Product details
Overview
1.5KE200C-E3/73 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 = 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 1.5KE200C-E3/73 datasheet, 1.5KE200C-E3/73 pinout, 1.5KE200C-E3/73 application, or 1.5KE200C-E3/73 equivalent, this page delivers verified electrical parameters, bidirectional clamping behavior, thermal derating curves, JEDEC-standard 1.5KE package dimensions, and AEC-Q101-qualified alternatives for ruggedized electronics design.
Technical Context
This device operates as a voltage-clamped shunt protector with symmetrical avalanche conduction in both polarities, enabling robust suppression of ±200 V transients without polarity sensitivity. Its glass-passivated junction ensures stable VBR tolerance (±5 %), low incremental surge resistance, and sub-nanosecond response time (<1 ns).
Rated for 1500 W peak pulse power under 10/1000 µs waveform at 0.01 % duty cycle, it sustains 200 A non-repetitive forward surge current (unidirectional only) and exhibits 0.108 %/°C temperature coefficient of VBR, supporting reliable operation across -55 °C to +175 °C ambient ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 209 V / 231 V - defines precise clamping onset threshold for bidirectional overvoltage events |
| VC @ IPPM | 328 V at 4.6 A - maximum voltage seen by protected circuit during full-rated 1500 W transient |
| PPPM | 1500 W - energy-handling capacity for standardized 10/1000 µs lightning-surge waveform |
| VWM | 185 V - maximum continuous working voltage before leakage exceeds 1 µA |
| ID @ VWM | <1 µA - ultra-low reverse leakage preserves signal integrity in high-impedance circuits |
| TJ max | +175 °C - enables placement near hot components (e.g., power MOSFETs, motor drivers) |
| RθJA | 75 °C/W - thermal resistance dictates heatsinking requirements for sustained surge duty |
Pinout & Package
Package: JEDEC Case Style 1.5KE - molded epoxy body with UL 94 V-0 flammability rating, 0.375" (9.5 mm) lead length, axial-leaded through-hole configuration. Cathode band absent (bidirectional symmetry).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Surge current entry (negative polarity) | Conducts during negative transients; identical electrical role as cathode due to bidirectional symmetry |
| Cathode | Surge current entry (positive polarity) | Conducts during positive transients; functionally interchangeable with anode in 1.5KE200C-E3/73 |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures stable VBR tolerance (±5 %) and long-term reliability under repeated surge stress |
| 1500 W peak pulse power (10/1000 µs) | Meets IEC 61000-4-5 Level 4 surge immunity requirements for industrial equipment |
| Sub-nanosecond response time | Clamps transients before sensitive ICs (e.g., microcontrollers, CAN transceivers) experience damage |
| RoHS-compliant matte tin plating | Guarantees solderability per J-STD-002 and eliminates whisker risk (JESD 201 Class 1A) |
| UL 497B recognized (QVGQ2) | Validated for telecom and industrial surge protection systems requiring safety agency approval |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN bus nodes and analog sensor inputs (e.g., pressure, temperature) from load-dump and ESD events in 12 V/24 V vehicle subsystems. IC Role / Device Role / Timing Role: Bidirectional shunt clamp placed across differential signal pair or supply rail to divert surge energy to ground. Use Value: Maintains signal integrity below 185 V working voltage while clamping 200 V+ transients to ≤328 V - preventing latch-up in downstream ASICs. | Use Scenario: Safeguarding digital input modules in programmable logic controllers against induced surges from relay coil switching and nearby motor drives. IC Role / Device Role / Timing Role: Primary overvoltage clamp on 24 V DC input terminals, coordinated with upstream fuses and downstream filtering. Use Value: Absorbs 1500 W surges without degradation, enabling >100,000 surge cycles per MIL-STD-883H Method 3015.8 compliance. |
| Telecom Line Interface | Consumer Power Adapter Input |
Use Scenario: Secondary-level protection on POTS or DSL line cards exposed to lightning-induced longitudinal surges up to 1 kV. IC Role / Device Role / Timing Role: Fast-acting bidirectional suppressor bridging tip/ring lines to chassis ground, preceding GDT or MOV stages. Use Value: Sub-ns response captures fast-rising edges missed by slower protectors, reducing let-through energy to <10 mJ. | Use Scenario: Input-stage surge suppression in AC-DC adapters for smart home devices subjected to mains-borne transients per IEC 61000-4-5. IC Role / Device Role / Timing Role: First-line defense across bulk capacitor terminals, limiting peak voltage during 1.2/50 µs combination wave tests. Use Value: Withstands 200 A surge current (8.3 ms half-sine) and maintains VWM stability after repeated stress - extending adapter lifetime. |
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 (surface-mount), lower IPPM (32.4 A) | Better suited for space-constrained PCBs; insufficient for 1500 W IEC 61000-4-5 Level 4 testing | Select when board area is critical and surge energy is ≤600 W; requires layout redesign for SMT placement. |
| 1.5KE200CAHE3_B | Identical electrical specs, but AEC-Q101 qualified and HE3 whisker-tested (Class 2) | Required for automotive OEM production; supports extended temperature validation (-40 °C to +125 °C case) | Choose for automotive-grade designs needing PPAP documentation and enhanced reliability screening. |
Compared with 1.5KE200C-E3/73, SMBJ200CA trades surge capacity for compactness, while 1.5KE200CAHE3_B adds automotive qualification without altering clamping performance - enabling direct substitution where AEC-Q101 compliance is mandated.

FAQ
What is the breakdown voltage range of the 1.5KE200C-E3/73?
The 1.5KE200C-E3/73 has a specified breakdown voltage (VBR) range of 209 V to 231 V at test current IT = 1 mA, measured in both directions due to its bidirectional construction. This range ensures consistent clamping behavior regardless of transient polarity and aligns with JEDEC standard 1.5KE200C specifications.
Is the 1.5KE200C-E3/73 suitable for automotive applications?
The 1.5KE200C-E3/73 is rated for operation from -55 °C to +175 °C and meets RoHS requirements, but it is not AEC-Q101 qualified. For production automotive use, Vishay offers the pin-compatible 1.5KE200CAHE3_B variant, which carries full AEC-Q101 certification and enhanced whisker resistance - the 1.5KE200C-E3/73 remains appropriate for prototyping and non-OEM automotive subsystems.
What is the clamping voltage of the 1.5KE200C-E3/73 at its rated peak pulse current?
At its rated peak pulse current of 4.6 A (IPPM), the 1.5KE200C-E3/73 clamps to a maximum voltage of 328 V under the standard 10/1000 µs waveform. This value represents the upper limit of voltage imposed on the protected circuit during a full 1500 W transient event and is confirmed in Vishay's Document Number 88301, page 2.
Does the 1.5KE200C-E3/73 have polarity markings?
No, the 1.5KE200C-E3/73 does not feature a cathode band or other polarity marking because it is a bidirectional TVS diode. Its symmetrical construction allows installation in either orientation across a differential line or supply rail - unlike unidirectional variants (e.g., 1.5KE200A) which require correct anode/cathode alignment.
What is the maximum steady-state power dissipation of the 1.5KE200C-E3/73?
The 1.5KE200C-E3/73 has a maximum steady-state power dissipation (PD) of 6.5 W when mounted on an infinite heatsink at lead temperature TL = 75 °C. This rating applies only to continuous DC or low-frequency conditions - transient surge handling (1500 W) is strictly time-limited per Fig. 5 derating curve in the Vishay datasheet.
