Product details
Overview
P6SMB300A01HM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for high-energy surge protection on DC power rails and signal lines. It features a 300 V standoff voltage (VWM), 414 V maximum clamping voltage (VC) at 1.45 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform - deployed in industrial motor drives, telecom power supplies, and automotive ECUs.
For engineers reviewing the P6SMB300A01HM3_A/I datasheet, P6SMB300A01HM3_A/I pinout, P6SMB300A01HM3_A/I application, or P6SMB300A01HM3_A/I equivalent, key selection criteria include clamping voltage margin vs. protected IC's absolute maximum rating, thermal derating above 25 °C, unidirectional polarity marking, and AEC-Q101 qualification status for automotive use cases.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal bias it presents <1 μA reverse leakage at 300 V, then rapidly avalanches when transient voltage exceeds its 315 V max breakdown (VBR) to clamp the line at ≤414 V. Its glass-passivated junction ensures stable avalanche characteristics and low incremental surge resistance.
Mounted on 5.0 mm × 5.0 mm copper pads per terminal, it achieves 100 °C/W junction-to-ambient thermal resistance (RθJA) and supports repetitive 0.01% duty cycle surges. The SMB (DO-214AA) package meets UL 94 V-0 and JESD201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 300 V - Maximum continuous reverse operating voltage before conduction begins; defines safe DC rail operating margin. |
| VBR (Breakdown Voltage) | 285–315 V at 1 mA test current - Confirmed avalanche initiation range; ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | 414 V at 1.45 A IPPM - Peak voltage seen by protected circuit during 10/1000 μs surge; critical for IC overvoltage margining. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capability under standardized 10/1000 μs waveform; enables robust lightning/surge immunity. |
| ID (Reverse Leakage) | 1.0 μA max at 300 V - Minimal standby power loss and signal integrity impact in high-impedance circuits. |
| TJ max | 150 °C - Maximum junction temperature; sets PCB copper pad area and airflow requirements for sustained operation. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD; suffix HM3 denotes halogen-free RoHS + AEC-Q101. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002. Cathode indicated by band; unidirectional polarity only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to system ground or low-side return path; must handle 100 A IFSM surge if used in bidirectional configurations via external circuitry. |
| Cathode | Current exit point during reverse-biased clamping | Connected to protected line (e.g., 24 V rail); band-marked end ensures correct orientation during automated placement. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 μs) | Enables single-device protection against IEC 61000-4-5 Level 4 (4 kV) surges on 24–48 V systems without parallel staging. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (<1 ns response), improving clamping fidelity for sensitive microcontrollers. |
| AEC-Q101 qualified (HM3 suffix) | Validated for automotive under-hood environments including 1000-hr HTOL, -40 °C to +125 °C thermal cycling, and mechanical shock. |
| UL 94 V-0 molding compound | Prevents flame propagation in enclosed enclosures - required for industrial safety certifications (IEC 62368-1, UL 62368). |
| MSL Level 1 (260 °C peak reflow) | Supports standard lead-free SMT assembly without moisture sensitivity concerns or baking requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ300A-E3/5B | Same VWM (300 V), but lower PPPM (400 W); SMA package (DO-214AC), higher RθJA (150 °C/W). | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 without derating. | Select only when board space constraints prohibit SMB footprint or when surge energy is confirmed <400 W. |
| SMCJ300A-M3 | Higher PPPM (1500 W), same VWM (300 V); larger SMC (DO-214AB) package, higher thermal mass. | Overqualified for 600 W needs; requires larger PCB area and may delay response due to higher junction capacitance. | Choose when future-proofing for higher surge standards or when ambient temperature exceeds 85 °C routinely. |
Compared with SMAJ300A-E3/5B and SMCJ300A-M3, P6SMB300A01HM3_A/I delivers optimal balance of 600 W surge handling, AEC-Q101 compliance, and SMB footprint - making it the preferred choice for space-constrained automotive and industrial designs requiring validated reliability without over-engineering.

FAQ
What is the maximum clamping voltage of the P6SMB300A01HM3_A/I under a 10/1000 μs surge?
The P6SMB300A01HM3_A/I has a maximum clamping voltage (VC) of 414 V at 1.45 A peak pulse current (IPPM) under the standardized 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet 88370 and defines the upper voltage limit imposed on protected circuitry during surge events. Designers must ensure this clamping level remains below the absolute maximum rating of downstream components.
Is P6SMB300A01HM3_A/I AEC-Q101 qualified, and what does the "HM3" suffix indicate?
Yes, P6SMB300A01HM3_A/I is AEC-Q101 qualified - confirmed by Vishay's ordering information table noting "_D" suffix for devices ≥250 V and "HM3" denoting halogen-free, RoHS-compliant, and AEC-Q101-qualified construction. The "I" in the full part number specifies 13-inch tape-and-reel packaging (3200 units/reel), while "A01" indicates revision level.
How does the thermal performance of P6SMB300A01HM3_A/I affect PCB layout?
P6SMB300A01HM3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To maintain TJ ≤ 150 °C at full 5.0 W steady-state dissipation, designers must allocate ≥250 mm² total copper area across both terminals and consider airflow or localized heatsinking for ambient temperatures >70 °C.
Can P6SMB300A01HM3_A/I be used in bidirectional protection circuits?
No - P6SMB300A01HM3_A/I is a unidirectional TVS diode, as indicated by the "A" suffix and cathode band marking. For bidirectional protection, Vishay specifies the "CA" suffix (e.g., P6SMB300CA). Using this unidirectional part in AC or floating-line applications risks forward conduction and failure; always verify polarity alignment in schematic and layout.
What is the reverse leakage current specification for P6SMB300A01HM3_A/I at rated standoff voltage?
The P6SMB300A01HM3_A/I exhibits a maximum reverse leakage current (ID) of 1.0 μA at its rated standoff voltage (VWM) of 300 V, measured at TA = 25 °C. This ultra-low leakage preserves power efficiency in battery-backed or high-impedance sensor circuits and ensures minimal loading on precision reference rails.
