Overview
P6SMB24AHM3/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 24 V standoff voltage (VWM = 20.5 V), 33.2 V clamping voltage at 18.1 A peak pulse current, and 600 W peak pulse power with 10/1000 μs waveform - deployed for overvoltage protection of MOSFETs, ICs, and sensor signal lines in industrial and automotive electronics.
For engineers reviewing the P6SMB24AHM3/I datasheet, P6SMB24AHM3/I pinout, P6SMB24AHM3/I application, or P6SMB24AHM3/I equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), halogen-free RoHS compliance, and real-world clamping behavior under transient surge conditions.
Technical Context
This TVS diode operates as a unidirectional clamping device with a glass-passivated junction, designed to shunt transient energy away from sensitive downstream circuitry during ESD or inductive switching events. Its breakdown voltage (VBR) is specified at 22.8–25.2 V (min/max) with 1 mA test current, and it exhibits a low temperature coefficient of 0.094 %/°C for stable performance across temperature.
The device meets J-STD-020 MSL Level 1 moisture sensitivity and supports reflow soldering up to 260 °C peak. With 100 A IFSM rating and 150 °C maximum junction temperature, it sustains repetitive surge stress when mounted on 5.0 mm × 5.0 mm copper pads per terminal - critical for high-reliability industrial power rail and automotive control unit designs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A-E3/5B | Same VWM (20.5 V), VC = 38.9 V at 15.4 A; lower PPPM (400 W); SMA package (smaller footprint, higher RθJA). | Limited to lower-energy transients; less suitable for automotive load dump where 600 W headroom is required. | Select when board space is constrained and surge energy is ≤400 W; verify thermal margin due to RθJA ≈ 140 °C/W. |
| 1.5SMC24A | Same VWM/VC specs, but SMC package (DO-214AB); higher IFSM (200 A); RθJA = 70 °C/W; no AEC-Q101 option. | Better thermal performance and surge endurance, but lacks automotive qualification and has larger footprint. | Choose for industrial power supplies needing higher surge margin and better heat dissipation; not for AEC-Q101–mandated automotive use. |

FAQ
What is the clamping voltage of P6SMB24AHM3/I at its rated peak pulse current?
The clamping voltage (VC) of P6SMB24AHM3/I is 33.2 V at a peak pulse current (IPPM) of 18.1 A, measured using the standardized 10/1000 μs double-exponential waveform. This value defines the maximum voltage imposed on the protected circuit during surge events and is critical for ensuring downstream components like 36 V-rated transceivers remain within safe operating limits. The P6SMB24AHM3/I maintains this clamping performance across its qualified temperature range.
Is P6SMB24AHM3/I qualified for automotive applications?
Yes, P6SMB24AHM3/I is AEC-Q101 qualified - confirmed by the "HM3" suffix denoting halogen-free, RoHS-compliant, and automotive-grade construction. It has passed stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling, making it suitable for under-hood and body electronics such as BCMs and ADAS sensor interfaces where long-term reliability is essential.
What does the "I" in P6SMB24AHM3/I indicate?
The "I" in P6SMB24AHM3/I specifies the packaging configuration: 13-inch diameter plastic tape and reel, with 3200 units per reel. This format supports high-volume automated pick-and-place assembly and is distinct from the "H" variant (7-inch reel, 750 units). Both share identical electrical and thermal specifications; only the delivery packaging differs.
How does the thermal resistance of P6SMB24AHM3/I affect PCB layout?
P6SMB24AHM3/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 under worst-case 5.0 W steady-state dissipation, designers must ensure adequate copper area and avoid excessive ambient temperature rise. Reducing pad size or adding thermal vias lowers RθJA, directly improving surge survivability during repetitive events.
Can P6SMB24AHM3/I be used in bidirectional configurations?
No, P6SMB24AHM3/I is a unidirectional TVS diode - identified by the "A" suffix and cathode band marking. Bidirectional variants use the "CA" suffix (e.g., P6SMB24CA). Using P6SMB24AHM3/I in bidirectional circuits would result in forward conduction during negative transients, causing failure. For AC or dual-polarity signal line protection, select the CA version or pair unidirectional devices in series opposition.
