Product details
Overview
1.5KE200CA-E3/51 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 breakdown voltage (VBR = 190–210 V), 1500 W peak pulse power (10/1000 µs), clamping voltage of 328 V at 4.6 A, 175 °C max junction temperature, and DO-201AD package. It protects MOSFETs, ICs, and sensor interfaces against lightning-induced transients and inductive switching spikes in industrial and automotive systems.
For engineers reviewing the 1.5KE200CA-E3/51 datasheet, 1.5KE200CA-E3/51 pinout, 1.5KE200CA-E3/51 application, or 1.5KE200CA-E3/51 equivalent, this page delivers verified electrical parameters, bidirectional clamping behavior, thermal derating curves, RoHS-compliant packaging details, and direct alternative part comparisons - all grounded in Vishay's official 88301 specification document.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional CA construction, with identical VBR, VC, and IPPM characteristics across polarity. Its glass-passivated junction enables sub-nanosecond response time (<1 ns) and low incremental surge resistance, critical for protecting fast-switching power semiconductors.
Rated for 1500 W peak pulse power under 10/1000 µs waveform and 6.5 W steady-state dissipation, it supports operation from –55 °C to +175 °C and exhibits a VWM of 171 V with ≤1.0 µA leakage - ensuring minimal standby loading on protected circuits while maintaining robust transient immunity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 190 V / 210 V - ensures reliable conduction onset above normal operating voltage but below system insulation limits |
| VWM | 171 V - maximum continuous reverse working voltage before significant leakage begins |
| VC @ IPPM | 328 V - clamped voltage during 4.6 A 10/1000 µs surge, defining worst-case stress on downstream components |
| PPPM | 1500 W - peak transient energy absorption capability per single 1 ms pulse |
| IPPM | 4.6 A - maximum non-repetitive surge current the device safely clamps without failure |
| TJmax | +175 °C - enables use in under-hood automotive and high-ambient industrial environments |
| Package | DO-201AD - industry-standard axial-leaded package with 0.375" lead length, UL 94 V-0 rated epoxy body |
Pinout & Package
1.5KE200CA-E3/51 uses a two-terminal DO-201AD package with no polarity marking - consistent with bidirectional TVS construction. Leads are matte tin-plated, solderable per J-STD-002 and JESD 22-B102, and qualified for 275 °C solder dip (10 s max).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient current path | Identical conduction in both directions; either terminal may connect to line or rail - no orientation required |
| Leads (axial) | Thermal and mechanical interface | Provide primary heat dissipation path (RθJL = 15.4 °C/W); require ≥0.375" lead length for rated power handling |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable VBR tolerance (±5 %), low leakage (<1 µA), and long-term reliability under thermal cycling |
| 1500 W peak pulse rating (10/1000 µs) | Protects against severe surges including lightning-induced transients per IEC 61000-4-5 Level 4 (4 kV) |
| Sub-nanosecond response time | Clamps within <1 ns - faster than MOVs or GDTs - preserving integrity of high-speed logic and gate drivers |
| RoHS-compliant E3 suffix | Meets JESD 201 Class 1A whisker resistance; suitable for commercial-grade industrial and consumer applications |
| UL 94 V-0 molded epoxy case | Provides flame-retardant mechanical encapsulation essential for safety-critical board-level protection |
Applications
| Industrial Motor Drives | Automotive Power Distribution |

Use Scenario: Input protection for microcontroller-based washing machine or HVAC control boards exposed to relay coil kickback. IC Role / Device Role / Timing Role: Low-leakage (≤1 µA) standoff device across AC/DC converter outputs or relay driver outputs. Use Value: 171 V VWM allows safe operation with 120 VAC-derived 160 VDC rails, while 328 V clamping prevents MCU reset or brownout during inductive turn-off. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200CA | DO-214AA package; lower PPPM (600 W); higher VC (324 V); same VBR range | Suitable for space-constrained PCBs but requires parallel placement for equivalent energy handling | Select when board area is limited and surge duty cycle is low; verify thermal relief for SMB footprint. |
| 1.5KE200A-E3/51 | Unidirectional variant; identical VBR, VC, and PPPM; cathode band marking; VF = 5.0 V @ 100 A | Required only where DC bias polarity is fixed and forward conduction must be blocked | Choose only if circuit topology mandates unidirectional blocking; otherwise 1.5KE200CA-E3/51 offers greater flexibility. |
Compared with SMBJ200CA and 1.5KE200A-E3/51, the 1.5KE200CA-E3/51 delivers full 1500 W surge capacity in an axial package with symmetrical clamping - making it optimal for high-energy, polarity-agnostic protection where leaded mounting and thermal mass are advantageous.

FAQ
What is the breakdown voltage tolerance for 1.5KE200CA-E3/51?
The 1.5KE200CA-E3/51 has a specified breakdown voltage range of 190 V to 210 V at 1 mA test current, corresponding to 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 standards such as IEC 61000-4-5.
Does 1.5KE200CA-E3/51 require orientation during PCB placement?
No - the 1.5KE200CA-E3/51 is a bidirectional TVS diode with symmetrical electrical characteristics; there is no cathode marking or polarity requirement. Either lead may connect to line or ground, simplifying layout and eliminating assembly errors associated with unidirectional devices like 1.5KE200A-E3/51.
What is the maximum clamping voltage of 1.5KE200CA-E3/51 under surge conditions?
The maximum clamping voltage (VC) of 1.5KE200CA-E3/51 is 328 V at a peak pulse current (IPPM) of 4.6 A using the standard 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case transient events and is confirmed in Vishay's Document Number 88301, page 2.
Is 1.5KE200CA-E3/51 RoHS compliant and lead-free?
Yes - the "E3" suffix indicates full RoHS compliance per Directive 2011/65/EU, with matte tin-plated leads and lead-free solderability validated per J-STD-002 and JESD 22-B102. The device also meets JESD 201 Class 1A whisker resistance testing, confirming long-term interconnect reliability.
Can 1.5KE200CA-E3/51 be used in automotive applications?
The 1.5KE200CA-E3/51 is commercial-grade and not AEC-Q101 qualified; however, Vishay offers the AEC-Q101-qualified 1.5KE200CAHE3_B variant. For non-safety-critical automotive subsystems (e.g., infotainment power rails) where qualification is not mandated, 1.5KE200CA-E3/51 remains viable due to its 175 °C TJmax and robust surge performance - but design-in requires customer validation per OEM requirements.
