Product details
Overview
P6SMB16H from Taiwan Semiconductor is a unidirectional 600W surface-mount transient voltage suppressor (TVS) diode with a breakdown voltage range of 14.4–17.6 V, clamping voltage of 23.5 V at 26 A peak pulse current, and stand-off voltage of 12.9 V. It features glass-passivated junction, AEC-Q101 qualification, and meets ISO 7637-2 Pulse 1/2a/2b/3a/3b for automotive load-dump and EFT immunity.
For engineers reviewing the P6SMB16H datasheet, P6SMB16H pinout, P6SMB16H application, or P6SMB16H equivalent, this device is selected for high-reliability DC power rail protection in automotive ECUs, industrial sensor interfaces, and LED driver input stages where fast clamping (<1.0 ps response), low leakage (<1 µA @ 12.9 V), and robust 600W surge handling are required.
Technical Context
The P6SMB16H operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its minimum breakdown voltage (14.4 V) at 1.0 mA test current. Its clamping action limits transients to ≤23.5 V under 10/1000 µs waveform, enabling protection of downstream 15 V-rated ICs such as CAN transceivers and microcontrollers.
Thermally, it sustains junction temperatures from –55 °C to +150 °C, with RθJC = 10 °C/W and RθJA = 55 °C/W. Its DO-214AA (SMB) package supports automated placement and complies with JESD201 Class 2 whisker resistance and J-STD-020 Moisture Sensitivity Level 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 14.4 V / 17.6 V - Ensures reliable turn-on above 12.9 V system stand-off while avoiding false triggering |
| VWM | 12.9 V - Maximum continuous reverse operating voltage compatible with 13.5 V nominal automotive rails |

Pinout & Package
DO-214AA (SMB) surface-mount package with two terminals: anode and cathode. Cathode identified by molded band. Matte tin-plated leads meet J-STD-002 solderability requirements. Polarity must be observed during PCB layout to ensure correct unidirectional clamping direction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference node for reverse-biased operation | Connected to ground or low-impedance return path; establishes clamping reference for protected line |
| Cathode | Transient voltage input node | Connected to protected line (e.g., 12 V supply rail); conducts avalanche current to anode during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and mechanical shock per stress test plan |
| Glass-passivated junction | Eliminates surface contamination sensitivity and ensures stable VBR over lifetime and humidity exposure |

| ISO 7637-2 compliance | Guarantees survivability against real-world automotive transients including load dump (Pulse 5a/b) and coupled noise (Pulse 1/2a/2b/3a/3b) |
| Moisture Sensitivity Level 1 | Permits unlimited floor life and standard SMT processing without baking preconditioning |
Applications
| Automotive Body Control Module (BCM) | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Protects LIN bus interface and power inputs in BCMs exposed to battery disconnection/load dump events. IC Role / Device Role: Unidirectional TVS placed between 12 V rail and ground to clamp negative transients and limit positive surges. Use Value: Maintains VC ≤23.5 V during 100 V/2 Ω Pulse 2b, preventing latch-up or damage to 24 V-tolerant transceivers and LDOs. |
Use Scenario: Shields 4–20 mA transmitter inputs from EFT bursts induced by nearby motor switching in factory automation. IC Role / Device Role: Front-end transient suppressor on analog input lines feeding precision ADCs and op-amps. Use Value: Sub-µA leakage avoids offset error in µA-level current loops; 23.5 V clamping preserves 24 V system headroom. |
| LED Driver Input Stage | Power-over-Ethernet (PoE) Midspan Injector |
Use Scenario: Safeguards constant-current LED driver ICs from inductive kickback during MOSFET switching in automotive headlamp systems. IC Role / Device Role: Parallel-connected TVS across input capacitor to absorb stored energy from boost inductor flyback. Use Value: 600 W peak power rating handles repetitive 10/1000 µs surges up to 26 A without degradation; DO-214AA fits compact thermal layout. |
Use Scenario: Protects PoE midspan injector DC feed circuitry from lightning-induced surges entering via Ethernet cabling. IC Role / Device Role: Primary-level TVS on 48 V DC output rail prior to isolation transformer and PD interface. Use Value: 12.9 V stand-off enables use on 48 V systems with appropriate series impedance; clamping at 23.5 V prevents overvoltage on downstream DC-DC controllers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A | Same DO-214AA package, bidirectional configuration; VBR = 17.8–19.7 V; VC = 26.0 V @ 23.1 A | Supports AC-coupled or dual-polarity signal lines; not suitable for unidirectional DC rail protection without polarity check | Select SMBJ16A only if bidirectional clamping is required; verify system polarity tolerance before substitution. |
| 1.5SMC16A | Larger DO-214AB (SMC) package; same VBR range (14.4–17.6 V); VC = 24.4 V @ 24.6 A; higher thermal mass | Better power dissipation margin in high-ambient environments; requires larger PCB area and different stencil design | Choose 1.5SMC16A when board space allows and thermal derating above 85 °C ambient is critical. |
Compared with P6SMB16H, SMBJ16A offers bidirectional capability at the cost of higher clamping voltage and reduced DC rail compatibility, while 1.5SMC16A trades smaller footprint for improved thermal performance and layout redesign overhead.

FAQ
What is the maximum clamping voltage of the P6SMB16H under standard test conditions?
The P6SMB16H has a maximum clamping voltage (VC) of 23.5 V when subjected to a 10/1000 µs waveform peak pulse current of 26 A. This value is measured at TA = 25 °C and defines the upper voltage limit imposed on protected circuits during transient events. The P6SMB16H maintains this clamping performance across its full operating temperature range.
Is the P6SMB16H suitable for automotive applications requiring AEC-Q101 qualification?
Yes, the P6SMB16H is explicitly AEC-Q101 qualified per the manufacturer's documentation and testing report A2102. It undergoes stress tests including high-temperature reverse bias, temperature cycling, and mechanical shock, making it suitable for under-hood and body electronics applications. The P6SMB16H meets all requirements for automotive-grade TVS deployment without additional qualification.
Does the P6SMB16H have bidirectional or unidirectional polarity?
The P6SMB16H is a unidirectional TVS diode, indicated by the absence of "C" or "CA" suffix. Its cathode is marked by a band on the DO-214AA package, and it conducts only during reverse-bias overvoltage events. For bidirectional protection, engineers must select variants like P6SMB16CH or P6SMB16CAH, which are electrically symmetrical in both directions.
What is the standoff voltage (VWM) rating for the P6SMB16H, and how does it relate to system voltage?
The P6SMB16H has a maximum working peak reverse voltage (VWM) of 12.9 V, meaning it remains non-conductive below this threshold. This rating aligns with nominal 12 V automotive systems (13.5 V charging), ensuring no leakage or conduction during normal operation while allowing sufficient margin before breakdown at 14.4 V. The P6SMB16H thus provides robust margin against ripple and tolerance drift.
Can the P6SMB16H be used in high-humidity or outdoor industrial environments?
Yes - the P6SMB16H uses glass-passivated junction technology and meets J-STD-020 Moisture Sensitivity Level 1, permitting indefinite exposure to ambient humidity without baking. Its DO-214AA molding compound complies with UL 94V-0 flammability and JEDEC JESD201 Class 2 whisker resistance, supporting long-term reliability in humid, dusty, or thermally cycling industrial deployments. The P6SMB16H is validated for storage and operation from –55 °C to +150 °C.
