Product details
Overview
P6SMB160AH from Taiwan Semiconductor is a unidirectional 600W surface-mount transient voltage suppressor (TVS) diode with a standoff voltage of 136 V, breakdown voltage range of 152–168 V, and clamping voltage of 219 V at 2.8 A peak pulse current. It features AEC-Q101 qualification, glass passivated junction, and DO-214AA (SMB) package for automotive-grade ESD and surge protection in power rails and signal lines.
For engineers reviewing the P6SMB160AH datasheet, P6SMB160AH pinout, P6SMB160AH application, or P6SMB160AH equivalent, this device is selected for high-reliability transient suppression where low leakage (<1 µA @ 136 V), fast response (<1 ps), and ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance are required in automotive body electronics and industrial control interfaces.
Technical Context
The P6SMB160AH operates as a unidirectional avalanche diode optimized for clamping transients on DC power buses and low-speed signal lines. Its 152–168 V breakdown range ensures stable triggering above system operating voltage while maintaining 136 V standoff to avoid false conduction during normal operation.
Thermal performance is defined by RθJC = 10 °C/W and RθJA = 55 °C/W, supporting sustained 3 W steady-state dissipation at 25 °C ambient. The device meets JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity for robust automated assembly.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A | Same DO-214AA package, identical VWM/VBR/VC specs, but rated for 600 W with tighter VBR tolerance (±5% vs ±5.3% for P6SMB160AH) | No functional difference in clamping behavior; SMBJ160A has broader industry adoption in non-automotive industrial designs | Select SMBJ160A if tighter VBR tolerance is required or if dual-sourcing across multiple suppliers is needed |
| 1.5SMC160A | Larger DO-214AB (SMC) package; same electrical specs but higher thermal mass (RθJA = 40 °C/W vs 55 °C/W) and 1.5 kW peak power rating | Better suited for high-energy, low-duty-cycle surges where PCB space allows larger footprint | Choose 1.5SMC160A only when board layout permits SMC footprint and higher single-pulse energy handling is critical |
Compared with SMBJ160A and 1.5SMC160A, the P6SMB160AH offers AEC-Q101 qualification and J-STD-020 Level 1 moisture sensitivity-making it preferred for automotive production and high-reliability industrial deployments where process robustness and qualification traceability are mandatory.

FAQ
What is the maximum clamping voltage of the P6SMB160AH under standard test conditions?
The P6SMB160AH has a maximum clamping voltage (VC) of 219 V when subjected to its rated peak pulse current of 2.8 A using the 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees that downstream circuitry will not experience voltages exceeding 219 V during a 600 W transient event, making the P6SMB160AH suitable for protecting 136 V-rated systems with safety margin.
Is the P6SMB160AH suitable for bidirectional transient protection?
No, the P6SMB160AH is a unidirectional TVS diode intended for DC line protection with defined anode and cathode terminals. For bidirectional applications, Taiwan Semiconductor specifies the P6SMB160AH variant with "CAH" suffix (e.g., P6SMB160CAH), which provides symmetrical clamping in both polarities. Using P6SMB160AH in AC or bipolar configurations risks failure due to forward conduction during negative transients.
Does the P6SMB160AH meet automotive qualification standards?
Yes, the P6SMB160AH is AEC-Q101 qualified and rated for operation from –55 °C to +150 °C junction temperature. It also complies with JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity-ensuring reliability in reflow assembly and under-hood automotive environments. These qualifications are explicitly documented in the official Taiwan Semiconductor datasheet for P6SMB160AH.
What is the standoff voltage (VWM) of the P6SMB160AH, and why does it matter?
The standoff voltage (VWM) of the P6SMB160AH is 136 V-the maximum DC or continuous reverse voltage the device can withstand without exceeding 1 µA leakage current. This parameter ensures the P6SMB160AH remains non-conductive during normal operation of 120 V or 130 V systems, avoiding power loss or false triggering while still providing robust clamping when transients exceed 152 V (VBR min).
Can the P6SMB160AH be used in place of the P6SMB160H?
Yes, the P6SMB160AH is a tighter-tolerance variant of the P6SMB160H, with breakdown voltage specified as 152–168 V (±5.3%) versus 144–176 V (±11.1%) for P6SMB160H. Both share identical package, power rating, and clamping performance. The P6SMB160AH offers improved consistency for designs requiring tighter VBR control, and the "A" suffix indicates enhanced parameter distribution-making P6SMB160AH a direct upgrade with no layout or schematic changes required.
