Product details
Overview
1.5SMC200AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, rated for 200 V standoff voltage (VWM), 210 V minimum breakdown voltage (VBR), and 1500 W peak pulse power (10/1000 μs). It clamps transients to 274 V at 5.5 A peak pulse current and is AEC-Q101 qualified for automotive electronics protection.
For engineers reviewing the 1.5SMC200AHE3_A/H datasheet, 1.5SMC200AHE3_A/H pinout, 1.5SMC200AHE3_A/H application, or 1.5SMC200AHE3_A/H equivalent, this device is selected for high-energy surge suppression in DC power rails, automotive sensor interfaces, and industrial control I/O lines where robust ESD and lightning-induced transient immunity is required.
Technical Context
This unidirectional TVS operates as a voltage-clamping overvoltage protector with glass-passivated junction and low incremental surge resistance. Its 10/1000 μs waveform response delivers 1500 W peak pulse power while maintaining clamping voltage ≤274 V at IPPM, enabling reliable protection of downstream MOSFETs and ICs against repetitive surges up to 0.01% duty cycle.
Designed for automotive-grade reliability, the 1.5SMC200AHE3_A/H meets AEC-Q101 qualification, supports operating junction temperatures from –65 °C to +150 °C, and features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 171 V - Maximum continuous reverse working voltage before clamping begins; defines safe DC operating margin. |
| VBR (Breakdown Voltage) | 190–210 V at 1 mA - Voltage at which device enters avalanche conduction; ensures precise overvoltage threshold activation. |
| VC (Clamping Voltage) | 274 V at 5.5 A IPPM - Peak voltage seen by protected circuit during 10/1000 μs surge; determines stress on downstream components. |
| PPPM (Peak Pulse Power) | 1500 W - Surge energy handling capability under standardized 10/1000 μs waveform; enables protection against lightning and inductive switching. |
| ID (Reverse Leakage) | 1.0 μA at VWM - Minimal leakage current at rated standoff voltage; preserves system efficiency and signal integrity. |
| TJ max. | +150 °C - Maximum junction temperature rating; supports operation in under-hood automotive and high-ambient industrial environments. |
| Package | SMC (DO-214AB) - Surface-mount package with 8.0 mm × 8.0 mm copper pad thermal footprint; optimized for automated placement and thermal dissipation. |
Pinout & Package
Package: SMC (DO-214AB), molded case with matte tin-plated leads; cathode indicated by band marking on unidirectional devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to lower-potential side of protected line | Enables unidirectional clamping from cathode to anode; must be tied to ground or return path for proper transient shunting. |
| Cathode | Current exit terminal in forward bias; marked with band; connected to protected line | Serves as the high-side connection point for surge current diversion; clamps voltage relative to anode reference. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control units and ADAS sensor interfaces requiring long-term reliability under thermal cycling and vibration. |
| 1500 W peak pulse power (10/1000 μs) | Supports robust protection against ISO 7637-2 Pulse 5a/b (load dump) and IEC 61000-4-5 Level 4 surges without degradation. |
| Glass-passivated junction | Ensures stable avalanche characteristics and low parameter drift over lifetime, critical for mission-critical protection circuits. |
| MSL Level 1 (260 °C peak reflow) | Enables compatibility with standard lead-free SMT assembly processes without moisture-related popcorning or delamination. |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage overshoot during fast transients, reducing stress on sensitive 200 V-rated MOSFETs and gate drivers. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ200A-E3/57T | Same 200 V VWM and 274 V VC, but rated for only 400 W PPPM and housed in smaller SMA (DO-214AC) package. | Limited to lower-energy surges; unsuitable for ISO 7637-2 Pulse 5 or IEC 61000-4-5 Level 4 compliance testing. | Select when board space is constrained and surge threat level is limited to ESD and minor inductive spikes. |
| 1.5KE200A | Through-hole TO-204AE (DO-41) package; identical electrical specs but higher RθJA (100 °C/W vs. 75 °C/W) and no AEC-Q101 qualification. | Not suitable for automotive SMT production or high-reliability under-hood deployment; requires manual insertion or wave soldering. | Choose only for legacy through-hole designs or prototyping where AEC-Q101 and automated assembly are not required. |
Compared with SMAJ200A-E3/57T and 1.5KE200A, the 1.5SMC200AHE3_A/H delivers superior surge robustness (1500 W vs. 400 W or 1500 W with inferior thermal performance), automotive qualification, and SMT manufacturability-making it the preferred choice for production-grade automotive and industrial systems.

FAQ
What is the maximum clamping voltage of the 1.5SMC200AHE3_A/H under standard test conditions?
The 1.5SMC200AHE3_A/H exhibits a maximum clamping voltage (VC) of 274 V when subjected to its rated peak pulse current (IPPM) of 5.5 A using the industry-standard 10/1000 μs double-exponential waveform. This value is measured at TA = 25 °C with devices mounted on 8.0 mm × 8.0 mm copper pads per terminal, and represents the upper limit of voltage imposed on protected circuitry during surge events.
Is the 1.5SMC200AHE3_A/H suitable for automotive applications?
Yes, the 1.5SMC200AHE3_A/H is explicitly AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3" and documentation revision notes. It is designed for under-hood and chassis-mounted automotive systems-including engine control modules, ADAS sensors, and body electronics-where operation from –65 °C to +150 °C and resistance to thermal cycling, vibration, and repetitive surges are mandatory.
What does the "_A/H" suffix in 1.5SMC200AHE3_A/H indicate?
The "_A/H" suffix in 1.5SMC200AHE3_A/H denotes two key attributes: "A" specifies the voltage variant (200 V VWM, 190–210 V VBR), and "H" indicates packaging in 7-inch plastic tape-and-reel format with 850 units per reel. The "HE3" portion confirms RoHS-compliant construction and AEC-Q101 qualification, distinguishing it from commercial-grade E3 or halogen-free HM3 variants.
How does the thermal resistance of the 1.5SMC200AHE3_A/H affect its power handling capability?
The 1.5SMC200AHE3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on recommended 8.0 mm × 8.0 mm copper pads. This allows sustained 6.5 W power dissipation at TA = 50 °C, but limits continuous operation at elevated ambient temperatures-requiring derating per Figure 2 in the datasheet to avoid exceeding the +150 °C maximum junction temperature during prolonged surge exposure or high-duty-cycle events.
Can the 1.5SMC200AHE3_A/H be used in bidirectional configurations?
No, the 1.5SMC200AHE3_A/H is a unidirectional TVS diode, as indicated by the "A" (not "CA") suffix and explicit polarity marking (cathode band). For bidirectional protection at the same voltage rating, Vishay offers the 1.5SMC200CA variant, which provides symmetrical clamping in both directions and omits the cathode band marking. Using the unidirectional 1.5SMC200AHE3_A/H in AC or floating applications risks failure due to reverse conduction.
