Product details
Overview
P6SMB160AHM3_A/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 160 V standoff voltage (VWM), 168 V minimum breakdown voltage (VBR), and 219 V maximum clamping voltage (VC) at 2.7 A peak pulse current (IPPM), designed to protect MOSFETs, ICs, and sensor signal lines against inductive switching transients and ESD in industrial and automotive power electronics.
For engineers reviewing the P6SMB160AHM3_A/H datasheet, P6SMB160AHM3_A/H pinout, P6SMB160AHM3_A/H application, or P6SMB160AHM3_A/H equivalent, key selection criteria include clamping performance under 10/1000 μs surge, AEC-Q101 qualification status, halogen-free RoHS compliance, thermal resistance (RθJA = 100 °C/W), and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, leveraging glass-passivated junction technology for stable surge response and low incremental surge resistance. It delivers 600 W peak pulse power (10/1000 μs waveform) at TA = 25 °C and derates linearly above 25 °C per Fig. 2 in the datasheet.
Designed for transient suppression in DC power rails and low-speed signal paths, it exhibits fast response time (<1 ns), 1.0 μA max reverse leakage at VWM, and meets J-STD-020 MSL Level 1 (260 °C peak reflow). Its 150 °C max junction temperature supports operation in under-hood automotive environments when properly mounted.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 136 V - Maximum continuous reverse operating voltage before clamping initiates; defines safe DC bias margin. |
| VBR (Breakdown Voltage) | 152–168 V at IT = 1.0 mA - Voltage at which device enters avalanche conduction; ensures predictable turn-on threshold. |
| VC (Clamping Voltage) | 219 V at IPPM = 2.7 A - Maximum voltage seen by protected circuit during 10/1000 μs surge; determines stress on downstream components. |
| PPPM (Peak Pulse Power) | 600 W - Surge energy handling capability under standardized 10/1000 μs waveform; validates robustness against lightning/inductive spikes. |
| ID (Reverse Leakage) | 1.0 μA max at VWM - Low leakage preserves system efficiency and prevents false triggering in high-impedance circuits. |
| TJ max | 150 °C - Maximum junction temperature; enables use in engine-control units and industrial motor drives with thermal design margin. |
| RθJA | 100 °C/W - Thermal resistance from junction to ambient; informs PCB copper pad sizing (0.2" × 0.2") for reliable power dissipation. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, halogen-free, RoHS-compliant, matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Cathode identified by band marking; anode is unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected line; conducts surge current to ground when V > VBR. |
| Anode (unbanded end) | Reference node | Typically tied to system ground or lower-potential rail; completes clamping path. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and surge endurance per JESD47. |
| 600 W peak pulse power (10/1000 μs) | Withstands repetitive 0.01% duty-cycle surges without degradation-critical for motor drive gate driver protection. |
| Glass passivated chip junction | Ensures stable VBR over lifetime and immunity to humidity-induced parameter drift in harsh environments. |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without pre-baking; supports high-yield SMT assembly. |
| Low clamping ratio (VC/VBR ≈ 1.35) | Minimizes overvoltage stress on protected ICs-e.g., keeps microcontroller I/O pins below absolute maximum ratings during transients. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ160A-E3/52 | Same VWM (136 V), VC = 221 V at 2.6 A, non-AEC-Q101, RoHS-compliant but not halogen-free. | Lacks automotive qualification and halogen-free certification; suitable for commercial-grade power supplies only. | Select when AEC-Q101 and halogen-free requirements are absent and cost sensitivity outweighs qualification needs. |
| 1.5SMC160AHE3_A | Same VWM/VC specs, but in larger SMC (DO-214AB) package (RθJA = 50 °C/W); AEC-Q101 qualified and halogen-free. | Requires more PCB area and higher thermal mass; better suited for high-reliability 1 kW+ inverters needing lower thermal resistance. | Choose when board layout permits larger footprint and junction temperature margin must exceed 10 °C under sustained surge conditions. |
Compared with SMAJ160A-E3/52 and 1.5SMC160AHE3_A, P6SMB160AHM3_A/H uniquely balances AEC-Q101 compliance, halogen-free construction, and compact SMB footprint-making it optimal for space-constrained automotive and industrial modules where both qualification and miniaturization are mandatory.

FAQ
What is the clamping voltage of P6SMB160AHM3_A/H at its rated peak pulse current?
The P6SMB160AHM3_A/H has a maximum clamping voltage (VC) of 219 V at 2.7 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet 88370 and defines the upper voltage limit imposed on protected circuitry during transient events. The P6SMB160AHM3_A/H maintains this clamping performance across its specified operating temperature range when mounted per recommended pad layout.
Is P6SMB160AHM3_A/H qualified for automotive applications?
Yes, P6SMB160AHM3_A/H is AEC-Q101 qualified, as indicated by the "HM3" suffix and confirmed in the Vishay ordering information table (page 3, footnote 1). It undergoes stress testing for temperature cycling, high-temperature reverse bias, and surge endurance per JESD47. The P6SMB160AHM3_A/H is designated for under-hood and chassis-mounted automotive electronics where reliability under thermal and electrical stress is critical.
What does the "HM3" suffix signify in P6SMB160AHM3_A/H?
The "HM3" suffix in P6SMB160AHM3_A/H denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. Per Vishay's mechanical data section, HM3 parts use molding compounds and plating that meet JESD201 Class 2 whisker resistance and UL 94 V-0 flammability standards. The P6SMB160AHM3_A/H is supplied in 7" tape-and-reel (H) packaging, with "A" indicating revision level and "/H" specifying reel size.
How does the thermal resistance of P6SMB160AHM3_A/H affect PCB layout?
P6SMB160AHM3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To maintain TJ ≤ 150 °C under 5.0 W steady-state dissipation, designers must allocate sufficient copper area and avoid thermal bottlenecks. The P6SMB160AHM3_A/H datasheet specifies exact pad dimensions on page 5 to ensure compliance with this RθJA rating.
Can P6SMB160AHM3_A/H be used in bidirectional configurations?
No, P6SMB160AHM3_A/H is a unidirectional TVS diode, as confirmed by its part number structure (no "C" suffix) and electrical characteristics table listing only unidirectional parameters (VWM, VBR, VC). Bidirectional variants in the P6SMB series use "CA" suffixes (e.g., P6SMB160CA). Using P6SMB160AHM3_A/H in reverse-biased AC applications would result in forward conduction and potential failure; the P6SMB160AHM3_A/H must be oriented with cathode toward the protected line.
