Product details
Overview
P6SMB160 from Taiwan Semiconductor is a unidirectional 600W surface-mount transient voltage suppressor (TVS) diode in DO-214AA (SMB) package, with a minimum breakdown voltage of 144 V, maximum clamping voltage of 230 V at 2.7 A peak pulse current, and stand-off voltage of 130 V - designed to protect power supply inputs and DC bus lines against ESD and surge events per ISO 7637-2.
For engineers reviewing the P6SMB160 datasheet, P6SMB160 pinout, P6SMB160 application, or P6SMB160 equivalent, this page delivers verified electrical specs, thermal resistance (RθJA = 55 °C/W), moisture sensitivity level (MSL 1), and real-world use context for automotive-grade transient suppression in SMPS, adapters, and display power rails.
Technical Context
The P6SMB160 operates as a unidirectional avalanche diode, triggering when reverse voltage exceeds its 144–176 V breakdown range (VBR) at 1 mA test current. Its glass-passivated junction ensures stable leakage (<1 µA at 130 V) and fast response (<1.0 ps rise time), enabling effective suppression of fast transients like ISO 7637-2 Pulse 1 (inductive load dump) and Pulse 3b (capacitive coupling).
Thermally, it features RθJC = 10 °C/W and RθJA = 55 °C/W, supporting continuous power dissipation up to 3 W at 25 °C ambient. The device is rated for junction temperatures from –55 °C to +150 °C and meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability standards.
Key Specifications

IC Role / Device Role: Primary-level TVS on main power input to limit bus voltage excursion during 35 V/400 ms load dump events. Use Value: Withstands 600 W peak power and clamps to 230 V - provides ≥2× margin over ISO 7637-2 Pulse 5a limits while maintaining MSL 1 manufacturability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A | Same DO-214AA package; bidirectional variant with symmetric VBR (152–168 V), higher VC (234 V), and identical 600 W rating | Required where AC-coupled or dual-polarity transients exist (e.g., data lines, RS-485); not suitable for DC-only unidirectional rails | Select P6SMB160 for cost-optimized, unidirectional DC bus protection; choose SMBJ160A only if bipolar clamping is mandated by system architecture |
| 1.5SMC160A | Larger DO-214AB (SMC) package; same VBR range (144–176 V), but higher IPPM (3.0 A) and lower VC (220 V); RθJA = 40 °C/W | Better thermal performance and tighter clamping, but requires larger PCB footprint and rework of land pattern | Prefer P6SMB160 for space-constrained SMB layouts; upgrade to 1.5SMC160A only when thermal derating or <220 V clamping is critical |
Compared with SMBJ160A and 1.5SMC160A, the P6SMB160 offers optimal balance of compact DO-214AA footprint, unidirectional efficiency, and automotive-grade ISO 7637-2 compliance - making it ideal for cost-sensitive, high-volume DC power rail protection where polarity is fixed and board area is constrained.

FAQ
What is the breakdown voltage range of the P6SMB160?
The P6SMB160 has a guaranteed breakdown voltage (VBR) range of 144 V to 176 V at 1 mA test current, measured per ANSI/IEEE C62.35. This range ensures reliable avalanche initiation across manufacturing lots and temperature extremes, and is confirmed in TSC's Q2209 datasheet revision for the P6SMB160 device specifically.
Is the P6SMB160 unidirectional or bidirectional?
The P6SMB160 is a unidirectional TVS diode, indicated by the absence of "C" or "CA" suffix. It features a cathode band marking and is intended for DC line protection where polarity is fixed - unlike bidirectional variants (e.g., P6SMB160CA) that suppress transients in both directions.
What is the maximum clamping voltage of the P6SMB160 under surge conditions?
The P6SMB160 clamps to a maximum of 230 V when subjected to its rated 10/1000 µs peak pulse current of 2.7 A. This value is specified in the Electrical Specifications table of the official TSC datasheet and defines the upper voltage limit imposed on protected circuitry during transient events.
Does the P6SMB160 meet automotive surge immunity standards?
Yes, the P6SMB160 meets ISO 7637-2 for automotive transient immunity, covering Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (capacitive coupling). This compliance is explicitly stated in the Features section of the TSC P6SMB6.8(A)–P6SMB220(A) datasheet (Q2209).
What is the thermal resistance of the P6SMB160, and how does it affect PCB layout?
The P6SMB160 has a junction-to-ambient thermal resistance (RθJA) of 55 °C/W. This value assumes standard JEDEC 2-layer board conditions; designers must allocate adequate copper area and thermal vias to maintain junction temperature below 150 °C under sustained 3 W dissipation - especially in enclosed or high-ambient environments where the P6SMB160 is deployed.
