Product details
Overview
1.5KE200CHE3/54 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 200 V breakdown voltage (VBR = 190–210 V at IT = 1 mA), 1500 W peak pulse power (10/1000 µs), clamping voltage of 274 V at 5.5 A, 6.5 W steady-state power dissipation, and operates from –55 °C to +175 °C. It is used to protect MOSFETs, ICs, and sensor interfaces against lightning-induced transients and inductive switching spikes.
For engineers reviewing the 1.5KE200CHE3/54 datasheet, 1.5KE200CHE3/54 pinout, 1.5KE200CHE3/54 application, or 1.5KE200CHE3/54 equivalent, this part delivers verified clamping performance, AEC-Q101 qualification (HE3 suffix), RoHS-compliant matte tin leads, and JEDEC-standard 1.5KE case packaging - critical for automotive power supply protection, industrial motor drive I/O, and telecom line interface design.
Technical Context
This unidirectional TVS diode uses a glass-passivated silicon junction optimized for fast response (<1 ns) and low incremental surge resistance. Its clamping behavior is defined by a well-characterized VC–IPPM curve with 274 V maximum clamping at 5.5 A IPPM under 10/1000 µs waveform, and it maintains stable thermal performance with RθJL = 15.4 °C/W and RθJA = 75 °C/W.
The device supports repetitive surge events at ≤0.01% duty cycle and complies with JESD 22-B106 (275 °C solder dip, 10 s). Its 1.5KE package enables through-hole mounting with 0.375" lead length, and the HE3 suffix confirms AEC-Q101 qualification per revision B - validated for automotive engine control units and battery management systems.

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-E3/52 | Surface-mount SMB package; same VBR (190–210 V), but lower PPPM = 600 W and higher VC = 324 V at 1.85 A | Designed for PCB space-constrained designs; lacks AEC-Q101 qualification in base E3 version | Select when board area is limited and surge energy is ≤600 W; verify thermal relief for sustained power dissipation |
| 1.5KE200AHE3_B | Identical electrical specs and AEC-Q101 qualification; differs only in packaging - bulk vs. tape-and-reel (54) delivery | No functional difference; same use cases and layout compatibility | Choose 1.5KE200AHE3_B for manual prototyping or low-volume builds; 1.5KE200CHE3/54 preferred for automated SMT line feeding |
Compared with SMBJ200A-E3/52, 1.5KE200CHE3/54 offers 2.5× higher surge power handling and lower clamping voltage, making it suitable for harsher environments; versus 1.5KE200AHE3_B, it provides identical protection performance with optimized reel packaging for high-throughput manufacturing.

FAQ
What is the breakdown voltage tolerance for 1.5KE200CHE3/54?
The 1.5KE200CHE3/54 has a specified breakdown voltage range of 190 V to 210 V at 1 mA test current, representing a ±5% tolerance around the nominal 200 V rating. This tight VBR window ensures predictable clamping onset and compatibility with system-level overvoltage thresholds defined in automotive and industrial standards such as ISO 7637-2.
Is 1.5KE200CHE3/54 suitable for bidirectional transient protection?
No, 1.5KE200CHE3/54 is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. For bidirectional protection, Vishay offers the 1.5KE200CA variant. Using 1.5KE200CHE3/54 in AC or floating applications would require external circuitry (e.g., back-to-back configuration), whereas 1.5KE200CHE3/54 is optimized for DC rail clamping where polarity is fixed.
Does 1.5KE200CHE3/54 meet AEC-Q101 requirements?
Yes, the "HE3" suffix in 1.5KE200CHE3/54 explicitly denotes AEC-Q101 qualification per revision B, covering stress tests including HTGB, HTRB, TCT, and ESD. This makes 1.5KE200CHE3/54 appropriate for automotive powertrain, body electronics, and ADAS subsystems where component reliability under thermal and electrical stress is mandated.
What is the maximum clamping voltage of 1.5KE200CHE3/54 under surge conditions?
The maximum clamping voltage (VC) of 1.5KE200CHE3/54 is 274 V at 5.5 A peak pulse current (IPPM) 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 worst-case transient events - critical for ensuring downstream ICs remain within absolute maximum ratings.
How does the 1.5KE200CHE3/54 package differ from SMBJ or SMC variants?
The 1.5KE200CHE3/54 uses the axial-leaded 1.5KE case (0.375" lead length), offering higher thermal mass and superior heat dissipation compared to surface-mount SMBJ or SMC packages. Its RθJL = 15.4 °C/W enables better power handling in through-hole layouts, while the molded epoxy body meets UL 94 V-0 - a key advantage for high-reliability industrial and automotive assemblies where mechanical robustness and creepage distance matter.
