Product details
Overview
P6SMB200AHE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 200 V standoff voltage (VWM), 210 V minimum breakdown voltage (VBR), and 274 V maximum clamping voltage (VC) at 2.2 A peak pulse current (IPPM), used to protect power rails and signal lines in industrial power supplies and automotive ECUs against ESD and inductive switching transients.
For engineers reviewing the P6SMB200AHE3_A/I datasheet, P6SMB200AHE3_A/I pinout, P6SMB200AHE3_A/I application, or P6SMB200AHE3_A/I equivalent, key selection criteria include clamping voltage margin relative to protected IC's absolute maximum rating, thermal resistance (RθJA = 100 °C/W), AEC-Q101 qualification status, unidirectional polarity with cathode band marking, and 600 W peak pulse power capability under 10/1000 μs waveform.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal bias it presents high impedance (>1 μA leakage at 171 V), but triggers avalanche conduction when transient voltage exceeds 210 V (VBR min), limiting downstream voltage to ≤274 V (VC) during 10/1000 μs surges. Its glass-passivated junction ensures stable breakdown and low incremental surge resistance.
Designed for automated SMT placement, it meets J-STD-020 MSL Level 1 (peak reflow 260 °C), features matte tin-plated leads compliant with JESD 22-B102, and is qualified to AEC-Q101 for automotive use - confirmed by HE3 suffix and _A/I ordering code denoting AEC-Q101-compliant 13" tape-and-reel packaging.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 171 V - Maximum continuous reverse operating voltage before significant leakage; defines upper limit of protected circuit's nominal rail. |
| VBR (Breakdown Voltage) | 190–210 V at 1 mA - Avalanche onset range; ensures reliable triggering above system operating voltage with margin. |
| VC (Clamping Voltage) | 274 V at IPPM = 2.2 A - Peak voltage seen by protected device during standardized 10/1000 μs transient; critical for IC survivability. |
| PPPM (Peak Pulse Power) | 600 W - Surge energy handling capacity per 10/1000 μs waveform; determines protection level against common lightning/inductive spikes. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance on standard 0.2" × 0.2" copper pads; informs derating above 25 °C ambient. |
| TJ max | +150 °C - Maximum junction temperature; enables operation in under-hood automotive or enclosed industrial environments. |
| AEC-Q101 Qualified | Yes - Validated for automotive electronics per stress test requirements; required for ECU, body control, and ADAS subsystems. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with molded UL 94 V-0 compound. Cathode indicated by band on one end; anode is opposite terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected line; conducts surge current to ground when voltage exceeds VBR. |
| Anode | Reference / return path | Typically tied to system ground or low-impedance return; completes clamping path during overvoltage event. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 μs) | Enables robust protection against IEC 61000-4-5 Level 3 (1 kV/2 Ω) surges without derating in compact SMB footprint. |
| Glass passivated junction | Ensures stable, repeatable avalanche characteristics over temperature and lifetime; reduces parameter drift vs. epoxy-passivated alternatives. |
| AEC-Q101 qualified (HE3 suffix) | Validates reliability for automotive applications including engine control, infotainment, and lighting modules per stress test requirements. |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and single-reflow processing at 260 °C peak, simplifying manufacturing and eliminating bake requirements. |
| Matte tin-plated leads | Guarantees solderability per J-STD-002 and whisker resistance per JESD 201 Class 2, supporting long-term field reliability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ200A-E3/5B | Same VWM/VBR/VC ratings; SMA package (smaller footprint, higher RθJA = 140 °C/W); non-AEC-Q101. | Limited to commercial-grade consumer/industrial use; unsuitable for automotive due to lack of qualification and thermal derating margin. | Select when board space is constrained and AEC-Q101 is not required; verify thermal performance at elevated ambient. |
| 1.5SMC200AHE3_A | Same electrical specs; larger SMC (DO-214AB) package (higher power handling, lower RθJA = 60 °C/W); identical AEC-Q101 qualification. | Better thermal performance for high-duty-cycle surges; requires larger PCB area and may impact layout density. | Prefer for high-reliability automotive modules where sustained surge repetition or elevated ambient temperatures exist. |
Compared with SMAJ200A-E3/5B, P6SMB200AHE3_A/I offers superior thermal management and automotive qualification; versus 1.5SMC200AHE3_A, it trades some thermal margin for smaller SMB footprint - ideal for space-constrained ECU modules needing AEC-Q101 compliance.

FAQ
What is the clamping voltage of P6SMB200AHE3_A/I at its rated peak pulse current?
The P6SMB200AHE3_A/I has a maximum clamping voltage (VC) of 274 V at its rated peak pulse current (IPPM) of 2.2 A under the standard 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet (Doc. #88370) and defines the highest voltage the protected circuit will experience during a worst-case transient event. Engineers must ensure this clamping level remains safely below the absolute maximum voltage rating of downstream ICs.
Is P6SMB200AHE3_A/I qualified for automotive applications?
Yes, P6SMB200AHE3_A/I is AEC-Q101 qualified, as confirmed by the "HE3" suffix and ordering code "_A/I", which denotes AEC-Q101-compliant construction and 13" tape-and-reel packaging. It is intended for use in automotive subsystems such as engine control units, body electronics, and ADAS sensors where reliability under temperature cycling, humidity, and mechanical stress is mandatory.
What does the "A" in P6SMB200AHE3_A/I signify?
The "A" in P6SMB200AHE3_A/I indicates unidirectional polarity - meaning the device functions as a single-ended TVS diode with a defined cathode (marked by a band) and anode. This distinguishes it from bidirectional variants (e.g., P6SMB200CA), which suppress transients in both directions and carry a "C" suffix. The "A" also aligns with the series' standard tolerance grade (±5 % on VBR).
How does the SMB package of P6SMB200AHE3_A/I compare thermally to larger packages like SMC?
The SMB (DO-214AA) package of P6SMB200AHE3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W on standard 0.2" × 0.2" copper pads, compared to ~60 °C/W for the larger SMC (DO-214AB) package. This means P6SMB200AHE3_A/I requires more careful thermal design in high-duty-cycle or high-ambient applications, though its AEC-Q101 qualification and compact size make it preferred for dense automotive PCB layouts.
Can P6SMB200AHE3_A/I be used in bidirectional signal line protection?
No, P6SMB200AHE3_A/I is strictly unidirectional and must not be used on bidirectional signal lines such as RS-485 or CAN buses without external circuitry. Its asymmetrical IV curve conducts only in reverse bias above VBR; forward conduction is limited to ~3.5 V at 50 A. For bidirectional protection, select a CA-suffixed variant like P6SMB200CAHE3_A/I, which provides symmetrical clamping in both polarities.
