO-214AA package, lower IPPM (32.4 A), same VBR range | Lower energy handling; suited for PCB space-constrained designs where 1500 W is not required | Select when board area is limited and surge threat level is Class 3 (IEC 61000-4-5) or below |
| 1.5SMC200CA | Same 1500 W rating, SMC (DO-214AB) package, higher thermal resistance (RθJA = 110 °C/W vs. 75 °C/W) | Less efficient heat dissipation; requires larger copper area for equivalent thermal performance | Choose only if existing layout uses SMC footprint and AEC-Q101 qualification is not mandatory |
Compared with SMBJ200CA and 1.5SMC200CA, the 1.5KE200CAHE3_B/C delivers superior thermal performance (RθJL = 15.4 °C/W), AEC-Q101 qualification, and proven ruggedness in high-reliability automotive and industrial deployments - making it the preferred choice where sustained surge immunity and long-term stability are critical.

Yes, the 1.5KE200CAHE3_B/C is AEC-Q101 qualified, as confirmed in Note (2) of the Vishay 88301 datasheet. The "HE3" suffix explicitly denotes RoHS compliance and AEC-Q101 qualification for the 1.5KE6.8CAHE3_B to 1.5KE220CAHE3_B family, including this part. This validation covers HTGB, HTRB, and temperature cycling tests required for automotive under-hood use.
What is the clamping voltage of the 1.5KE200CAHE3_B/C at its rated peak pulse current?
The 1.5KE200CAHE3_B/C clamps to a maximum of 328 V at its peak pulse current (IPPM) of 4.6 A under the standard 10/1000 µs waveform. This value is measured per Figure 9 and Table on page 2 of the Vishay 88301 datasheet and defines the upper voltage limit imposed on protected circuitry during surge events.
Does the 1.5KE200CAHE3_B/C have polarity markings?
No, the 1.5KE200CAHE3_B/C does not have polarity markings because it is a bidirectional TVS diode. As stated in the datasheet: "no marking on bidirectional types." Its symmetrical construction allows installation in either orientation across AC lines or ungrounded signal paths without functional impact.
What package type does the 1.5KE200CAHE3_B/C use?
