Product details
Overview
1.5KE200CA-E3/54 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 standoff voltage (VWM), 210 V minimum breakdown voltage (VBR), 1500 W peak pulse power (10/1000 µs), clamping voltage of 328 V at 4.6 A IPPM, and operates across –55 °C to +175 °C. It protects MOSFETs and ICs against lightning-induced transients in industrial power supplies.
For engineers reviewing the 1.5KE200CA-E3/54 datasheet, 1.5KE200CA-E3/54 pinout, 1.5KE200CA-E3/54 application, or 1.5KE200CA-E3/54 equivalent, this page delivers verified electrical specs, thermal derating behavior, clamping performance under 10/1000 µs surges, JEDEC 1.5KE package dimensions, and direct alternatives with documented VBR/VC/IPP differences.
Technical Context
This bidirectional TVS uses a glass-passivated silicon junction optimized for sub-nanosecond response (<1 ns) and low incremental surge resistance. Its symmetrical I–V characteristic enables identical clamping in both polarities, supporting AC line and differential signal protection without polarity concerns.
Rated for 1500 W peak pulse power (10/1000 µs waveform, 0.01% duty cycle), it sustains repetitive surges when thermally managed via lead-to-ambient thermal resistance (RθJA = 75 °C/W) and junction-to-lead resistance (RθJL = 15.4 °C/W). The device meets UL 497B recognition (QVGQ2) and RoHS compliance per JESD 201 Class 1A whisker testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 185 V - Maximum continuous reverse operating voltage before conduction begins; defines safe working margin below clamping threshold. |
| VBR (min/max) | 209 V / 231 V at 1 mA - Verified breakdown range ensures reliable turn-on during overvoltage events without premature leakage. |
| VC @ IPPM | 328 V at 4.6 A - Clamping voltage limits downstream component stress during 10/1000 µs transients; critical for MOSFET gate oxide safety. |
| PPPM | 1500 W - Peak pulse power handling capacity determines survivability against lightning surges (IEC 61000-4-5 Level 4). |
| TJ max | +175 °C - High junction temperature rating supports operation in enclosed industrial enclosures without forced cooling. |
| IFSM | Not applicable - Bidirectional construction lacks forward surge rating; only unidirectional variants specify 200 A 8.3 ms half-sine rating. |
| CJ | Not specified in datasheet - Junction capacitance not provided; typical for high-voltage TVS diodes where capacitive loading is secondary to clamping performance. |
Pinout & Package
Package: JEDEC case style 1.5KE - molded epoxy body with matte tin-plated leads, UL 94 V-0 rated, 0.375" (9.5 mm) lead length, 0.042" (1.07 mm) lead diameter. No polarity marking on bidirectional devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional transient conduction path | Both terminals function identically; no cathode band marking required; enables placement in AC or floating differential lines without orientation check. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable, repeatable breakdown voltage and long-term reliability under thermal cycling and humidity exposure. |
| 1500 W peak pulse power (10/1000 µs) | Supports IEC 61000-4-5 surge immunity up to 4 kV (open-circuit) in industrial power input stages. |
| Sub-nanosecond response time | Clamps transients within <1 ns, protecting sensitive gate oxides before damage occurs in MOSFETs and ICs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200CA | Lower PPPM (600 W), smaller SMB package (3.5 mm × 3.5 mm), VC = 324 V @ 1.85 A | Better suited for space-constrained PCBs; lower energy handling requires series impedance or staged protection for 1500 W threats. | Select SMBJ200CA when board area is limited and surge threat level is ≤2 kV (IEC 61000-4-5 Level 3); verify thermal dissipation in confined layouts. |
| 1.5SMC200CA | Same PPPM (1500 W), SMC package (7.1 mm × 6.2 mm), VC = 328 V @ 4.6 A, RθJA = 40 °C/W (lower thermal resistance) | Superior thermal performance enables higher ambient operation; larger footprint than 1.5KE but more robust under sustained surge repetition. | Choose 1.5SMC200CA for high-reliability industrial systems requiring extended surge repetition or operation above 85 °C ambient. |
Compared with 1.5KE200CA-E3/54, SMBJ200CA trades energy handling for compactness, while 1.5SMC200CA retains full 1500 W capability with improved thermal management-making it preferable for thermally demanding deployments where PCB real estate allows.

FAQ
What is the clamping voltage of the 1.5KE200CA-E3/54 under a 10/1000 µs surge?
The 1.5KE200CA-E3/54 clamps to a maximum of 328 V at its rated peak pulse current (IPPM) of 4.6 A under a 10/1000 µs waveform. This value is measured per Figure 9 in the Vishay datasheet 88301 and defines the upper voltage limit imposed on protected circuitry during standardized surge events. Designers must ensure downstream components tolerate ≤328 V transient stress.
Is the 1.5KE200CA-E3/54 RoHS compliant and qualified for automotive use?
The 1.5KE200CA-E3/54 carries the "E3" suffix, confirming RoHS compliance per JESD 201 Class 1A whisker testing. However, it is not AEC-Q101 qualified-only variants with "HE3" suffix (e.g., 1.5KE200CAHE3_B) meet AEC-Q101. For automotive body control modules, the 1.5KE200CA-E3/54 may be used in non-safety-critical subsystems where qualification is not mandated.
How does the bidirectional nature of the 1.5KE200CA-E3/54 affect its placement in circuit design?
The 1.5KE200CA-E3/54 has symmetrical anode/cathode terminals and no polarity marking, allowing placement across AC lines, differential data pairs, or floating grounds without orientation constraints. Unlike unidirectional TVS diodes, it conducts identically in both directions-eliminating risk of incorrect installation and simplifying layout for dual-polarity transient suppression.
What is the maximum operating temperature range for the 1.5KE200CA-E3/54?
The 1.5KE200CA-E3/54 operates across a junction temperature range of –55 °C to +175 °C, enabling deployment in extreme environments such as engine compartments, industrial motor drives, and outdoor telecom cabinets. Its high TJmax supports uninterrupted operation even under elevated ambient temperatures when mounted with adequate copper pour for heat spreading.
Can the 1.5KE200CA-E3/54 be used in parallel to increase surge current handling?
Yes-the 1.5KE200CA-E3/54 can be paralleled to distribute surge current, but matching VBR (209–231 V) and thermal layout is essential to prevent current hogging. Vishay recommends using matched lots and symmetric PCB traces with equal-length thermal paths. Derating by ≥20% per device is advised to account for parameter spread and thermal coupling effects.
