Product details
Overview
P6SMB180H from Taiwan Semiconductor is a unidirectional 600W surface-mount transient voltage suppressor (TVS) diode with a standoff voltage of 146 V, breakdown voltage range of 162–198 V, and clamping voltage of 258 V at 2.4 A peak pulse current. It features glass-passivated junction, AEC-Q101 qualification, and DO-214AA (SMB) packaging for automotive and industrial power rail protection.
For engineers reviewing the P6SMB180H datasheet, P6SMB180H pinout, P6SMB180H application, or P6SMB180H equivalent, this device is selected for high-energy surge immunity in 12/24/48 V DC systems where low leakage (<1 µA), fast sub-1 ps response, and ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance are required.
Technical Context
The P6SMB180H operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its minimum breakdown voltage (162 V). Its clamping action limits transient-induced overvoltage to ≤258 V under 10/1000 µs waveform, enabling robust protection of downstream MOSFETs, controllers, and sensors.
Thermal performance is defined by RθJC = 10 °C/W and RθJA = 55 °C/W, supporting continuous operation up to TJ = 150 °C. The device meets JESD201 Class 2 whisker resistance and J-STD-020 Moisture Sensitivity Level 1, ensuring reliability in automated SMT assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 146 V - Maximum continuous reverse operating voltage before leakage exceeds 1 µA; sets upper limit for protected circuit's nominal DC rail. |
| VBR (min/max) | 162–198 V - Breakdown voltage range at 1 mA test current; defines threshold for reliable avalanche conduction during transients. |
| VC @ IPPM | 258 V at 2.4 A - Clamped voltage under 10/1000 µs surge; determines worst-case overvoltage seen by protected ICs. |
| PPPSM | 600 W - Peak pulse power rating per 10/1000 µs waveform; quantifies single-event surge energy handling capability. |
| IR @ VWM | <1 µA - Reverse leakage at 146 V; ensures minimal standby power loss and signal integrity in high-impedance nodes. |
| TJ max | 150 °C - Maximum junction temperature; enables use in under-hood automotive environments and enclosed industrial enclosures. |

Applications
| Automotive Power Rail Protection | Industrial PLC Input Protection |
|---|---|
Use Scenario: Protecting 48 V DC power distribution networks in ADAS ECUs against load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and chassis ground to clamp surges before they reach PMICs and microcontrollers. Use Value: Limits transient overvoltage to ≤258 V while maintaining <1 µA leakage at 146 V nominal, preserving system efficiency and meeting OEM EMC requirements. | Use Scenario: Safeguarding digital input channels on programmable logic controllers exposed to inductive switching noise from solenoids and contactors. IC Role / Device Role / Timing Role: Front-end transient suppressor on 24 V opto-isolated inputs to prevent false triggering and latch-up in interface ICs. Use Value: Sub-1 ps response ensures clamping occurs within first nanosecond of surge onset, preventing data corruption in real-time control loops. |
| LED Driver Overvoltage Suppression | Telecom DC Power Interface |
Use Scenario: Shielding constant-current LED driver ICs from flyback spikes generated by magnetic ballasts or relay coils in streetlight systems. IC Role / Device Role / Timing Role: Parallel-connected TVS across driver output terminals to absorb inductive kickback energy without affecting steady-state regulation. Use Value: 600 W peak power rating handles repetitive 10/1000 µs surges common in outdoor lighting environments with minimal derating up to 125 °C ambient. | Use Scenario: Protecting PoE-powered equipment front-ends from lightning-induced surges entering via 48 V DC input ports. IC Role / Device Role / Timing Role: Primary-level TVS on DC input stage upstream of DC-DC converters and hot-swap controllers. Use Value: Clamping voltage of 258 V stays below absolute maximum ratings of common 36 V–60 V input DC-DC ICs, enabling direct integration without additional voltage margining. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ180A | Same DO-214AA package, bidirectional variant with symmetric ±180 V VBR; higher VC = 288 V at same IPPM. | Required where AC-coupled signals or dual-polarity transients (e.g., RS-485 lines) need suppression. | Select SMBJ180A only if bidirectional clamping is explicitly needed; P6SMB180H offers lower clamping voltage for unidirectional DC rails. |
| 1.5SMC180A | Larger DO-214AB (SMC) package; identical electrical specs but 2.5× higher thermal mass and 50% larger PCB footprint. | Suitable when board layout allows larger footprint and higher thermal inertia is beneficial for repetitive surge duty cycles. | Choose 1.5SMC180A only when enhanced thermal dissipation justifies increased board area; P6SMB180H provides optimal density for space-constrained designs. |
Compared with SMBJ180A and 1.5SMC180A, the P6SMB180H delivers the lowest clamping voltage (258 V) in the smallest standard SMB footprint, making it preferred for high-density automotive and industrial DC power protection where layout area and voltage margin are critical.

FAQ
What is the maximum clamping voltage of the P6SMB180H under standard test conditions?
The P6SMB180H has a maximum clamping voltage (VC) of 258 V when subjected to a 10/1000 µs surge waveform at IPPM = 2.4 A. This value is measured per ANSI/IEEE C62.35 and represents the peak voltage seen across the device during worst-case transient events, directly defining the overvoltage stress imposed on downstream components in the protected circuit.
Is the P6SMB180H suitable for automotive applications?
Yes, the P6SMB180H is AEC-Q101 qualified and meets ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b requirements, making it suitable for automotive power rail protection including engine control units, body control modules, and ADAS domain controllers. Its DO-214AA package supports automated placement, and its 150 °C maximum junction temperature accommodates under-hood thermal environments.
Does the P6SMB180H have bidirectional capability?
No, the P6SMB180H is a unidirectional TVS diode intended for DC line protection with cathode connected to the protected rail. For bidirectional applications such as AC signal lines or differential buses, the P6SMB180AH variant (with "AH" suffix) must be used, which provides symmetrical breakdown in both polarities.
What is the standoff voltage rating of the P6SMB180H?
The P6SMB180H has a maximum working peak reverse voltage (VWM) of 146 V, meaning it can continuously block up to 146 V in reverse bias while maintaining reverse leakage below 1 µA. This rating ensures compatibility with 120 V DC nominal systems and provides sufficient margin above typical 48 V or 72 V battery architectures.
How does the P6SMB180H compare to the P6SMB180AH variant?
The P6SMB180H is unidirectional with VBR = 162–198 V and VWM = 146 V, while the P6SMB180AH is bidirectional with symmetric VBR = ±162–198 V and VWM = ±146 V. Both share identical power rating (600 W), clamping voltage (258 V), and package (DO-214AA), but the AH version supports AC-coupled or floating-line protection where polarity reversal may occur.
