Product details
Overview
P6SMB180AHM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 180 V standoff voltage (VWM), 246 V maximum clamping voltage (VC) at 2.4 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 µs waveform - deployed to safeguard MOSFETs, ICs, and sensor interfaces in industrial power supplies and automotive control units.
For engineers reviewing the P6SMB180AHM3_A/I datasheet, P6SMB180AHM3_A/I pinout, P6SMB180AHM3_A/I application, or P6SMB180AHM3_A/I equivalent, key selection criteria include verified clamping performance under repetitive surge conditions, AEC-Q101 qualification status, SMB (DO-214AA) package thermal resistance (RθJA = 100 °C/W), and compliance with halogen-free, RoHS-compliant manufacturing standards.
Technical Context
The P6SMB180AHM3_A/I operates as a unidirectional avalanche diode, triggering conduction when reverse voltage exceeds its 180 V stand-off threshold (VWM) and clamping transients to ≤246 V at rated 2.4 A peak pulse current. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1.0 µA at VWM).
Designed for automated SMT assembly on standard PCB copper pads (0.2" × 0.2"), it delivers fast response time (<1.0 ns), low incremental surge resistance, and meets MSL Level 1 per J-STD-020 with peak reflow temperature up to 260 °C - enabling reliable integration into high-volume automotive and industrial modules.

|---|---|
Use Scenario: Protecting 12 V supply rails and LIN bus lines from load dump and inductive switching transients in vehicle door modules and lighting controllers. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and ground to clamp transients above 180 V while remaining non-conductive during normal operation. Use Value: Prevents latch-up or permanent damage to microcontrollers and driver ICs exposed to ISO 7637-2 Pulse 5a (load dump up to 60 V superimposed on 14 V system). | Use Scenario: Shielding 24 V DC digital input channels from field-induced surges caused by relay coil de-energization or lightning-induced coupling in factory automation cabinets. IC Role / Device Role / Timing Role: Standoff-rated TVS connected across input optocoupler terminals to limit transient voltage before isolation barrier. Use Value: Maintains functional safety integrity by ensuring input stage remains within safe operating area during IEC 61000-4-4 EFT bursts (±2 kV) and surge events (±1 kV). |
| Telecom Power Supply Front-End | Consumer Appliance Motor Drive Board |
Use Scenario: Guarding AC/DC converter primary-side bias rails and secondary-side 5 V/3.3 V logic supplies against AC line surges and cross-talk from adjacent switching stages. IC Role / Device Role / Timing Role: Secondary-side TVS on regulated output to suppress reflected transients from downstream DC-DC converters or hot-swap events. Use Value: Enables compliance with EN 61000-4-5 (surge immunity) and avoids brownout resets in baseband processors due to momentary rail collapse. | Use Scenario: Safeguarding gate drive signals and MCU I/O pins connected to BLDC motor phase outputs subject to back-EMF spikes during commutation. IC Role / Device Role / Timing Role: Localized TVS on each half-bridge gate node to clamp inductive kickback before reaching level-shifter or driver inputs. Use Value: Eliminates false triggering and gate oxide stress by limiting transient overshoot to ≤246 V, preserving long-term reliability of 5 V-tolerant logic interfaces. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ180A-E3/5B | Same 180 V VWM and 246 V VC, but SMA package (DO-214AC); RθJA = 140 °C/W vs. 100 °C/W | Limited power derating above 75 °C ambient; less suitable for high-density automotive modules with constrained airflow | Select only if board space requires smaller footprint and thermal margin permits higher junction rise |
| 1.5SMC180AHE3_A | Same electrical specs, but SMC (DO-214AB) package; 1.5 kW rating (10/1000 µs) vs. 600 W; RθJA = 60 °C/W | Higher surge capacity supports repeated surge events in harsh environments like railway signaling | Choose when system-level surge testing exceeds single-event 600 W requirement or extended thermal design life is critical |
Compared with SMAJ180A-E3/5B and 1.5SMC180AHE3_A, the P6SMB180AHM3_A/I offers optimal balance of AEC-Q101 qualification, halogen-free compliance, SMB thermal performance, and cost-effective 600 W surge handling - making it preferred for space-constrained, thermally managed automotive and industrial control boards where full 1.5 kW rating is unnecessary.

FAQ
What is the maximum clamping voltage of the P6SMB180AHM3_A/I under standard test conditions?
The P6SMB180AHM3_A/I has a maximum clamping voltage (VC) of 246 V when subjected to a 10/1000 µs waveform at its rated peak pulse current of 2.4 A. This value is measured per Figure 1 in Vishay document 88370 and defines the upper voltage limit imposed on protected circuitry during transient events. The P6SMB180AHM3_A/I maintains this clamping performance across its specified operating temperature range and is validated for repetitive surge duty cycles up to 0.01 %.
Is the P6SMB180AHM3_A/I qualified for automotive applications?
Yes, the P6SMB180AHM3_A/I is AEC-Q101 qualified, as confirmed by its HM3 suffix and documentation in Vishay's P6SMB series datasheet (Rev. 09-Jan-2024, Doc. #88370). It undergoes stress testing including temperature cycling, high-temperature reverse bias, and ESD per the AEC-Q101 standard. The P6SMB180AHM3_A/I is specifically intended for use in automotive subsystems such as body control modules, infotainment power rails, and sensor interface protection where qualification is mandatory.
What does the "HM3" suffix indicate in P6SMB180AHM3_A/I?
The "HM3" suffix in P6SMB180AHM3_A/I denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. Per Vishay's ordering information table, HM3 indicates compliance with JEDEC J-STD-609A Class 1 and adherence to automotive reliability requirements. The "_A/I" further specifies packaging: 13-inch tape-and-reel format (I) with 3200 units per reel. The P6SMB180AHM3_A/I thus meets both environmental and functional safety mandates for modern automotive electronics.
How does the SMB package of the P6SMB180AHM3_A/I compare thermally to SMA or SMC alternatives?
The SMB (DO-214AA) package of the P6SMB180AHM3_A/I provides a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W on standard 0.2" × 0.2" copper pads - superior to SMA (140 °C/W) but higher than SMC (60 °C/W). This allows the P6SMB180AHM3_A/I to sustain full 600 W surge capability at lower ambient temperatures and supports denser board layouts than SMC. Its thermal profile makes the P6SMB180AHM3_A/I especially well-suited for compact automotive ECUs where airflow is limited but full AEC-Q101 compliance is required.
Can the P6SMB180AHM3_A/I be used in bidirectional configurations?
No, the P6SMB180AHM3_A/I is a unidirectional TVS diode, as indicated by its "A" suffix and cathode band marking. Bidirectional variants in the P6SMB family use the "CA" suffix (e.g., P6SMB180CA). Using the P6SMB180AHM3_A/I in reverse-biased AC applications would result in forward conduction and failure. For bidirectional protection at 180 V, the correct device is P6SMB180CAHM3_A/I - which has symmetric breakdown in both directions and no polarity marking.
