Product details
Overview
P6SMB160H from Taiwan Semiconductor is a unidirectional 600W surface-mount transient voltage suppressor (TVS) diode with a breakdown voltage range of 144–176 V, stand-off voltage of 130.0 V, and clamping voltage of 230 V at 2.7 A peak pulse current. 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 P6SMB160H datasheet, P6SMB160H pinout, P6SMB160H application, or P6SMB160H equivalent, this device is selected for high-energy transient protection in 12 V/24 V automotive power rails, industrial DC supplies, and lighting control circuits where low leakage (<1 µA @ 130 V), fast response (<1.0 ps), and DO-214AA package compatibility are critical.
Technical Context
The P6SMB160H operates as a unidirectional avalanche diode, conducting only in reverse bias above its specified VBR (144–176 V), with clamping action limiting transient voltages to ≤230 V under 10/1000 µs surge conditions. Its thermal resistance RθJA is 55 °C/W, enabling reliable operation up to TJ = 150 °C.
Designed for automotive-grade reliability, it complies with AEC-Q101 stress testing and moisture sensitivity level 1 (J-STD-020). The device exhibits <1 µA reverse leakage at 130 V and a temperature coefficient of VBR of 0.108 %/°C - critical for stable clamping across ambient temperatures from –55 °C to +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 144 V / 176 V - defines minimum and maximum voltage at which avalanche conduction begins under 1 mA test current; ensures consistent clamping threshold across production lot |
| VWM | 130.0 V - maximum continuous reverse operating voltage; must exceed system nominal DC rail (e.g., 24 V automotive) with safety margin |
| VC @ IPPM | 230 V at 2.7 A - clamped voltage during 10/1000 µs surge; determines protected circuit's maximum transient exposure |
| PPPSM | 600 W - non-repetitive peak pulse power rating; supports high-energy transients like ISO 7637-2 Pulse 5a (load dump) |
| IR @ VWM | <1 µA - ultra-low reverse leakage ensures minimal power loss and no interference with high-impedance sensing nodes |
| TJ max | +150 °C - junction temperature limit; enables use in under-hood automotive environments without derating at full power |
| Package | DO-214AA (SMB) - standardized surface-mount outline with 0.090 g mass, matte tin-plated leads, and UL 94V-0 molding compound |
Pinout & Package
DO-214AA (SMB) package: molded plastic case with cathode band marking; polarity-sensitive unidirectional configuration; terminals are anode and cathode, with cathode identified by band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lowest potential node; completes conduction path during reverse transient |
| Cathode | High-side transient input terminal | Connected to protected line (e.g., battery rail); carries surge current into anode during clamping event |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood applications including temperature cycling, humidity bias, and mechanical shock per JESD22 standards |
| Glass-passivated junction | Enhances long-term reliability and stability of VBR under repeated surge stress and high-humidity environments |
| ISO 7637-2 compliance | Withstands Pulse 1 (inductive switch-off), Pulse 2a/2b (battery disconnect), and Pulse 3a/3b (EFT) without degradation |
| Moisture sensitivity level 1 | Zero floor-life limitation - can be mounted directly from tape-and-reel without baking or dry-pack handling |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for environmentally constrained supply chains |
Applications

IC Role / Device Role / Timing Role: Standoff protector on main DC bus before bulk capacitor and DC-DC converter stage. Use Value: Absorbs 600 W peak pulses with <1.0 ps response, ensuring upstream protection does not compromise system startup timing or cause false resets. |
| LED Driver Transient Suppression | Telecom Power Interface |
|

IC Role / Device Role / Timing Role: Parallel-connected TVS across driver output terminals to clamp flyback spikes during PWM dimming transitions. Use Value: Limits voltage overshoot to 230 V with 2.7 A peak current capability, preserving MOSFET gate oxide integrity and avoiding current-sense amplifier saturation. |
Use Scenario: Front-end protection for PoE-powered network switches exposed to lightning-induced surges on 48 V DC input lines. IC Role / Device Role / Timing Role: Primary-level TVS on DC input before hot-swap controller and DC-DC stage. Use Value: Provides 600 W surge rating and 130 V stand-off to coexist with upstream fuse and MOV coordination without premature triggering. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A | Bidirectional variant (±160 V VBR); same DO-214AA package; 1.0 µA leakage @ VWM; 230 V clamping at 2.7 A | Required where bidirectional transients (e.g., AC-coupled signals or floating grounds) exist; not suitable for polarity-sensitive DC rails | Select SMBJ160A only if system design requires symmetrical clamping in both polarities; otherwise P6SMB160H offers lower leakage and tighter VBR tolerance |
| 1.5SMC160A | Higher power (1500 W); larger DO-214AB (SMC) package; 130 V VWM; 259 V clamping at 5.8 A | Used in higher-energy environments (e.g., heavy-duty truck 24 V systems) where 600 W is insufficient | Choose 1.5SMC160A when surge energy exceeds 600 W rating; note PCB footprint change and thermal management impact due to larger package |
Compared with SMBJ160A and 1.5SMC160A, the P6SMB160H delivers optimal balance of compact DO-214AA footprint, ultra-low leakage, and AEC-Q101 validation - making it preferred for space-constrained, automotive-qualified 24 V DC applications where unidirectional protection suffices.

FAQ
What is the breakdown voltage range of the P6SMB160H?
The P6SMB160H has a specified breakdown voltage (VBR) range of 144 V to 176 V at 1.0 mA test current, measured per ANSI/IEEE C62.35. This range reflects production tolerance and ensures reliable clamping initiation across all units. The P6SMB160H is tested to guarantee VBR remains within these limits under standard conditions.
Is the P6SMB160H suitable for automotive applications?
Yes, the P6SMB160H 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 and body electronics. Its DO-214AA package, moisture sensitivity level 1, and –55 °C to +150 °C operating range align with automotive environmental demands. The P6SMB160H is explicitly validated for under-hood deployment.
What is the clamping voltage of the P6SMB160H under surge conditions?
The P6SMB160H clamps to a maximum of 230 V when subjected to a 10/1000 µs waveform peak pulse current of 2.7 A. This value is guaranteed per datasheet specifications and defines the upper voltage limit imposed on protected circuitry during transient events. The P6SMB160H maintains this clamping performance across its full operating temperature range.
Does the P6SMB160H have polarity markings, and how is it oriented in-circuit?
Yes, the P6SMB160H uses a DO-214AA (SMB) package with a cathode band marking on the body. The banded end is the cathode and must be connected to the protected line (e.g., battery rail), while the anode connects to ground or return. This unidirectional orientation ensures proper conduction only during reverse-biased transients. The P6SMB160H is not interchangeable with bidirectional variants without circuit redesign.
What is the maximum steady-state power dissipation of the P6SMB160H?
The P6SMB160H has a steady-state power dissipation (Ptot) rating of 3 W at 25 °C ambient temperature. This rating applies only to continuous DC or low-frequency reverse-bias conditions - not surge events. Thermal derating is required above 25 °C per the datasheet's pulse derating curve. The P6SMB160H relies on its 600 W peak pulse rating for transient suppression, not sustained power handling.
