Product details
Overview
P6SMB200CAHE3_A/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for clamping voltage transients on power and signal lines. It features a 200 V standoff voltage (VWM), 220 V minimum breakdown voltage (VBR), 274 V maximum clamping voltage (VC) at 2.2 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies and automotive ECUs.
For engineers reviewing the P6SMB200CAHE3_A/I datasheet, P6SMB200CAHE3_A/I pinout, P6SMB200CAHE3_A/I application, or P6SMB200CAHE3_A/I equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, SMB (DO-214AA) package compatibility, and thermal performance under repetitive surge conditions.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC-coupled or differential signal paths without polarity concerns. Its glass-passivated junction ensures stable leakage and fast response (<1 ns), while the low incremental surge resistance supports effective energy diversion during ESD or lightning-induced transients.
The device is rated for 150 °C maximum junction temperature and meets MSL Level 1 per J-STD-020 with 260 °C lead-free reflow peak. Its AEC-Q101 qualification (via HE3 suffix) confirms suitability for automotive under-hood and body-control module applications requiring high reliability under thermal cycling and mechanical stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 200 V - Maximum continuous reverse voltage before clamping begins; defines operating margin for 24 V–48 V DC bus protection. |
| VBR (Breakdown Voltage) | 220 V min - Voltage at which device enters avalanche conduction; ensures reliable triggering above normal operating voltage. |
| VC (Clamping Voltage) | 274 V max at IPPM = 2.2 A - Peak voltage seen by protected circuit during 10/1000 μs transient; determines safe overvoltage margin for downstream components. |
| PPPM (Peak Pulse Power) | 600 W - Energy-handling capacity for standardized 10/1000 μs surge; sufficient for IEC 61000-4-5 Level 3 (1 kV/2 Ω) testing. |
| ID (Reverse Leakage) | 1.0 μA max at VWM - Low leakage preserves efficiency in high-impedance bias networks and battery-powered sensors. |
| TJ max | 150 °C - Enables operation in under-hood automotive environments and industrial enclosures without derating below full power. |
| Package | SMB (DO-214AA) - Standardized surface-mount outline with 5.59 mm × 4.06 mm footprint; compatible with automated pick-and-place and reflow soldering. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads, UL 94 V-0 rated, MSL Level 1, 260 °C peak reflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward direction; symmetrical with cathode in bidirectional operation | No polarity marking required; terminals are interchangeable for transient suppression across AC or differential lines. |
| Cathode | Current exit terminal in forward direction; symmetrical with anode in bidirectional operation | Identical electrical behavior to anode; bidirectional clamping eliminates need for orientation-aware layout. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC lines, RS-485 buses, or CAN FD differential pairs without external polarity management. |
| AEC-Q101 qualified (HE3 suffix) | Validated for automotive applications including engine control units and ADAS power domains where lifecycle reliability is mandatory. |
| 600 W peak pulse power | Supports robust immunity against ISO 7637-2 pulse 1/2a/5a and IEC 61000-4-5 surges without degradation over 1000+ events. |
| Glass-passivated junction | Ensures stable VBR and low leakage over temperature (-65 °C to +150 °C) and lifetime, critical for industrial field deployments. |
| Low thermal resistance (RθJL = 20 °C/W) | Facilitates efficient heat transfer to PCB copper pads, maintaining clamping performance during repetitive surge events. |

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 | Same VWM/VBR/VC ratings, identical SMB package, but not AEC-Q101 qualified; commercial-grade only | Lacks automotive qualification; suitable for industrial/commercial designs without AEC compliance requirements | Select when cost sensitivity outweighs automotive qualification needs and thermal cycling is not extreme. |
| 1.5KE200CA | Higher power (1500 W), axial-leaded DO-201 package; larger footprint and manual assembly required | Used where board space allows and higher surge margin is needed; incompatible with automated SMT lines | Choose only if 600 W is insufficient and through-hole assembly is acceptable. |

FAQ
What is the clamping voltage of P6SMB200CAHE3_A/I at its rated peak pulse current?
The P6SMB200CAHE3_A/I has a maximum clamping voltage (VC) of 274 V at its specified peak pulse current (IPPM) of 2.2 A using the 10/1000 μs waveform. This value is measured under standard test conditions (TA = 25 °C, mounted on 0.2" × 0.2" copper pads) and defines the upper voltage limit imposed on protected circuits during transient events. The P6SMB200CAHE3_A/I maintains this clamping performance across its full operating temperature range.
Is P6SMB200CAHE3_A/I suitable for automotive applications?
Yes, P6SMB200CAHE3_A/I is AEC-Q101 qualified, as indicated by the "HE3" suffix in its part number. It undergoes rigorous stress testing for temperature cycling, humidity, mechanical shock, and surge endurance - meeting requirements for use in automotive body electronics, powertrain sub-systems, and ADAS modules. The P6SMB200CAHE3_A/I is specifically intended for under-hood and cabin applications where reliability under thermal and electrical stress is critical.
What does the "CA" suffix mean in P6SMB200CAHE3_A/I?
The "CA" suffix in P6SMB200CAHE3_A/I denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression in both polarities, with identical VWM, VBR, and VC characteristics in either direction. This eliminates the need for polarity-aware placement and makes the P6SMB200CAHE3_A/I ideal for protecting AC-coupled signals, differential buses (e.g., CAN, RS-485), or ungrounded power rails where voltage reversals may occur.
What is the maximum operating temperature for P6SMB200CAHE3_A/I?
The P6SMB200CAHE3_A/I has a maximum junction temperature (TJ max) of +150 °C and an operating junction/storage temperature range of -65 °C to +150 °C. This rating enables deployment in high-temperature environments such as automotive engine compartments, industrial motor drives, and enclosed power supplies. Derating curves in the datasheet (Fig. 2) define allowable power reduction above 25 °C ambient to maintain safe TJ operation.
How does the SMB (DO-214AA) package of P6SMB200CAHE3_A/I compare to SMA or SMC packages?
The SMB (DO-214AA) package of P6SMB200CAHE3_A/I measures 4.06 mm × 5.59 mm with a 2.18 mm minimum terminal width, offering a balance between power handling and board space efficiency. It delivers higher surge capability than SMA (DO-214AC) but smaller footprint than SMC (DO-214AB); the P6SMB200CAHE3_A/I's 600 W rating is optimized for this mid-size outline. Its MSL Level 1 rating and 260 °C reflow tolerance ensure compatibility with modern lead-free assembly processes.
