Product details
Overview
1.5SMC200CAHE3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for high-energy surge protection in power and signal lines. It delivers 1500 W peak pulse power (10/1000 μs), clamps at 328 V under 4.6 A peak pulse current, and features a 200 V standoff voltage (VWM) with ±5% tolerance. Used to protect MOSFETs, sensor interfaces, and automotive ECUs against lightning-induced transients and inductive switching spikes.
For engineers reviewing the 1.5SMC200CAHE3_A/H datasheet, 1.5SMC200CAHE3_A/H pinout, 1.5SMC200CAHE3_A/H application, or 1.5SMC200CAHE3_A/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, SMC (DO-214AB) package compatibility, and thermal resistance of 75 °C/W junction-to-ambient - all critical for automotive-grade transient suppression in harsh environments.
Technical Context
This device operates as a voltage-clamped shunt protector: when reverse (or forward, in bidirectional mode) voltage exceeds its breakdown threshold (~234 V min / ~263 V max at 1 mA), it rapidly transitions to low-impedance conduction, diverting surge current away from downstream circuitry. Its glass-passivated junction ensures stable avalanche characteristics and long-term reliability under repetitive surges.
Designed for unidirectional and bidirectional configurations, the 1.5SMC200CAHE3_A/H uses symmetrical internal structure enabling identical clamping behavior in both polarities. It meets MSL Level 1 per J-STD-020, supports lead-free reflow up to 260 °C peak, and is qualified to AEC-Q101 for automotive under-hood applications requiring TJ = -65 °C to +150 °C operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 200 V ±5% - maximum continuous reverse voltage before significant leakage; defines operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 234 V min / 263 V max at 1 mA - precise avalanche initiation point ensuring predictable turn-on during overvoltage events |
| VC (Clamping Voltage) | 328 V at IPPM = 4.6 A (10/1000 μs) - actual voltage seen by protected circuit during worst-case surge; determines safe IC voltage margin |
| PPPM (Peak Pulse Power) | 1500 W - energy-handling capacity for standardized 10/1000 μs surge waveform; enables robust protection against IEC 61000-4-5 Level 4 |

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), same VWM (200 V), SMB package (smaller footprint, higher RθJA = 110 °C/W) | Not recommended for IEC 61000-4-5 Level 4; suitable only for lower-energy consumer-grade surges | Select when board space is constrained and surge threat level is ≤ Level 2; requires thermal derating above 50 °C ambient |
| 1.5KE200CA | Same electrical specs but axial DO-15 package; no AEC-Q101 qualification; higher mounting inductance | Not suitable for automated SMT production or automotive vibration environments; limited to prototyping or through-hole legacy designs | Choose only for manual assembly or cost-sensitive non-automotive applications where SMT compatibility is not required |

FAQ
What does the "CA" suffix indicate in 1.5SMC200CAHE3_A/H?
The "CA" suffix in 1.5SMC200CAHE3_A/H denotes a bidirectional configuration: the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., "A"), it has no cathode marking and functions identically in either polarity - essential for protecting AC-coupled or floating signal lines such as CAN bus or sensor differential pairs.
Is 1.5SMC200CAHE3_A/H suitable for IEC 61000-4-5 surge testing?
Yes, 1.5SMC200CAHE3_A/H is rated for 1500 W peak pulse power with a 10/1000 μs waveform, meeting IEC 61000-4-5 Level 4 (4 kV line-to-earth, 2 kV line-to-line) when used with appropriate PCB layout (e.g., 8 mm × 8 mm copper pads). Its 328 V clamping voltage at 4.6 A ensures protected circuits remain within safe operating area during standardized surge events.
How does the HE3 suffix affect the 1.5SMC200CAHE3_A/H specification?
The "HE3" suffix in 1.5SMC200CAHE3_A/H indicates RoHS-compliant construction with AEC-Q101 qualification - distinguishing it from commercial-grade E3 or M3 variants. This means the device has passed automotive-specific stress tests (temperature cycling, humidity, mechanical shock) and is approved for use in safety-critical vehicle subsystems like engine management and ADAS sensor modules.
What is the maximum operating temperature for 1.5SMC200CAHE3_A/H?
The 1.5SMC200CAHE3_A/H has a maximum junction temperature (TJ max) of +150 °C and an operating junction/storage range of -65 °C to +150 °C. When mounted on standard 8 mm × 8 mm copper pads, its thermal resistance is 75 °C/W; therefore, at 25 °C ambient, it can dissipate up to 6.5 W continuously - derating linearly above that ambient temperature.
Can 1.5SMC200CAHE3_A/H replace older 1.5KE200CA in existing designs?
No direct replacement: although both share 200 V standoff and bidirectional function, 1.5SMC200CAHE3_A/H uses SMC (DO-214AB) surface-mount packaging versus DO-15 axial leads in 1.5KE200CA. PCB layout, thermal management, and assembly process differ significantly; redesign is required for footprint, solder reflow profile, and mechanical mounting - especially in automotive vibration environments.
