Product details
Overview
1.5KE200CA-E3/73 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode designed for robust overvoltage 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, 175 °C max junction temperature, and RoHS-compliant matte tin-plated leads - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the 1.5KE200CA-E3/73 datasheet, 1.5KE200CA-E3/73 pinout, 1.5KE200CA-E3/73 application, or 1.5KE200CA-E3/73 equivalent, key selection criteria include bidirectional clamping capability, 10/1000 µs waveform compliance, thermal resistance (RθJL = 15.4 °C/W), stand-off voltage (VWM = 185 V), and AEC-Q101 qualification eligibility (via HE3 suffix variants).
Technical Context
This device operates as a silicon avalanche diode with glass-passivated junction, delivering symmetrical clamping in both polarities. Its bidirectional architecture enables protection against voltage transients induced by inductive switching or lightning surges without polarity sensitivity - critical for AC-coupled or floating signal paths.
It responds within <1 ns to transient events and maintains stable clamping performance across -55 °C to +175 °C operating range. The 1.5KE package supports lead-free soldering (275 °C, 10 s max) and meets UL 94 V-0 flammability requirements, ensuring reliability in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 209 V / 231 V - ensures reliable avalanche conduction onset above normal operating voltage |
| VWM | 185 V - maximum continuous reverse working voltage before leakage exceeds 1 μA |
| VC @ IPPM | 328 V at 4.6 A - clamped voltage during 10/1000 µs surge, limiting downstream stress |
| PPPM | 1500 W - peak transient power handling capability per JEDEC standard waveform |
| IPPM | 4.6 A - maximum non-repetitive peak pulse current under specified test conditions |
| TJ max | +175 °C - high-temperature operation support for under-hood automotive or industrial enclosures |
| RθJL | 15.4 °C/W - low junction-to-lead thermal resistance enabling efficient heat dissipation through PCB traces |

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, higher VC (324 V), same VBR range | Space-constrained PCBs where 1500 W rating is not required | Select when board area is limited and surge energy is ≤600 W |
| 1.5SMC200CA | Same PPPM (1500 W), SMC package (surface-mount), slightly higher VC (339 V), identical VBR | Automated assembly requiring SMT instead of axial-leaded through-hole | Choose for reflow-compatible designs needing equivalent surge rating |
Compared with 1.5KE200CA-E3/73, SMBJ200CA offers footprint reduction at the cost of 60% lower surge power handling, while 1.5SMC200CA delivers identical protection performance in a surface-mount format - enabling layout flexibility without compromising clamping accuracy or thermal robustness.

FAQ
What is the breakdown voltage tolerance for 1.5KE200CA-E3/73?
The 1.5KE200CA-E3/73 has a specified breakdown voltage range of 209 V to 231 V at 1 mA test current (VBR min/max), corresponding to ±5% tolerance around the nominal 200 V rating. This tight distribution ensures consistent clamping behavior across production lots and supports predictable system-level surge margin design in the 1.5KE200CA-E3/73.
Is 1.5KE200CA-E3/73 suitable for automotive applications?
Yes, the 1.5KE200CA-E3/73 is qualified for automotive use when ordered with the HE3 suffix (e.g., 1.5KE200CAHE3_B), which denotes AEC-Q101 qualification. While the E3/73 variant itself is commercial-grade, its construction - including glass-passivated junction, 175 °C max junction temperature, and robust surge capability - aligns with automotive environmental stress requirements, making the 1.5KE200CA-E3/73 a common choice for non-safety-critical ECU protection.
How does the bidirectional configuration of 1.5KE200CA-E3/73 affect circuit placement?
The 1.5KE200CA-E3/73 has no polarity marking and functions identically in either orientation, allowing placement across AC-coupled lines, differential pairs, or floating supplies without concern for anode/cathode alignment. This simplifies layout and eliminates risk of reverse installation - a key advantage of the 1.5KE200CA-E3/73 over unidirectional TVS diodes in symmetric protection schemes.
What is the maximum clamping voltage of 1.5KE200CA-E3/73 under surge conditions?
The 1.5KE200CA-E3/73 exhibits a maximum clamping voltage (VC) of 328 V when subjected to its rated peak pulse current of 4.6 A using the standardized 10/1000 µs waveform. This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuitry during worst-case transient events - a critical parameter verified for every unit of the 1.5KE200CA-E3/73.
Can 1.5KE200CA-E3/73 be used in parallel for higher surge capacity?
Yes, multiple 1.5KE200CA-E3/73 devices can be paralleled to increase total peak pulse power handling, but matching VBR tolerances and using equal-length PCB traces are essential to ensure current sharing. Vishay's application notes confirm this practice for >1500 W requirements, though derating and thermal coupling must be evaluated - a design consideration explicitly supported by the 1.5KE200CA-E3/73 datasheet.
