Product details
Overview
P6SMB160AHM3/I 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 600 W peak pulse power (10/1000 μs). It provides clamping at 219 V under 2.7 A peak pulse current and is halogen-free, RoHS-compliant, and AEC-Q101 qualified for automotive-grade surge protection on power rails and signal lines.
For engineers reviewing the P6SMB160AHM3/I datasheet, P6SMB160AHM3/I pinout, P6SMB160AHM3/I application, or P6SMB160AHM3/I equivalent, this device is selected for high-reliability transient suppression where stable clamping voltage, low leakage (<1.0 μA at 136 V), and automotive qualification are required - especially in 12 V/24 V vehicle subsystems, industrial power supplies, and sensor interface protection.
Technical Context
This TVS operates as a unidirectional avalanche diode with glass-passivated junction, optimized for fast response (<1 ns) to ESD and lightning-induced transients. Its thermal resistance (RθJA = 100 °C/W) and junction temperature limit (TJ = 150 °C) support operation in compact PCB layouts with minimal copper pad area (0.2" × 0.2").
The device uses a single PN junction structure with cathode band marking, designed for automated placement and reflow soldering per J-STD-020 MSL Level 1 (peak 260 °C). Its 600 W rating applies only under defined 10/1000 μs waveform conditions and derates linearly above TA = 25 °C per Figure 2 of the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 136 V - Maximum continuous reverse operating voltage before significant leakage; defines safe DC bias margin for 160 V nominal systems. |
| VBR (min) | 152 V - Minimum breakdown voltage at 1 mA test current; ensures reliable avalanche conduction onset during overvoltage events. |
| VC @ IPPM | 219 V - Clamping voltage at 2.7 A peak pulse current; determines maximum voltage seen by protected downstream circuitry. |
| IPPM | 2.7 A - Peak pulse current capability under 10/1000 μs waveform; defines surge energy handling (600 W) at specified test condition. |
| ID @ VWM | <1.0 μA - Reverse leakage at 136 V; critical for low-power standby circuits and battery-backed systems. |
| TJ max | 150 °C - Maximum junction temperature; sets thermal design limits for sustained power dissipation and ambient operating range. |
| Package | SMB (DO-214AA) - Standardized 2-pin surface-mount outline with 0.220" × 0.130" footprint; compatible with industry-standard pick-and-place and reflow profiles. |
Pinout & Package
SMB (DO-214AA) package: molded plastic case with matte tin-plated leads, UL 94 V-0 flammability rating, and polarity indicated by cathode band on unidirectional types.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / reverse voltage reference | Connected to lower-potential side (e.g., ground or return path); defines directionality of clamping action. |
| Cathode | Avalanche conduction terminal / clamping output | Connected to protected line (e.g., 160 V rail); conducts when reverse voltage exceeds VBR, shunting surge to anode. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control units, body electronics, and ADAS sensors requiring extended temperature and reliability validation. |
| Halogen-free & RoHS-compliant | Meets environmental compliance requirements for global automotive and industrial markets without compromising electrical performance. |
| 600 W peak pulse power (10/1000 μs) | Handles high-energy transients such as ISO 7637-2 Pulse 1/2a/5a in 12 V/24 V vehicle networks without degradation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ160A-E3/5B | Same VWM (136 V), identical SMB package, but rated for 400 W peak power (vs. 600 W) and not AEC-Q101 qualified. | Limited to commercial-grade consumer/industrial use; unsuitable for automotive environments requiring lifetime surge endurance validation. | Select when cost sensitivity outweighs automotive qualification and 600 W surge headroom is unnecessary. |
| 1.5SMC160AHE3_A/H | Higher power rating (1500 W), same VWM/VC, but larger SMC (DO-214AB) package (0.280" × 0.175") and higher leakage (5 μA). | Requires PCB layout change; better suited for high-energy industrial mains protection where space permits larger footprint. | Choose when system-level surge testing exceeds 600 W requirements and board real estate allows SMC package. |
Compared with SMAJ160A-E3/5B and 1.5SMC160AHE3_A/H, the P6SMB160AHM3/I uniquely delivers automotive-grade reliability, 600 W capability, and halogen-free compliance in the smallest standardized SMB footprint - making it optimal for space-constrained, high-assurance 24 V systems.

FAQ
What is the clamping voltage of the P6SMB160AHM3/I under its rated peak pulse current?
The P6SMB160AHM3/I has a maximum clamping voltage (VC) of 219 V at its rated peak pulse current (IPPM) of 2.7 A 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 surge events. The P6SMB160AHM3/I maintains this clamping performance across its full operating temperature range (-65 °C to +150 °C) with minimal drift.
Is the P6SMB160AHM3/I suitable for automotive applications?
Yes, the P6SMB160AHM3/I is AEC-Q101 qualified (suffix HM3 denotes halogen-free, RoHS-compliant, and automotive-grade version), validated for use in engine control units, body electronics, and ADAS subsystems. Its construction includes glass-passivated junction, MSL Level 1 rating, and guaranteed performance over -65 °C to +150 °C junction temperature - all confirmed in Vishay's qualification report referenced in datasheet 88370. The P6SMB160AHM3/I meets automotive surge immunity standards including ISO 7637-2.
What does the "HM3/I" suffix mean in P6SMB160AHM3/I?
The "HM3" suffix indicates halogen-free, RoHS-compliant, and AEC-Q101 qualified construction; "I" specifies packaging in 13-inch diameter tape-and-reel format with 3200 units per reel. This ordering code aligns with Vishay's standard nomenclature in Table "ORDERING INFORMATION" on page 3 of datasheet 88370. The P6SMB160AHM3/I is fully compatible with standard SMT pick-and-place equipment and reflow profiles per J-STD-020.
How does the P6SMB160AHM3/I compare to bidirectional TVS diodes with the same voltage rating?
The P6SMB160AHM3/I is unidirectional and intended for DC-biased lines where polarity is fixed (e.g., positive 24 V rails), offering lower leakage (<1.0 μA at 136 V) than equivalent bidirectional parts like P6SMB160CAHM3/I (which exhibit ~5× higher leakage). Bidirectional variants lack polarity marking and conduct in both directions, making them suitable for AC or floating signal lines - but the P6SMB160AHM3/I delivers superior DC blocking performance where directionality is known and controlled.
What is the thermal resistance of the P6SMB160AHM3/I, and how does it affect PCB layout?
The P6SMB160AHM3/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on minimum recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in Figure 6 of datasheet 88370. This value assumes no additional heatsinking; increasing copper area or adding thermal vias reduces RθJA. For continuous power dissipation near its 5.0 W rating, the P6SMB160AHM3/I requires careful thermal management - but for transient suppression, its 600 W capability relies on short-duration energy absorption, not steady-state cooling.
