Product details
Overview
P6SMB16AH from Taiwan Semiconductor is a unidirectional 600W surface-mount transient voltage suppressor (TVS) diode with a standoff voltage of 13.6 V, breakdown voltage range of 15.2–16.8 V, and clamping voltage of 22.5 V at 28 A peak pulse current. It protects automotive and industrial power rails against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the P6SMB16AH datasheet, P6SMB16AH pinout, P6SMB16AH application, or P6SMB16AH equivalent, key selection criteria include its AEC-Q101 qualification, DO-214AA (SMB) package compatibility, 1 μA max reverse leakage at VWM, 1.0 ps response time, and junction temperature rating up to +150°C.
Technical Context
The P6SMB16AH uses a glass-passivated silicon junction optimized for fast transient suppression in 12 V automotive systems. Its unidirectional configuration provides forward conduction only during overvoltage events, with VF = 3.5 V at 50 A per specification for devices ≤91 V.
Thermal performance is defined by RθJC = 10°C/W and RθJA = 55°C/W, supporting operation from –55°C to +150°C. It meets JESD201 Class 2 whisker resistance and J-STD-020 Moisture Sensitivity Level 1.
Key Specifications

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V supply lines in engine control units (ECUs) and body control modules (BCMs) against load dump and alternator transients. IC Role / Device Role: Unidirectional TVS clamp placed between power rail and chassis ground to shunt surge energy away from downstream regulators and microcontrollers. Use Value: Limits transient voltage to ≤22.5 V, preventing latch-up or permanent damage to 3.3 V/5 V logic powered from the same rail. | Use Scenario: Safeguarding analog sensor inputs (e.g., pressure, temperature) in factory automation PLCs exposed to EFT bursts on signal lines. IC Role / Device Role: TVS diode installed across differential or single-ended sensor outputs to clamp fast-rising ESD/EFT spikes before they reach ADC front-ends. Use Value: Maintains signal integrity with <1 µA leakage at 13.6 V, avoiding DC offset errors in precision measurement circuits. |
| LED Lighting Driver Protection | DC Motor Drive Back-EMF Suppression |
Use Scenario: Shielding constant-current LED drivers in automotive headlamps from switching noise and inductive kickback during PWM dimming. IC Role / Device Role: TVS placed across driver output terminals to absorb repetitive 600 W transients generated by MOSFET switching and cable inductance. Use Value: Withstands >1000 surges at rated power (per Fig. 2 derating curve), ensuring multi-year reliability in high-duty-cycle lighting systems. | Use Scenario: Suppressing back-EMF spikes from brushed DC motors in power seats, windows, and HVAC actuators. IC Role / Device Role: Unidirectional TVS connected across motor terminals to clamp negative-going flyback voltage during MOSFET turn-off. Use Value: Clamps to 22.5 V while handling 28 A peak current, preventing gate oxide rupture in half-bridge drivers and reducing electromagnetic emissions. |
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, identical VWM/VBR/VC specs, but not AEC-Q101 qualified | Lacks automotive qualification; suitable for industrial/commercial use only | Select SMBJ16A only if AEC-Q101 is not required and cost optimization is prioritized |
| 1.5SMC16A | DO-214AB (SMC) package - larger footprint and higher thermal mass; otherwise matches electrical specs | Requires PCB layout change due to different pad dimensions and mounting area | Choose 1.5SMC16A when higher thermal dissipation margin is needed and board space allows larger package |
Compared with SMBJ16A and 1.5SMC16A, the P6SMB16AH uniquely combines AEC-Q101 qualification, SMB footprint, and 600 W surge rating - making it the preferred choice for space-constrained automotive modules where qualification and reliability are non-negotiable.

FAQ
What is the maximum clamping voltage of the P6SMB16AH under standard test conditions?
The P6SMB16AH has a maximum clamping voltage (VC) of 22.5 V when subjected to a 10/1000 µs surge waveform at 28 A peak pulse current (IPPM). This value is measured per ANSI/IEEE C62.35 and ensures downstream components see limited overvoltage stress during transient events. The P6SMB16AH maintains this clamping performance across its full operating temperature range.
Is the P6SMB16AH suitable for bidirectional transient protection?
No - the P6SMB16AH is a unidirectional TVS diode, designed for protection of DC power rails where polarity is fixed. For bidirectional applications such as data lines or AC-coupled signals, the P6SMB16CAH variant (with CAH suffix) must be used instead. The P6SMB16AH's cathode band marking and forward voltage spec (3.5 V at 50 A) confirm its unidirectional architecture.
Does the P6SMB16AH meet automotive reliability standards?
Yes - the P6SMB16AH is AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD per JESD22-A114. It also complies with ISO 7637-2 Pulse 1/2a/2b/3a/3b for automotive transient immunity. These qualifications make the P6SMB16AH appropriate for under-hood and cabin ECU applications.
What is the thermal resistance from junction to ambient for the P6SMB16AH?
The P6SMB16AH has a junction-to-ambient thermal resistance (RθJA) of 55°C/W under standard JEDEC test conditions (single device on 1-inch² copper pad). This value assumes no additional heatsinking; actual board-level thermal performance depends on PCB copper area, layer count, and airflow. For sustained surge duty, RθJC = 10°C/W enables direct thermal coupling to metal-core substrates.
How does the P6SMB16AH compare to the P6SMB16H variant?
The P6SMB16AH offers tighter breakdown voltage tolerance (15.2–16.8 V) versus the P6SMB16H (14.4–17.6 V), resulting in more consistent clamping behavior across production lots. Both share identical package, power rating, and AEC-Q101 qualification, but the "A" grade improves VBR uniformity - critical for designs requiring precise overvoltage thresholds. The P6SMB16AH marking code is KZJ.
