Product details
Overview
P6SMB100AHE3/5B from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 100 V standoff voltage (VWM), 105 V minimum breakdown voltage (VBR), 137 V maximum clamping voltage (VC) at 4.4 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial and automotive electronics.
For engineers reviewing the P6SMB100AHE3/5B datasheet, P6SMB100AHE3/5B pinout, P6SMB100AHE3/5B application, or P6SMB100AHE3/5B equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), polarity marking (cathode band), and real-world protection use cases - all critical for surge immunity validation and board-level ESD/transient design.
Technical Context
This TVS diode operates as a unidirectional clamping device, leveraging an avalanche breakdown mechanism to divert transient energy away from sensitive downstream circuitry. Its glass-passivated junction ensures stable leakage performance and fast response time (<1 ns), while the SMB package supports automated placement and meets J-STD-020 MSL Level 1 reflow requirements up to 260 °C peak.
The device is rated for repetitive 10/1000 μs surges at 0.01% duty cycle and derates linearly above 25 °C ambient per Fig. 2. With 1.0 mA test current (IT), it achieves precise VBR tolerance (±5%), low incremental surge resistance, and a temperature coefficient of 0.106 %/°C - enabling predictable clamping behavior across automotive (-40 to +125 °C operating range) and industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 85.5 V - Maximum continuous reverse voltage before significant leakage; defines safe operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 95.0–105 V at 1.0 mA - Avalanche onset range; ensures reliable triggering during transients without premature conduction |
| VC (Clamping Voltage) | 137 V at 4.4 A IPPM - Peak voltage seen by protected circuit during 10/1000 μs surge; determines stress on downstream components |
| PPPM (Peak Pulse Power) | 600 W - Energy-handling capacity for standardized 10/1000 μs waveform; validates robustness against IEC 61000-4-5 Level 4 surges |
| ID (Reverse Leakage) | 1.0 μA max at VWM - Ultra-low leakage preserves system efficiency and prevents false triggering in high-impedance circuits |
| TJ max | +150 °C - Maximum junction temperature; enables operation in under-hood automotive and high-ambient industrial settings |
| RθJA | 100 °C/W - Thermal resistance from junction to ambient on standard 0.2" × 0.2" copper pads; informs PCB thermal layout requirements |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, matte tin-plated leads, RoHS-compliant and AEC-Q101 qualified (HE3 suffix). Cathode indicated by molded band; anode is unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected line; conducts avalanche current to ground during overvoltage events |
| Anode (unbanded end) | Reference node | Typically tied to ground or low-impedance return path; completes clamping loop for unidirectional operation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control units and ADAS sensor interfaces requiring long-term reliability |
| 600 W peak pulse power | Withstands IEC 61000-4-5 combination wave surges (4 kV/2 Ω) without degradation when properly mounted |
| Glass passivated junction | Ensures stable VBR and low leakage over temperature and lifetime; eliminates risk of junction corrosion in humid environments |
| MSL Level 1 rating | Supports lead-free reflow up to 260 °C peak without moisture-induced popcorning; no baking required pre-assembly |
| Low clamping ratio (VC/VBR ≈ 1.30) | Minimizes overvoltage stress on protected ICs - critical for 3.3 V/5 V logic and automotive microcontrollers |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and inductive switching transients in 12 V/24 V vehicle systems. IC Role / Device Role / Timing Role: Unidirectional TVS placed between signal line and chassis ground to clamp transients before they reach the sensor interface IC.

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), VC (137 V), and PPPM (600 W); SMA package (smaller footprint, higher RθJA = 140 °C/W) | Lower power density handling due to reduced thermal mass; less suitable for sustained surge repetition in industrial controls | Select SMAJ100A-E3/5B only when board space is constrained and thermal management via copper pour is impractical |
| 1.5SMC100A | Same electrical specs but SMC (DO-214AB) package; 20% larger footprint, lower RθJA (85 °C/W), higher IFSM (200 A) | Better thermal performance and surge endurance; not AEC-Q101 qualified - requires additional qualification for automotive use | Choose 1.5SMC100A for non-automotive industrial designs needing enhanced thermal margin and higher single-pulse surge capability |
Compared with P6SMB100AHE3/5B, SMAJ100A-E3/5B trades thermal robustness for miniaturization, while 1.5SMC100A offers superior heat dissipation and surge endurance but lacks automotive qualification - making P6SMB100AHE3/5B the optimal balance of AEC-Q101 compliance, SMB manufacturability, and proven 600 W transient handling.

FAQ
What is the clamping voltage of the P6SMB100AHE3/5B at its rated peak pulse current?
The P6SMB100AHE3/5B has a maximum clamping voltage (VC) of 137 V at 4.4 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured per JEDEC test conditions and represents the highest voltage that will appear across the protected circuit during a defined transient event - a critical parameter for ensuring downstream ICs remain within their absolute maximum ratings. The P6SMB100AHE3/5B maintains this clamping performance across its full operating temperature range.
Is the P6SMB100AHE3/5B qualified for automotive applications?
Yes, the P6SMB100AHE3/5B is AEC-Q101 qualified, as confirmed by the "HE3" suffix and Vishay documentation. This qualification covers stress testing for temperature cycling, humidity bias, mechanical shock, and accelerated life - validating suitability for under-hood and cabin electronics such as body control modules and sensor signal conditioning. The P6SMB100AHE3/5B meets the full AEC-Q101 standard, not just partial or derivative testing.
What does the "5B" in P6SMB100AHE3/5B indicate?
The "5B" suffix denotes the packaging configuration: 13-inch diameter plastic tape and reel, containing 3200 units per reel. This format is optimized for high-volume SMT assembly lines using standard pick-and-place equipment. The "HE3" portion confirms RoHS compliance and AEC-Q101 qualification, while "5B" specifies logistics and handling - distinct from "52" (7-inch reel, 750 units) and unrelated to electrical or thermal specifications. The P6SMB100AHE3/5B is fully compatible with J-STD-002 and JESD 22-B102 solderability standards.
How does the thermal resistance of the P6SMB100AHE3/5B affect PCB layout?
The P6SMB100AHE3/5B 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 junction temperature below 150 °C during repetitive surges, designers must allocate sufficient copper area and consider thermal vias beneath the SMB pads. Reducing pad size or omitting thermal relief increases RθJA, risking premature thermal shutdown or parameter shift - a key constraint reflected in the P6SMB100AHE3/5B's derating curve (Fig. 2).
Can the P6SMB100AHE3/5B be used in bidirectional configurations?
No, the P6SMB100AHE3/5B is a unidirectional TVS diode, as indicated by the "A" suffix (not "CA"). Bidirectional variants such as P6SMB100CA exist but feature symmetric clamping in both polarities and no cathode marking. Using the P6SMB100AHE3/5B in reverse-biased AC applications would result in forward conduction and failure. For bidirectional protection, select the correct CA-suffixed part - the P6SMB100AHE3/5B is strictly intended for DC line-to-ground clamping where polarity is maintained.
