Product details
Overview
P6SMB220AHM3/I 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), designed to protect power rails and signal lines in industrial and automotive electronics against ESD and inductive switching transients.
For engineers reviewing the P6SMB220AHM3/I datasheet, P6SMB220AHM3/I pinout, P6SMB220AHM3/I application, or P6SMB220AHM3/I equivalent, key selection criteria include clamping performance under 10/1000 µs surge, thermal resistance (RθJA = 100 °C/W), AEC-Q101 qualification status, halogen-free RoHS compliance, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
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 and low incremental surge resistance. Its 600 W peak pulse power rating (10/1000 µs waveform, 0.01% duty cycle) is validated under standardized mounting conditions using 5.0 mm × 5.0 mm copper pads per terminal.
Thermal performance is defined by RθJA = 100 °C/W (junction-to-ambient, free-air) and RθJL = 20 °C/W (junction-to-lead), enabling reliable operation up to TJ = +150 °C. The device meets J-STD-020 MSL Level 1 and JESD201 Class 2 whisker resistance requirements, with matte tin-plated leads solderable per J-STD-002 and JESD22-B102.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 185 V - Maximum reverse voltage before significant leakage; defines safe operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 209–231 V at IT = 1 mA - Avalanche onset range; ensures predictable turn-on during transient events |
| VC (Clamping Voltage) | 328 V at IPPM = 1.8 A - Peak voltage seen by protected circuit during 10/1000 µs surge; critical for IC/MOSFET survivability |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capability under standardized surge waveform; enables robust protection in harsh environments |
| ID (Reverse Leakage) | 1.0 µA at VWM = 185 V - Ultra-low leakage preserves system efficiency and minimizes standby power loss |
| TJ max. | +150 °C - Maximum junction temperature; supports operation in under-hood automotive and high-temperature industrial enclosures |
| Package | SMB (DO-214AA) - Low-profile surface-mount outline with 0.220" × 0.130" footprint; optimized for high-density PCB layouts and reflow compatibility |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, unidirectional configuration with cathode band marking. Dimensions: 5.59 mm × 3.30 mm × 2.20 mm (L × W × H); terminals are matte tin-plated for solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; connected to lower-potential side of protected line | Defines polarity-sensitive placement-must be oriented toward ground or return path in unidirectional protection topology |
| Cathode | Current exit point in forward bias; marked with band; connected to higher-potential side (e.g., supply rail) | Ensures correct clamping direction: transient energy shunted from cathode to anode when VC exceeds VWM |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity testing, and mechanical shock per AEC specification |
| Halogen-free & RoHS-compliant | HM3 suffix denotes full compliance with JEDEC JS709E and EU RoHS Directive 2011/65/EU; no brominated flame retardants |
| 600 W peak pulse power (10/1000 µs) | Withstands high-energy transients common in motor drives, solenoid switching, and power supply input stages without degradation |
| Low clamping ratio (VC/VBR ≈ 1.42) | Minimizes overvoltage stress on downstream components-critical for protecting 200 V-rated MOSFETs and gate drivers |
| MSL Level 1, 260 °C peak reflow | Enables single-pass lead-free reflow assembly without moisture-related popcorn failure or delamination |
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 |
|---|---|---|---|
| SMAJ220A-E3/5B | Same VWM (185 V), identical SMB package, but non-AEC-Q101, standard RoHS (not halogen-free), RθJA = 110 °C/W | Limited to commercial/industrial use; not approved for automotive under-hood deployment | Select when AEC-Q101 and halogen-free compliance are not required, and cost sensitivity outweighs automotive qualification needs |
| 1.5SMC220AHE3_A/H | Higher PPPM (1500 W), larger SMC (DO-214AB) package, same VWM/VBR/VC specs, AEC-Q101 qualified, halogen-free | Requires larger PCB area (7.11 mm × 6.22 mm vs. 5.59 mm × 3.30 mm); suited for higher-energy surge environments | Choose when system-level surge testing exceeds IEC 61000-4-5 Level 4 and 600 W is insufficient |
Compared with SMAJ220A-E3/5B, P6SMB220AHM3/I offers automotive qualification and halogen-free construction at identical electrical performance; versus 1.5SMC220AHE3_A/H, it trades 900 W extra surge capacity for 40% smaller footprint and lower thermal resistance in space-constrained modules.

FAQ
What is the maximum clamping voltage of the P6SMB220AHM3/I under a 10/1000 µs surge?
The P6SMB220AHM3/I has a maximum clamping voltage (VC) of 328 V at 1.8 A peak pulse current (IPPM) under the standardized 10/1000 µs waveform. This value is measured with the device mounted on 0.2" × 0.2" copper pads per terminal and represents the upper voltage limit imposed on protected circuitry during surge events. The P6SMB220AHM3/I maintains this clamping performance across its specified operating temperature range.
Is the P6SMB220AHM3/I qualified for automotive applications?
Yes, the P6SMB220AHM3/I is AEC-Q101 qualified, as indicated by the "HM3" suffix and confirmed in Vishay's ordering information table (page 3, footnote 1). It undergoes rigorous stress testing-including temperature cycling, humidity bias, and mechanical shock-to meet automotive reliability standards for under-hood and chassis-mounted electronics. The P6SMB220AHM3/I is explicitly designated for automotive use in Vishay's documentation.
What does the "HM3" suffix signify in P6SMB220AHM3/I?
The "HM3" suffix in P6SMB220AHM3/I denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. "H" indicates halogen-free molding compound per JEDEC JS709E, "M3" confirms RoHS compliance and JESD201 Class 2 whisker resistance, and the absence of "B" or "D" means it belongs to the base P6SMB220A family (not the extended-voltage AEC-Q101 variants). The "I" denotes 13" tape-and-reel packaging (3200 units per reel).
How does the thermal resistance of the P6SMB220AHM3/I affect PCB layout?
The P6SMB220AHM3/I has RθJA = 100 °C/W (junction-to-ambient) and RθJL = 20 °C/W (junction-to-lead), meaning effective heat dissipation relies heavily on copper pad area and airflow. For continuous power handling, Vishay specifies mounting on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. Reducing pad size increases junction temperature, potentially derating surge capability-so PCB layout must strictly follow the recommended pad dimensions to maintain rated PPPM and TJ limits.
Can the P6SMB220AHM3/I be used in bidirectional configurations?
No, the P6SMB220AHM3/I is a unidirectional TVS diode, as confirmed by its part number ending in "A" (not "CA") and the presence of a cathode band marking. Bidirectional variants in the P6SMB series use the "CA" suffix (e.g., P6SMB220CA) and lack polarity markings. Using P6SMB220AHM3/I in bidirectional applications would result in forward conduction during negative transients, causing failure. For bidirectional protection, select P6SMB220CA or equivalent.
