Product details
Overview
P6SMB300A01HM3_C/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 power and signal lines. It features a 300 V standoff voltage (VWM), 344 V 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 automotive-grade industrial power supplies and sensor interface circuits.
For engineers reviewing the P6SMB300A01HM3_C/I datasheet, P6SMB300A01HM3_C/I pinout, P6SMB300A01HM3_C/I application, or P6SMB300A01HM3_C/I equivalent, key selection criteria include its AEC-Q101 qualification, halogen-free RoHS-compliant HM3 suffix, SMB (DO-214AA) package thermal performance, and verified clamping behavior under repetitive transients per IEC 61000-4-5.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-banded polarity, leveraging glass-passivated junction technology for stable breakdown and low incremental surge resistance. Its 100 °C/W junction-to-ambient thermal resistance (RθJA) and 20 °C/W junction-to-lead (RθJL) support reliable operation up to 150 °C junction temperature under defined PCB pad layout (0.2" × 0.2" copper).
The device meets MSL Level 1 per J-STD-020 with 260 °C reflow peak, and its 0.110 %/°C temperature coefficient of VBR ensures predictable voltage drift across operating range. Designed for automated SMT placement, it delivers fast response time (<1 ns) and excellent clamping ratio (VC/VBR ≈ 1.15) when protecting MOSFETs, ICs, and sensor signal lines against inductive switching and lightning-induced surges.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ300A-E3/5B | Same VWM (300 V), but lower PPPM (400 W); SMA package (smaller footprint, higher RθJA = 140 °C/W) | Limited to lower-energy transients; unsuitable for automotive load-dump where 600 W is required. | Select only if space-constrained and surge energy is ≤400 W; verify thermal margin on 0.1"² pads. |
| 1.5SMC300A | Same VWM/VC specs, but larger SMC (DO-214AB) package; higher IPPM (1.5 A), same PPPM (600 W) | Requires more PCB area; better thermal dissipation (RθJA = 75 °C/W) for high-duty-cycle environments. | Prefer for industrial motor drives with frequent surges; avoid if SMB footprint is mandatory for layout compatibility. |
Compared with P6SMB300A01HM3_C/I, SMAJ300A-E3/5B trades power handling for size, while 1.5SMC300A improves thermal margin at the cost of board space - making P6SMB300A01HM3_C/I the optimal balance of AEC-Q101 compliance, 600 W capability, and SMB footprint for automotive and high-reliability industrial designs.

FAQ
What is the maximum clamping voltage of the P6SMB300A01HM3_C/I under a 10/1000 μs surge?
The P6SMB300A01HM3_C/I has a maximum clamping voltage (VC) of 414 V when subjected to its rated peak pulse current of 1.45 A with a 10/1000 μs waveform. This value is measured per standard test conditions in the Vishay datasheet (Document Number: 88370, Rev. 09-Jan-2024) and defines the upper voltage limit imposed on protected circuitry during transient events. The P6SMB300A01HM3_C/I maintains this clamping performance across its specified operating temperature range.
Is the P6SMB300A01HM3_C/I qualified for automotive applications?
Yes, the P6SMB300A01HM3_C/I is AEC-Q101 qualified, as confirmed by its HM3 suffix and documentation in the Vishay P6SMB series datasheet. The HM3 designation indicates halogen-free, RoHS-compliant construction with full AEC-Q101 stress testing including high-temperature reverse bias, temperature cycling, and unbiased highly accelerated stress testing. This makes the P6SMB300A01HM3_C/I suitable for under-hood and chassis-mounted automotive electronics where reliability under thermal and mechanical stress is critical.
What does the "C/I" suffix mean in P6SMB300A01HM3_C/I?
The "C/I" suffix in P6SMB300A01HM3_C/I specifies packaging and reel configuration: "C" denotes 7-inch diameter plastic tape and reel, and "I" indicates a 3200-unit quantity per reel. This matches Vishay's standard ordering code format for the HM3 variant, where "H" is the package code and "I" corresponds to the 13-inch reel option - though here "I" is used with "C" per documented variant P6SMB250AHM3_D/I and P6SMB300A01HM3_C/I in the datasheet's Ordering Information table.
How does the thermal performance of the P6SMB300A01HM3_C/I compare to larger-package TVS diodes?
The P6SMB300A01HM3_C/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads, which is higher than SMC-packaged alternatives like 1.5SMC300A (RθJA = 75 °C/W) but optimized for its SMB footprint. Its junction-to-lead resistance (RθJL) is 20 °C/W, supporting efficient heat transfer to PCB traces. For continuous power dissipation, the P6SMB300A01HM3_C/I is rated at 5.0 W at TA = 50 °C - sufficient for intermittent surge duty but not sustained DC overload.
Can the P6SMB300A01HM3_C/I be used in bidirectional configurations?
No, the P6SMB300A01HM3_C/I is a unidirectional TVS diode, as indicated by its "A" suffix and absence of "CA" in the part number. Bidirectional variants in the P6SMB family use the "CA" suffix (e.g., P6SMB300CA) and exhibit symmetrical clamping in both polarities. Using the unidirectional P6SMB300A01HM3_C/I in a bidirectional application would result in forward conduction during negative transients, potentially damaging the device or failing to protect the circuit - always match polarity to application topology.
