Product details
Overview
P6SMB24AHE3_B/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 24 V standoff voltage (VWM), 25.2 V maximum breakdown voltage (VBR), 33.2 V clamping voltage at 18.1 A peak pulse current, and 600 W peak pulse power capability with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the P6SMB24AHE3_B/H datasheet, P6SMB24AHE3_B/H pinout, P6SMB24AHE3_B/H application, or P6SMB24AHE3_B/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 150 °C max junction temperature, low incremental surge resistance, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a clamping device that remains non-conductive below its 24 V stand-off voltage and rapidly transitions to low-impedance conduction when transient overvoltage exceeds its 22.8–25.2 V breakdown range. Its glass-passivated junction ensures stable leakage performance (<1.0 μA at VWM) and fast response time under ESD or inductive switching events.
The device is rated for 600 W peak pulse power (10/1000 μs), 100 A non-repetitive forward surge current (8.3 ms half-sine), and thermal resistance of 100 °C/W (junction-to-ambient). It meets MSL level 1 per J-STD-020 and is qualified to AEC-Q101 for automotive applications - confirmed by the "HE3" and "_B" suffixes in the part number.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 20.5 V - Maximum reverse working voltage before clamping begins; defines safe operating margin for 24 V nominal systems. |
| VBR (Breakdown) | 22.8–25.2 V at 1.0 mA - Confirmed breakdown threshold range; ensures reliable triggering during transients without premature conduction. |
| VC (Clamping) | 33.2 V at 18.1 A - Maximum voltage seen across protected circuit during 10/1000 μs surge; critical for downstream component voltage rating margin. |
| PPPM | 600 W - Peak pulse power handling with standard 10/1000 μs waveform; supports robust protection against lightning-induced surges and load dump. |
| TJ max | +150 °C - Maximum junction temperature; enables operation in under-hood automotive environments and high-ambient industrial settings. |
| Package | SMB (DO-214AA) - Surface-mount outline with 0.220" × 0.205" footprint; compatible with standard reflow profiles and J-STD-002 solderability requirements. |
| AEC-Q101 | Qualified - Validated for automotive reliability including temperature cycling, HTRB, and ESD; designated by HE3 and _B suffixes. |
Pinout & Package

Key Features
| Feature | Design Value |
|---|---|

| AEC-Q101 qualification | Validates reliability for automotive power modules, body control units, and ADAS sensor power rails. |
| Glass passivated junction | Ensures <1.0 μA reverse leakage at 20.5 V and stable VBR over 1000-hour HTOL stress. |
| Low profile SMB package | 0.086" height allows use in space-constrained PCB layouts while maintaining 100 °C/W thermal resistance. |
| MSL Level 1 rating | Permits unlimited floor life and standard reflow without baking; simplifies SMT manufacturing flow. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A-E3/57T | Same VWM (24 V), lower PPPM (400 W), SMA package (larger RθJA = 120 °C/W) | Limited to lower-energy transients; less suitable for automotive load dump where 600 W is required | Select P6SMB24AHE3_B/H when 600 W surge handling and AEC-Q101 qualification are mandatory. |
| 1.5SMC24A | Same VWM/VBR/VC specs, but SMC package (DO-214AB); higher thermal mass but larger footprint | Better thermal dissipation in high-temperature ambient, but incompatible with dense SMB-layout PCBs | Choose P6SMB24AHE3_B/H for space-constrained automotive modules requiring SMB footprint and AEC-Q101. |
Compared with SMAJ24A-E3/57T and 1.5SMC24A, P6SMB24AHE3_B/H uniquely combines 600 W surge rating, AEC-Q101 qualification, and SMB footprint - enabling drop-in replacement in automotive-grade 24 V systems without layout or thermal redesign.

FAQ
What does the "_B/H" suffix in P6SMB24AHE3_B/H indicate?
The "_B" denotes AEC-Q101 qualification for the P6SMB24AHE3_B/H series, covering voltage grades from 6.8 V to 220 V. The "/H" specifies packaging in 7" diameter plastic tape and reel with 750 units per reel. This suffix combination confirms both automotive reliability validation and standardized SMT delivery format for the P6SMB24AHE3_B/H device.
Is P6SMB24AHE3_B/H unidirectional or bidirectional?
P6SMB24AHE3_B/H is a unidirectional TVS diode, as confirmed by its "A" suffix (per Vishay's naming convention) and the presence of a cathode band marking. It conducts only during reverse-biased overvoltage events - ideal for protecting positive-rail power lines where polarity is fixed. Bidirectional variants use "CA" suffixes (e.g., P6SMB24CA).
What is the maximum clamping voltage of P6SMB24AHE3_B/H and under what test condition?
The maximum clamping voltage of P6SMB24AHE3_B/H is 33.2 V, measured at 18.1 A peak pulse current using the standard 10/1000 μs double-exponential waveform. This value is guaranteed per Vishay's datasheet Table on page 2 and defines the upper voltage limit imposed on protected circuits during surge events.
Does P6SMB24AHE3_B/H meet RoHS and halogen-free requirements?
Yes, P6SMB24AHE3_B/H is RoHS-compliant and halogen-free, as indicated by the "HE3" suffix (RoHS-compliant + AEC-Q101 qualified) and documentation confirming compliance with Vishay's material categorization per doc# 99912. It contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE, and satisfies JEDEC JS709A halogen-free standards.
Can P6SMB24AHE3_B/H be used in place of P6SMB24A-E3/52?
P6SMB24AHE3_B/H can replace P6SMB24A-E3/52 in designs requiring AEC-Q101 qualification and 7" tape-and-reel packaging, as both share identical electrical specs (VWM = 20.5 V, VBR = 22.8–25.2 V, VC = 33.2 V). However, P6SMB24AHE3_B/H adds automotive qualification and uses different reel coding - verify mechanical fit and qualification requirements before substitution in P6SMB24AHE3_B/H applications.
