Product details
Overview
P6SMB110AH from Taiwan Semiconductor is a unidirectional 600W surface-mount transient voltage suppressor (TVS) diode designed for automotive-grade overvoltage protection in power rails and signal lines. It features a 105–116 V breakdown voltage (VBR), 94.0 V maximum standoff voltage (VWM), 152 V clamping voltage at 4.1 A peak pulse current, and AEC-Q101 qualification for under-hood electronics.
For engineers reviewing the P6SMB110AH datasheet, P6SMB110AH pinout, P6SMB110AH application, or P6SMB110AH equivalent, key selection criteria include its DO-214AA (SMB) package compatibility with automated SMT assembly, low leakage (<1 µA @ 94 V), fast sub-1 ps response time, and ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance for automotive transients.
Technical Context
The P6SMB110AH operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its specified VBR range (105–116 V at 1 mA test current). Its glass-passivated junction ensures stable breakdown characteristics and low leakage across -55°C to +150°C operating temperature.
It delivers 600 W non-repetitive peak pulse power (10/1000 µs waveform), with thermal resistance of 10°C/W (junction-to-case) and 55°C/W (junction-to-ambient), enabling reliable operation in high-temperature automotive environments without forced cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 105 V / 116 V - defines precise overvoltage trip threshold at 1 mA; ensures consistent clamping onset across production lots |
| VWM | 94.0 V - maximum continuous reverse working voltage; sets safe DC operating margin below breakdown |
| VC @ IPPM | 152 V @ 4.1 A - clamping voltage during 10/1000 µs surge; limits protected circuit stress to ≤152 V |
| PPPSM | 600 W - peak pulse power rating; supports robust immunity against ISO 7637-2 automotive load dump and inductive switching events |
| IR @ VWM | <1 µA - ultra-low reverse leakage; minimizes standby power loss and avoids false triggering in high-impedance circuits |
| TJ max | +150 °C - maximum junction temperature; enables placement near hot components (e.g., power MOSFETs, engine control units) |
| Package | DO-214AA (SMB) - industry-standard surface-mount outline; compatible with IPC-7351B footprint and reflow profiles |
Pinout & Package
DO-214AA (SMB) package: molded plastic case with matte tin-plated leads, polarity indicated by cathode band; weight ≈ 0.090 g; meets UL 94V-0 flammability and JESD201 Class 2 whisker resistance requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path); carries surge current during clamping |
| Cathode | Reverse-biased clamping terminal | Connected to protected line (e.g., 12 V rail); initiates avalanche conduction when VREV > VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications per stress test requirements including HTOL, TCT, and ESD; supports PPAP documentation |
| Glass passivated junction | Ensures long-term stability of VBR and low leakage under thermal cycling and humidity exposure |
| ISO 7637-2 compliance | Withstands Pulse 1 (inductive load disconnect), Pulse 2a/2b (switching transients), and Pulse 3a/3b (capacitive coupling) without degradation |
| Moisture sensitivity level 1 | No floor life limitation; can be stored indefinitely before reflow without baking preconditioning |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU RoHS Directive; suitable for green manufacturing and end-of-life recycling |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V/24 V battery-fed ECUs from load dump and alternator transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and ground to clamp surges above 94 V. Use Value: Limits rail voltage to ≤152 V during 600 W transients, preventing damage to downstream regulators and microcontrollers in engine control modules. | Use Scenario: Safeguarding analog sensor inputs (e.g., pressure, temperature) from ESD and cable discharge events. IC Role / Device Role / Timing Role: TVS connected across differential or single-ended signal lines to shunt fast transients before they reach ADC front-end. Use Value: Sub-1 ps response ensures clamping occurs before sensitive input structures are overstressed, preserving signal integrity and measurement accuracy. |
| LED Lighting Driver Protection | Telecom Power Supply Input Protection |
Use Scenario: Shielding constant-current LED drivers from inductive kickback during MOSFET switching. IC Role / Device Role / Timing Role: TVS mounted across driver output terminals to absorb energy from flyback spikes. Use Value: 600 W rating handles repetitive switching surges; 152 V clamping prevents overvoltage failure of LED strings and driver ICs. | Use Scenario: Guarding AC/DC or DC/DC converter inputs against lightning-induced surges on telecom power feeds. IC Role / Device Role / Timing Role: Primary-side TVS on 48 V DC input bus to limit transient amplitude before upstream filtering. Use Value: 94 V VWM provides sufficient margin above nominal 48 V, while 152 V VC ensures downstream converters remain within absolute maximum ratings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110A | Same DO-214AA package; VBR = 122–135 V, VC = 177 V @ 3.4 A; higher clamping voltage | Less effective clamping headroom for 12 V systems; better suited for 24 V+ rails where higher VC is acceptable | Select SMBJ110A only if system design tolerates ≥177 V transient excursions and requires tighter VBR tolerance (±5% vs. ±5.5% for P6SMB110AH) |
| 1.5SMC110A | DO-214AB (SMC) package; larger footprint; VBR = 115–127 V, VC = 177 V @ 3.4 A; 1500 W rating | Requires PCB layout change; used where higher surge energy handling is needed beyond 600 W | Choose 1.5SMC110A only when surge duty cycle or energy level exceeds P6SMB110AH's 600 W capability and board space permits SMC footprint |
Compared with SMBJ110A and 1.5SMC110A, the P6SMB110AH offers optimal balance of compact SMB packaging, low clamping voltage (152 V), and AEC-Q101 qualification-making it the preferred choice for space-constrained, automotive-compliant 12 V/24 V protection where strict voltage limiting is critical.

FAQ
What is the breakdown voltage range of the P6SMB110AH?
The P6SMB110AH has a guaranteed breakdown voltage (VBR) range of 105 V to 116 V at 1 mA test current, measured per ANSI/IEEE C62.35. This tight tolerance ensures predictable clamping onset across temperature and production batches, critical for protecting 24 V automotive systems where overvoltage margins are constrained.
Is the P6SMB110AH suitable for bidirectional transient protection?
No-the P6SMB110AH is a unidirectional TVS diode, intended for DC rail protection with defined anode-cathode polarity. For bidirectional applications (e.g., AC lines or data buses), the P6SMB110AH variant must be replaced with the bipolar P6SMB110CAH, which uses symmetrical breakdown characteristics in both directions and carries the "CAH" suffix.
Does the P6SMB110AH meet automotive reliability standards?
Yes-the P6SMB110AH is AEC-Q101 qualified and tested per stress conditions including high-temperature operating life (HTOL), temperature cycling (TCT), and human-body-model ESD. It also complies with ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b, making it suitable for under-hood and chassis-mounted automotive electronics.
What is the maximum clamping voltage of the P6SMB110AH during a surge event?
The P6SMB110AH clamps to a maximum of 152 V at its rated peak pulse current of 4.1 A (10/1000 µs waveform). This value is guaranteed across temperature and represents the highest voltage seen by downstream circuitry during standardized surge testing-enabling accurate overvoltage margin analysis in safety-critical designs.
Can the P6SMB110AH be used in high-humidity environments?
Yes-the P6SMB110AH features a moisture sensitivity level (MSL) of 1 per J-STD-020, meaning it has no floor life limitation and does not require dry-packaging or baking prior to reflow. Its glass-passivated junction and UL 94V-0 molding compound provide long-term reliability in humid or condensing conditions typical of automotive and outdoor industrial deployments.
