Product details
Overview
P6SMB220AHM3_A/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 220 V standoff voltage (VWM), 231 V minimum breakdown voltage (VBR), and 328 V maximum clamping voltage (VC) at 1.8 A peak pulse current (IPPM), used 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 P6SMB220AHM3_A/H datasheet, P6SMB220AHM3_A/H pinout, P6SMB220AHM3_A/H application, or P6SMB220AHM3_A/H equivalent, this device delivers verified 600 W peak pulse power handling with 10/1000 μs waveform, low incremental surge resistance, and AEC-Q101 qualification - critical for high-reliability overvoltage protection in harsh-environment designs.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, leveraging glass-passivated junction technology for stable avalanche behavior under repetitive transient stress. Its thermal resistance (RθJA = 100 °C/W) and junction temperature limit (TJ max = 150 °C) define safe derating above 25 °C ambient.
The device responds within picoseconds to voltage transients, clamping at ≤328 V when subjected to 1.8 A (10/1000 μs), while maintaining <1.0 μA reverse leakage at 185 V (VWM). It meets J-STD-020 MSL Level 1 and JESD201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 185 V - Maximum continuous reverse operating voltage before clamping initiates |
| VBR (Breakdown Voltage) | 209–231 V at 1 mA test current - Confirmed avalanche onset range for reliable triggering |
| VC (Clamping Voltage) | 328 V at 1.8 A IPPM - Peak voltage seen by protected circuit during worst-case 10/1000 μs surge |
| PPPM (Peak Pulse Power) | 600 W - Sustained transient energy absorption capability per single 10/1000 μs event |
| ID (Reverse Leakage) | ≤1.0 μA at 185 V - Minimal parasitic loading on DC power or signal lines during normal operation |
| TJ max | 150 °C - Maximum junction temperature enabling operation in under-hood automotive or enclosed industrial enclosures |
| Package | SMB (DO-214AA) - Standardized surface-mount footprint compatible with automated assembly and 0.2" × 0.2" copper pad layout |
Pinout & Package
SMB (DO-214AA) package with matte tin-plated leads; cathode identified by molded band on body end. Mounting requires 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal per Vishay recommended layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference node | Connected to ground or return path; defines clamping reference point for unidirectional operation |
| Cathode | High-side transient input | Connected to protected line (e.g., 24 V rail); avalanche conduction occurs from cathode to anode during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness per stress test standards |
| Halogen-free & RoHS-compliant | HM3 suffix confirms compliance with environmental regulations and IPC/JEDEC lead-free soldering profiles up to 260 °C peak |
| 600 W peak pulse power | Enables protection against IEC 61000-4-5 Level 4 (4 kV surge) without cascaded staging in 24 V/48 V systems |
| Low clamping ratio (VC/VBR ≈ 1.42) | Minimizes overvoltage margin between breakdown and clamping, reducing stress on downstream MOSFETs or controllers |
| MSL Level 1 moisture sensitivity | Allows indefinite floor life before reflow; no baking required prior to standard SMT assembly |
Applications
| Industrial Power Supply Protection | Automotive Body Control Module (BCM) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ220A-E3/5B | Same VWM (185 V), identical SMB package, but lower PPPM (400 W) and higher VC (356 V at 1.6 A) | Limited to lower-energy transients; not rated for AEC-Q101 or halogen-free compliance | Select when cost sensitivity outweighs automotive qualification and 600 W surge margin |
| 1.5SMC220AHE3_A | Higher package thermal mass (SMC), same VWM/VC specs, but RθJA = 40 °C/W vs. 100 °C/W - better power dissipation | Requires larger PCB area; suited for high-duty-cycle surge environments where junction heating dominates | Choose for industrial UPS or motor drives needing sustained multi-pulse capability beyond single-event rating |
Compared with SMAJ220A-E3/5B and 1.5SMC220AHE3_A, P6SMB220AHM3_A/H uniquely combines AEC-Q101 qualification, halogen-free construction, and optimized SMB footprint for space-constrained automotive and industrial modules requiring certified reliability without layout redesign.

FAQ
What is the clamping voltage of P6SMB220AHM3_A/H at its rated peak pulse current?
The P6SMB220AHM3_A/H has a maximum clamping voltage (VC) of 328 V when subjected to its specified peak pulse current (IPPM) of 1.8 A under the standard 10/1000 μs waveform. This value is measured per Figure 1 in Vishay Document 88370 and defines the upper voltage limit imposed on protected circuits during surge events. The P6SMB220AHM3_A/H maintains this clamping performance across its qualified operating temperature range.
Is P6SMB220AHM3_A/H suitable for automotive applications?
Yes, P6SMB220AHM3_A/H is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant construction with whisker-resistant terminations. It is explicitly designated for automotive use in Vishay's ordering information table (footnote 1), supporting deployment in body control modules, infotainment power rails, and ADAS sensor interfaces where reliability under thermal and mechanical stress is mandatory. The P6SMB220AHM3_A/H meets all required stress tests per AEC-Q101 Rev D.
What does the "_A/H" suffix mean in P6SMB220AHM3_A/H?
The "_A/H" suffix in P6SMB220AHM3_A/H indicates two distinct ordering attributes: "A" denotes the unidirectional configuration (cathode-banded), and "H" specifies the 7-inch plastic tape-and-reel packaging format with 750 units per reel. This matches Vishay's documented ordering convention in Section 3 of Document 88370, where "H" corresponds to 7" diameter reels and "A" confirms the unidirectional variant - not to be confused with bidirectional "C" suffixes. The P6SMB220AHM3_A/H is therefore a unidirectional TVS supplied on 7" reels.
How does P6SMB220AHM3_A/H compare to P6SMB220AHE3_A/H in terms of compliance?
P6SMB220AHM3_A/H is halogen-free and RoHS-compliant, whereas P6SMB220AHE3_A/H is RoHS-compliant but not halogen-free. Both meet AEC-Q101 qualification and share identical electrical specifications (VWM = 185 V, VC = 328 V), but the HM3 suffix in P6SMB220AHM3_A/H satisfies stricter environmental mandates such as JEDEC JS709E and China RoHS II Annex III. The P6SMB220AHM3_A/H is preferred for export-sensitive or green-certified designs requiring full halogen-free declaration.
What is the maximum operating temperature for P6SMB220AHM3_A/H?
The P6SMB220AHM3_A/H has a maximum junction temperature (TJ max) of +150 °C and an operating junction/storage temperature range of –65 °C to +150 °C. Its thermal resistance junction-to-ambient (RθJA) is 100 °C/W under standard mounting conditions (0.2" × 0.2" copper pads), meaning power dissipation must be derated above 25 °C ambient per Figure 2 in Document 88370. This rating supports use in engine bay or enclosed industrial enclosures where ambient temperatures reach 105 °C, provided board-level thermal design accommodates the derating curve. The P6SMB220AHM3_A/H remains fully functional within this envelope.
