Product details
Overview
P6SMB180AH from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode in DO-214AA (SMB) package, with a minimum breakdown voltage of 171 V, maximum clamping voltage of 246 V at 2.5 A peak pulse current, and stand-off voltage of 154 V. It protects automotive and industrial power rails against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the P6SMB180AH datasheet, P6SMB180AH pinout, P6SMB180AH application, or P6SMB180AH equivalent, key selection criteria include clamping performance under 10/1000 µs surge, junction temperature derating above 25°C, unidirectional polarity marking, and AEC-Q101 qualification for automotive use.
Technical Context
The P6SMB180AH employs a glass-passivated silicon junction optimized for fast response (<1.0 ps rise time from 0 V to VBR min) and low leakage (<1 µA at 154 V). Its thermal design supports 150°C max junction temperature with RθJC = 10°C/W and RθJA = 55°C/W, enabling reliable operation in high-ambient environments.
It meets ISO 7637-2 immunity requirements for automotive electronics and complies with JESD201 Class 2 whisker resistance, J-STD-020 Moisture Sensitivity Level 1, RoHS, and halogen-free standards per IEC 61249-2-21.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 171 V / 189 V - ensures reliable triggering above system operating voltage while accommodating manufacturing tolerance |
| VWM | 154 V - maximum continuous reverse working voltage before leakage exceeds 1 µA |
| VC @ IPPM | 246 V at 2.5 A - clamping voltage limits downstream IC stress during 10/1000 µs transients |
| PPPSM | 600 W - peak pulse power rating for non-repetitive 10/1000 µs surges |
| IR @ VWM | <1 µA - minimal leakage preserves battery life and signal integrity in always-on circuits |
| TJ max | +150°C - enables use in under-hood automotive modules and industrial power supplies |
| Package | DO-214AA (SMB) - surface-mount footprint compatible with automated assembly and IPC-7351B standard land patterns |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ180A | Same DO-214AA package, identical VBR range (171–189 V), but lower PPPSM = 600 W and higher VC = 259 V at 2.5 A | Marginally higher clamping reduces protection level for ultra-sensitive 200 V-rated loads | Select when cost sensitivity outweighs 13 V clamping advantage of P6SMB180AH |
| 1.5SMC180A | Higher PPPSM = 1500 W, larger DO-214AB (SMC) package, VC = 259 V at 6.1 A | Requires PCB redesign due to 2.5× larger footprint and different thermal mass | Choose only when system-level surge testing requires >600 W capability and layout allows SMC footprint |
Compared with SMBJ180A and 1.5SMC180A, the P6SMB180AH delivers tighter clamping (246 V vs. 259 V), AEC-Q101 qualification out-of-box, and MSL-1 handling-making it optimal for space-constrained automotive and industrial designs where reliability and manufacturability are prioritized over raw power rating.

FAQ
What is the maximum clamping voltage of the P6SMB180AH under standard test conditions?
The P6SMB180AH has a maximum clamping voltage (VC) of 246 V when subjected to its rated peak pulse current of 2.5 A using the 10/1000 µs waveform. This value is measured at TA = 25°C and defines the upper voltage limit imposed on protected circuitry during transient events. The P6SMB180AH maintains this clamping performance across its specified junction temperature range.
Is the P6SMB180AH suitable for automotive applications?
Yes, the P6SMB180AH is AEC-Q101 qualified and explicitly designed for automotive use. It meets ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b immunity requirements and is rated for operation from –55°C to +150°C. Its glass-passivated junction, MSL-1 rating, and JESD201 Class 2 whisker resistance make the P6SMB180AH appropriate for engine control, body electronics, and ADAS power domains.
How does the P6SMB180AH differ from the P6SMB180H variant?
The P6SMB180AH features a tighter breakdown voltage tolerance (171–189 V) versus P6SMB180H (162–198 V), resulting in more consistent triggering behavior and lower VC (246 V vs. 258 V). Both share the same DO-214AA package, 600 W rating, and AEC-Q101 qualification. The P6SMB180AH is preferred where precise voltage threshold control and minimized clamping overshoot are critical.
What is the reverse leakage current specification for the P6SMB180AH?
The P6SMB180AH specifies maximum reverse leakage current (IR) of less than 1 µA when biased at its stand-off voltage (VWM) of 154 V. This low leakage preserves energy efficiency in battery-backed or always-on systems and prevents false triggering in high-impedance sensing circuits. The P6SMB180AH maintains this spec across its full operating temperature range.
Does the P6SMB180AH have polarity marking, and how is it identified?
Yes, the P6SMB180AH uses a cathode band marking on the DO-214AA (SMB) package to indicate polarity. The banded end is the cathode and must be connected toward the higher-voltage side of the protected line (e.g., 24 V rail), while the unbanded end connects to ground. This unidirectional configuration ensures proper reverse-bias operation during normal conditions and forward conduction only during overvoltage events. The P6SMB180AH's marking code is "NRJ".
