Product details
Overview
1.5KE200A-E3/54 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 standoff voltage (VWM), 210 V maximum breakdown voltage (VBR), 274 V clamping voltage at 5.5 A peak pulse current, 1500 W peak pulse power rating (10/1000 µs), and operates across –55 °C to +175 °C junction temperature range.
For engineers reviewing the 1.5KE200A-E3/54 datasheet, 1.5KE200A-E3/54 pinout, 1.5KE200A-E3/54 application, or 1.5KE200A-E3/54 equivalent, this device serves as a robust, glass-passivated, RoHS-compliant surge protector for automotive power supplies, industrial sensor interfaces, and telecom line cards where fast clamping (<1 ns), low incremental surge resistance, and AEC-Q101-qualified reliability are required.
Technical Context
The 1.5KE200A-E3/54 implements a silicon avalanche junction structure optimized for transient suppression in unidirectional configurations. Its clamping behavior follows standardized 10/1000 µs waveform testing per IEC 61000-4-5, with thermal resistance of 15.4 °C/W (junction-to-lead) enabling effective heat dissipation during repetitive surges.
It delivers 5.5 A peak pulse current (IPPM) at 274 V clamping voltage (VC), with 1.0 mA test current (IT) defining VBR, and exhibits 1.0 µA max reverse leakage at 171 V (VWM). The device uses a molded epoxy case meeting UL 94 V-0 and matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200A | Lower PPPM (600 W), smaller SMB package (surface-mount), 274 V VC same | Preferred for space-constrained PCBs; not suitable for high-energy 1500 W surges | Select when board area is limited and surge energy is ≤600 W |
| 1.5KE200CA | Bidirectional version; identical VBR/VC/PPPM but symmetrical clamping in both polarities | Required for AC-coupled or floating signal lines where polarity reversal occurs | Choose only if bidirectional protection is needed; 1.5KE200A-E3/54 is unidirectional-only |
Compared with SMBJ200A and 1.5KE200CA, the 1.5KE200A-E3/54 uniquely combines 1500 W surge capacity with axial-leaded through-hole mounting and commercial-grade reliability-making it optimal for high-energy, serviceable, or legacy-compatible designs where PCB real estate and polarity constraints permit.

FAQ
What is the clamping voltage of the 1.5KE200A-E3/54 under standard surge conditions?
The 1.5KE200A-E3/54 has a maximum clamping voltage (VC) of 274 V when subjected to its rated peak pulse current (IPPM) of 5.5 A using the industry-standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and ensures predictable overvoltage limiting for downstream components such as DC-DC controllers or microcontroller power inputs.
Is the 1.5KE200A-E3/54 RoHS compliant and qualified for automotive use?
The 1.5KE200A-E3/54 carries the E3 suffix, confirming RoHS compliance and JESD 201 Class 1A whisker resistance. However, it is a commercial-grade part (not AEC-Q101 qualified); for automotive applications, engineers must select the HE3 variant (e.g., 1.5KE200AHE3_B), which is explicitly qualified per AEC-Q101.
How does the 1.5KE200A-E3/54 differ from bidirectional TVS diodes like 1.5KE200CA?
The 1.5KE200A-E3/54 is unidirectional and functions only in reverse-bias mode-clamping positive transients on the cathode side. In contrast, 1.5KE200CA provides symmetrical clamping for both polarities, making it suitable for AC signals or floating nodes. Their VBR, VC, and PPPM ratings are identical, but polarity behavior and circuit placement differ fundamentally.
What is the maximum operating temperature range for the 1.5KE200A-E3/54?
The 1.5KE200A-E3/54 supports an operating junction and storage temperature range of –55 °C to +175 °C. This wide range enables deployment in under-hood automotive modules, industrial motor drives, and outdoor telecom equipment without thermal derating penalties up to 175 °C junction temperature.
Can the 1.5KE200A-E3/54 be used in parallel to increase surge handling capacity?
Yes-the 1.5KE200A-E3/54 may be paralleled to increase total peak pulse power handling, provided matched units are used and layout minimizes inductance imbalance. However, due to minor VBR tolerances (190–210 V), current sharing is not perfectly balanced; derating by ≥20 % is recommended for multi-device configurations.
