Product details
Overview
P6SMB200AHE3/5B 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), designed to protect power rails and signal lines in industrial power supplies and automotive ECUs against lightning-induced surges and inductive switching transients.
For engineers reviewing the P6SMB200AHE3/5B datasheet, P6SMB200AHE3/5B pinout, P6SMB200AHE3/5B application, or P6SMB200AHE3/5B equivalent, this device offers AEC-Q101 qualification, 600 W peak pulse power handling with 10/1000 μs waveform, low incremental surge resistance, and RoHS-compliant matte tin-plated leads suitable for J-STD-002 soldering.
Technical Context
The P6SMB200AHE3/5B operates as a unidirectional clamping device with cathode-band polarity marking, leveraging a glass-passivated silicon junction for stable avalanche behavior under transient overvoltage events. Its thermal resistance (RθJA = 100 °C/W) and junction temperature limit (TJ max = 150 °C) define its derating envelope above 25 °C ambient.
It delivers 600 W peak pulse power per 10/1000 μs waveform at 0.01 % duty cycle, with clamping performance validated at 2.2 A IPPM and 274 V VC - enabling robust protection of 200 V nominal systems without excessive voltage overshoot during surge events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 171 V - Maximum continuous reverse voltage before significant leakage; defines operating rail margin for 200 V DC systems. |
| VBR (Breakdown) | 190–210 V at 1 mA - Confirmed avalanche initiation range; ensures reliable turn-on before system damage threshold. |
| VC (Clamping) | 274 V at 2.2 A IPPM - Peak voltage seen by protected circuit during 10/1000 μs surge; limits stress on downstream MOSFETs or ICs. |
| PPPM | 600 W - Sustains single 10/1000 μs surge without failure; supports IEC 61000-4-5 Level 4 compliance when properly mounted. |
| ID (Leakage) | 1.0 μA max at VWM - Negligible standby power loss; avoids loading of high-impedance sensor bias networks. |
| TJ max | 150 °C - Enables operation in under-hood automotive environments and enclosed industrial enclosures without forced cooling. |
| Package | SMB (DO-214AA) - Surface-mount footprint (5.59 mm × 3.94 mm) compatible with automated placement and reflow; meets UL 94 V-0. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads; cathode indicated by band on one end. Mounting requires 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal per JEDEC standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference node | Connected to ground or low-voltage return path; forms clamping loop with cathode during positive transients. |
| Cathode | Protected line input | Connected to the 200 V rail or signal line being safeguarded; conducts avalanche current to anode during overvoltage. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD; supports under-hood ECU designs. |
| Glass passivated junction | Ensures stable VBR over lifetime and immunity to moisture-induced parameter drift in humid industrial environments. |
| 600 W 10/1000 μs rating | Withstands repeated surge events up to 0.01 % duty cycle without degradation; eliminates need for external heat sinking. |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles; no floor life limitation or baking required prior to assembly. |
| Low clamping ratio (VC/VBR ≈ 1.34) | Minimizes overvoltage exposure during clamping; critical for protecting 200 V-rated GaN FETs or wide-bandgap power stages. |

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 specs but lower PPPM (400 W); SMA package (smaller footprint, higher RθJA). | Limited to lower-energy surges; unsuitable for IEC 61000-4-5 Level 4 or automotive load dump. | Select only if board space is constrained and surge energy is confirmed ≤400 W. |
| 1.5SMC200AHE3/5B | Same electrical specs but SMC (DO-214AB) package; 20 % larger footprint, lower RθJA (70 °C/W). | Better thermal performance for high-repetition-rate surges; requires more PCB area. | Prefer when sustained surge duty cycles exceed 0.01 % or ambient exceeds 85 °C. |
Compared with SMAJ200A-E3/5B, P6SMB200AHE3/5B delivers 50 % higher surge power headroom and superior thermal margin; versus 1.5SMC200AHE3/5B, it trades 20 % board area for full AEC-Q101 qualification and identical clamping performance in a smaller SMB outline.

FAQ
What is the clamping voltage of the P6SMB200AHE3/5B at its rated peak pulse current?
The P6SMB200AHE3/5B has a maximum clamping voltage (VC) of 274 V at 2.2 A peak pulse current (IPPM) under 10/1000 μs waveform conditions. This value is measured per Figure 1 in Vishay document 88370 and defines the upper voltage limit imposed on protected circuits during standardized surge events. The P6SMB200AHE3/5B maintains this clamping performance across its qualified temperature range and after multiple surge cycles when mounted per recommended pad layout.
Is the P6SMB200AHE3/5B suitable for automotive applications?
Yes, the P6SMB200AHE3/5B is AEC-Q101 qualified (denoted by HE3 suffix and revision code B), making it suitable for automotive applications including engine control units, body control modules, and ADAS power domains. It passes stress tests for temperature cycling, high-temperature reverse bias, and mechanical shock per AEC-Q101 Rev D. The P6SMB200AHE3/5B also meets MSL Level 1 and supports lead-free reflow, fulfilling key manufacturing and reliability requirements for automotive electronics.
What does the "HE3/5B" suffix indicate in P6SMB200AHE3/5B?
The "HE3" suffix denotes RoHS-compliant construction with AEC-Q101 qualification, while "5B" specifies packaging in 13-inch diameter plastic tape and reel containing 3200 units. This differs from "52" (7-inch reel, 750 units) and aligns with high-volume SMT production needs. The P6SMB200AHE3/5B uses matte tin-plated leads compliant with J-STD-002 and JESD22-B102 whisker standards, ensuring solderability and long-term interconnect reliability.
How does the P6SMB200AHE3/5B compare to bidirectional variants like P6SMB200CAHE3/5B?
The P6SMB200AHE3/5B is unidirectional and features a cathode band for polarity identification, whereas P6SMB200CAHE3/5B is bidirectional with no polarity marking and symmetric clamping in both directions. The unidirectional P6SMB200AHE3/5B offers lower leakage (<1 μA at 171 V) and is preferred for DC rail protection, while the bidirectional variant suits AC-coupled signal lines or differential buses. Both share identical VWM, VBR, VC, and PPPM ratings within their respective configurations.
What is the thermal resistance and maximum junction temperature of the P6SMB200AHE3/5B?
The P6SMB200AHE3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads, and a maximum junction temperature (TJ max) of +150 °C. These values define its safe operating area: at 25 °C ambient, it can dissipate 5.0 W continuously, but must be derated linearly above that temperature per Figure 2 in document 88370. The P6SMB200AHE3/5B remains functional up to TJ = 150 °C, supporting use in sealed enclosures or under-hood locations.
