Product details
Overview
P6SMB110A-E3/5B from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 110 V breakdown voltage (VBR = 105–116 V at IT = 1.0 mA), 152 V maximum clamping voltage (VC) at 3.9 A peak pulse current (IPPM), and 600 W peak pulse power (10/1000 μs waveform). It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients and lightning surges in industrial and automotive electronics.
For engineers reviewing the P6SMB110A-E3/5B datasheet, P6SMB110A-E3/5B pinout, P6SMB110A-E3/5B application, or P6SMB110A-E3/5B equivalent, this page delivers verified electrical parameters, thermal derating behavior, RoHS-compliant commercial-grade packaging, and AEC-Q101-qualified alternatives - all critical for ESD/surge protection design validation and BOM selection.
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt protector: under normal bias it presents high impedance (<1.0 μA reverse leakage at 94.0 V stand-off), then rapidly avalanches below 152 V to divert surge energy away from downstream circuitry. Its glass-passivated junction ensures stable breakdown and low incremental surge resistance.
Designed for automated SMT placement on PCBs with 0.2" × 0.2" copper pads per terminal, it meets J-STD-020 MSL Level 1 (260 °C peak reflow) and supports repetitive 0.01% duty-cycle surges. Thermal resistance is 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), enabling reliable operation up to TJ = +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 105 V / 116 V at 1.0 mA test current - defines precise avalanche initiation window for predictable clamping onset |
| VWM | 94.0 V - maximum continuous reverse operating voltage before significant leakage begins |
| VC @ IPPM | 152 V at 3.9 A - clamping voltage during 600 W transient, limiting stress on protected ICs |
| IPPM | 3.9 A (10/1000 μs waveform) - peak surge current capability directly tied to PCB pad thermal mass |
| PPPM | 600 W - standardized surge power rating enabling direct comparison across TVS families |
| RθJA | 100 °C/W - thermal resistance used to calculate junction temperature rise under DC power dissipation |
| TJ max. | +150 °C - maximum allowable junction temperature, supporting extended operation in engine bay or industrial enclosures |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, matte tin-plated leads, UL 94 V-0 molding compound. Cathode indicated by band marking on unidirectional devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Use Scenario: Protecting analog output lines (e.g., 4–20 mA current loops) in engine control units from load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional shunt clamp placed between signal line and chassis ground, responding within <1 ns to suppress >100 V transients. Use Value: Limits voltage seen by op-amp input stage to ≤152 V, preventing latch-up or gate oxide damage in precision signal conditioning circuits. |
Use Scenario: Safeguarding digital input channels on programmable logic controllers exposed to relay coil flyback and motor drive noise. IC Role / Device Role / Timing Role: Standoff device mounted at connector entry point, clamping induced spikes before they reach microcontroller GPIO pins. Use Value: Maintains functional integrity during 600 W surges while drawing <1.0 μA at 94 V, avoiding false triggering or signal degradation in 24 V DC systems. |
| Telecom Line Interface | Consumer Power Adapter Output |
|
Use Scenario: Shielding RS-485 transceiver bus lines in base station equipment from lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: Bidirectional-capable family member (e.g., P6SMB110CA) used in differential pair configuration; P6SMB110A-E3/5B applies to single-ended bias rails. Use Value: Clamps common-mode transients to safe levels while preserving signal integrity up to 10 Mbps due to low junction capacitance (~100 pF typical). |
Use Scenario: Secondary-side overvoltage suppression on 12 V DC output rails of wall-mounted AC/DC adapters for smart home devices. IC Role / Device Role / Timing Role: Unidirectional TVS connected between +12 V and GND, activated only during fault conditions to avoid standby power loss. Use Value: Withstands repeated 600 W surges without parameter shift, ensuring multi-year reliability in consumer-grade power supplies with no active cooling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ110A-E3/5B | Same VBR range (105–116 V), but lower PPPM = 400 W and higher VC = 177 V at 2.6 A | Less robust for high-energy surges; suitable only where IEC 61000-4-5 Level 3 (2 kV) suffices | Select when board space allows larger footprint or when cost optimization outweighs 33% power headroom reduction |
| P6SMB110AHM3/5B | Identical electrical specs, but halogen-free, RoHS-compliant, and AEC-Q101 qualified | Required for automotive OEM designs needing qualification evidence and stricter material compliance | Choose for Tier-1 automotive programs where PPAP documentation and stress test reports are mandatory |
Compared with P6SMB110A-E3/5B, SMAJ110A-E3/5B trades surge capacity for smaller SMB-like footprint, while P6SMB110AHM3/5B adds automotive qualification and halogen-free materials without altering clamping performance - enabling direct substitution where compliance drives selection.

FAQ
What is the maximum clamping voltage of the P6SMB110A-E3/5B under surge conditions?
The P6SMB110A-E3/5B has a maximum clamping voltage (VC) of 152 V at its rated peak pulse current of 3.9 A (10/1000 μs waveform). This value is measured under standardized test conditions with 0.2" × 0.2" copper pads per terminal and represents the upper limit of voltage imposed on protected circuitry during a full-power transient event. The P6SMB110A-E3/5B maintains this clamping performance across its specified operating temperature range.
Is the P6SMB110A-E3/5B suitable for automotive applications?
The P6SMB110A-E3/5B is RoHS-compliant and rated for commercial temperature range (−65 °C to +150 °C), but it is not AEC-Q101 qualified. For automotive use, Vishay offers the P6SMB110AHM3/5B variant - identical electrically but certified to AEC-Q101 and halogen-free. The P6SMB110A-E3/5B may be used in non-safety-critical aftermarket or industrial-adjacent automotive subsystems where formal qualification is not mandated.
How does the P6SMB110A-E3/5B differ from bidirectional variants like P6SMB110CA?
The P6SMB110A-E3/5B is unidirectional, with polarity marked by a cathode band and designed for DC-biased lines where reverse conduction must be blocked. In contrast, P6SMB110CA is bidirectional, symmetric in both directions, and used in AC or differential signal paths. Their VBR, VC, and PPPM values are identical, but the P6SMB110A-E3/5B cannot replace P6SMB110CA in AC-coupled applications without circuit redesign.
What is the thermal resistance and how does it affect PCB layout for the P6SMB110A-E3/5B?
The P6SMB110A-E3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead (RθJL) of 20 °C/W. To maintain safe junction temperatures under sustained power dissipation, PCB layout must follow Vishay's recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pad per terminal. Reducing pad size increases RθJA, risking thermal runaway during repetitive surges - a key design constraint for the P6SMB110A-E3/5B.
Does the P6SMB110A-E3/5B require derating at elevated ambient temperatures?
Yes, the P6SMB110A-E3/5B requires derating above TA = 25 °C per Figure 2 in the datasheet: peak pulse power decreases linearly to zero at +150 °C. At 85 °C ambient, the 600 W rating drops to approximately 420 W. This derating is essential for reliable operation in enclosed industrial enclosures or under-hood automotive locations, and must be applied when calculating worst-case surge margin for the P6SMB110A-E3/5B.
