Product details
Overview
1.5KE200-E3/54 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 standoff voltage (VWM), 210 V maximum breakdown voltage (VBR), 274 V clamping voltage (VC) at 5.5 A peak pulse current, 1500 W peak pulse power (10/1000 µs), and operates from –55 °C to +175 °C junction temperature.
For engineers reviewing the 1.5KE200-E3/54 datasheet, 1.5KE200-E3/54 pinout, 1.5KE200-E3/54 application, or 1.5KE200-E3/54 equivalent, this device is selected for robust surge immunity in automotive power supplies, industrial sensor interfaces, and telecom line protection where fast clamping (<1 ns), low incremental surge resistance, and AEC-Q101–qualified reliability are required.
Technical Context
This unidirectional TVS diode uses a glass-passivated silicon junction to achieve sub-nanosecond response time and stable clamping under repetitive 10/1000 µs transients. Its 1500 W peak pulse rating is derated linearly above 25 °C ambient per JEDEC-standard thermal curves, with RθJA = 75 °C/W and RθJL = 15.4 °C/W enabling effective lead-based heat dissipation.
The device exhibits a 0.108 %/°C temperature coefficient of VBR, ensuring predictable voltage threshold drift across temperature. Its 3.5 V forward voltage at 100 A (per spec note) and 200 A non-repetitive surge capability (8.3 ms half-sine) support high-energy transient suppression without latch-up in power supply input stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |

IC Role / Device Role / Timing Role: Unidirectional TVS placed between VIN and GND to clamp transients before LDO or DC/DC converter input. Use Value: Limits voltage to ≤274 V during 1500 W surges, preventing damage to 36 V-rated input capacitors and regulator ICs. |
Use Scenario: 4–20 mA current loop interface in factory automation PLC modules subjected to EFT bursts. IC Role / Device Role / Timing Role: TVS mounted across analog input terminals to suppress fast-rising noise coupled from adjacent motor drives. Use Value: Sub-ns response clamps induced spikes before they reach precision op-amps or ADC front-ends, preserving measurement integrity. |
| Telecom DC Feeder Protection | Consumer Appliance Motor Drive Snubber |
Use Scenario: –48 V DC power feed to remote radio units in cellular base stations, vulnerable to lightning-induced surges on long cable runs. IC Role / Device Role / Timing Role: Unidirectional TVS installed at power entry point to absorb longitudinal surges before DC/DC isolation stage. Use Value: 274 V clamping ensures downstream SiC MOSFET gate drivers remain within safe operating area during multi-kW transients. |
Use Scenario: Brushed DC motor control in washing machine main board, where commutation spikes threaten MCU GPIO and relay drivers. IC Role / Device Role / Timing Role: TVS placed across motor terminals to suppress inductive kickback during PWM switching. Use Value: 200 A surge rating handles repeated commutation events; 171 V VWM avoids false triggering during normal 130 V peak back-EMF. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200A | DO-214AA package (SMB), 200 V VWM, 225 V VC @ 6.7 A, lower 600 W PPPM | Surface-mount alternative with smaller footprint but reduced surge handling; not suitable for >1 kA system-level tests. | Select SMBJ200A only when board space is constrained and peak surge energy is ≤600 W. |
| 1.5KE200AHE3_B | Same 1.5KE package, identical electrical specs, but AEC-Q101 qualified and HE3 whisker-tested (Class 2) | Required for automotive safety-critical modules (e.g., ADAS power domains) where qualification traceability is mandated. | Choose 1.5KE200AHE3_B for automotive OEM designs requiring formal AEC-Q101 documentation and extended whisker resistance. |
Compared with 1.5KE200-E3/54, SMBJ200A trades surge capacity for compactness, while 1.5KE200AHE3_B adds automotive qualification without altering clamping behavior-making it a drop-in replacement only when compliance, not performance, drives selection.

FAQ
What is the clamping voltage of the 1.5KE200-E3/54 under peak surge conditions?
The 1.5KE200-E3/54 has a maximum clamping voltage (VC) of 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 a full 1500 W transient event. Engineers use this parameter to verify that downstream components remain within their absolute maximum ratings.
Is the 1.5KE200-E3/54 RoHS compliant and lead-free?
Yes, the 1.5KE200-E3/54 carries the E3 suffix, indicating full RoHS compliance per Directive 2011/65/EU. Its matte tin-plated leads meet J-STD-002 solderability requirements and pass JESD 201 Class 1A whisker testing. The molded epoxy case satisfies UL 94 V-0 flammability standards, making 1.5KE200-E3/54 suitable for environmentally regulated commercial and industrial applications.
Can the 1.5KE200-E3/54 be used in bidirectional configurations?
No, the 1.5KE200-E3/54 is a unidirectional TVS diode. Bidirectional variants in the 1.5KE family carry the "CA" suffix (e.g., 1.5KE200CA) and are only available up to 220 V VBR. Since 1.5KE200-E3/54 lacks the CA designation and its datasheet specifies polarity marking (cathode band), it must be oriented correctly in circuit-cathode toward the protected line-and cannot suppress positive- and negative-going transients symmetrically.
What is the maximum operating temperature for the 1.5KE200-E3/54?
The 1.5KE200-E3/54 has a maximum junction temperature (TJ) of +175 °C and a storage temperature range of –55 °C to +175 °C. Its thermal resistance from junction to ambient (RθJA) is 75 °C/W, meaning power dissipation must be limited to maintain safe junction temperatures-especially critical in enclosed automotive or industrial enclosures where ambient may exceed 85 °C.
How does the 1.5KE200-E3/54 compare to MOV-based surge protection?
Unlike metal-oxide varistors (MOVs), the 1.5KE200-E3/54 offers sub-nanosecond response time, no capacitance-related signal distortion, and no wear-out mechanism from repeated surges. Its precise 190–210 V VBR window and stable 274 V clamping provide deterministic protection for sensitive electronics, whereas MOVs exhibit voltage drift and degradation after multiple events-making 1.5KE200-E3/54 preferable for mission-critical signal integrity and long-lifetime applications.
