Overview
P6SMB100AHE3_B/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 100 V standoff voltage (VWM = 85.5 V), 137 V clamping voltage at 4.4 A peak pulse current (10/1000 μs), and 600 W peak pulse power. It provides robust ESD and surge protection for automotive-grade signal lines and power rails in sensor interfaces and power supply inputs.
For engineers reviewing the P6SMB100AHE3_B/H datasheet, P6SMB100AHE3_B/H pinout, P6SMB100AHE3_B/H application, or P6SMB100AHE3_B/H equivalent, this AEC-Q101 qualified TVS diode delivers verified clamping performance, low leakage (<1 μA at 85.5 V), and MSL Level 1 moisture sensitivity - critical for automotive electronics design, board-level transient immunity validation, and high-reliability industrial power rail protection.
Technical Context
This device operates as a unidirectional avalanche diode, triggering when reverse voltage exceeds its breakdown threshold (VBR min = 95.0 V, max = 105 V at 1 mA). Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns) to transients induced by inductive switching or ESD events.
Designed for surface-mount assembly on standard PCB copper pads (0.2" × 0.2"), it features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and achieves thermal resistance of 100 °C/W (junction-to-ambient) under defined layout conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ100A-E3/5B | Same VWM (85.5 V), identical SMB package, but not AEC-Q101 qualified; lower thermal resistance (RθJA = 85 °C/W). | Targeted at commercial/industrial use only; lacks automotive qualification testing and traceability. | Select when AEC-Q101 is not required and higher thermal efficiency is prioritized in space-constrained designs. |
| 1.5SMC100A | Higher package profile (SMC/DO-214AB), same electrical specs (VWM = 85.5 V, VC = 137 V), 1.5 kW peak power rating. | Used where higher surge margin is needed and PCB real estate allows larger footprint; not suitable for ultra-thin automotive modules. | Choose for legacy industrial systems needing drop-in upgrade path with enhanced energy handling, accepting larger board area. |

FAQ
What is the clamping voltage of the P6SMB100AHE3_B/H at its rated peak pulse current?
The P6SMB100AHE3_B/H has a maximum clamping voltage (VC) of 137 V when subjected to its specified peak pulse current of 4.4 A under the 10/1000 μs waveform condition. This value is measured per JEDEC standards and ensures predictable voltage limiting during surge events. The P6SMB100AHE3_B/H maintains this clamping performance across its operational temperature range and is validated for repeatability in AEC-Q101 stress testing.
Is the P6SMB100AHE3_B/H suitable for automotive applications?
Yes, the P6SMB100AHE3_B/H is explicitly AEC-Q101 qualified, as indicated by the "HE3_B" suffix, and is designed for automotive use cases including sensor interface protection, infotainment power rails, and body control module inputs. The P6SMB100AHE3_B/H undergoes temperature cycling, highly accelerated life testing, and ESD validation per automotive requirements, and its MSL Level 1 rating supports lead-free reflow without preconditioning.
What does the "_B/H" suffix mean in P6SMB100AHE3_B/H?
The "_B" denotes AEC-Q101 qualification for the P6SMB100AHE3_B/H series (covering 6.8 V to 220 V variants), while "/H" specifies packaging in 7" diameter plastic tape and reel with 750 units per reel. This ordering code confirms both automotive-grade reliability and standardized SMT handling - distinct from commercial-grade "E3" or halogen-free "M3" variants without qualification markers.
How does the P6SMB100AHE3_B/H compare to bidirectional TVS diodes like P6SMB100CA?
The P6SMB100AHE3_B/H is unidirectional and intended for DC circuits where polarity is fixed (e.g., 12 V supply lines), offering tighter leakage control and optimized forward conduction behavior. In contrast, P6SMB100CA is bidirectional and suited for AC or floating signal lines. The P6SMB100AHE3_B/H's cathode band marking enables correct orientation during placement, whereas bidirectional types lack polarity markings - a critical distinction affecting schematic symbol usage and PCB layout.
What is the maximum junction temperature rating for the P6SMB100AHE3_B/H?
The P6SMB100AHE3_B/H has a maximum junction temperature (TJ max) rating of +150 °C, enabling operation in under-hood automotive environments and sealed industrial enclosures. This rating is validated per AEC-Q101 thermal stress tests and remains effective when mounted on the recommended 0.2" × 0.2" copper pads. Derating curves in the datasheet confirm usable power dissipation down to ambient temperatures as low as –65 °C.
