Product details
Overview
P6SMB180A-M3/52 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 180 V standoff voltage (VWM), 246 V clamping voltage (VC) at 2.4 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform. It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients and lightning-induced surges in industrial and telecom power rails.
For engineers reviewing the P6SMB180A-M3/52 datasheet, P6SMB180A-M3/52 pinout, P6SMB180A-M3/52 application, or P6SMB180A-M3/52 equivalent, this part delivers verified clamping performance, halogen-free RoHS compliance (M3 suffix), AEC-Q101 qualification readiness, and MSL Level 1 moisture sensitivity - critical for high-reliability board-level surge protection design and automotive-grade BOM planning.
Technical Context
This TVS operates as a unidirectional avalanche diode with cathode-banded polarity, leveraging glass-passivated junction technology for stable breakdown behavior and low incremental surge resistance. Its 10/1000 μs waveform response enables robust suppression of fast-rising transients while maintaining sub-1 ns intrinsic response time.
Thermal performance is defined by RθJA = 100 °C/W and RθJL = 20 °C/W, requiring minimum 5.0 mm × 5.0 mm copper pads per terminal for rated 600 W pulse handling. The device is rated for TJ = –65 °C to +150 °C operation and meets JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 154 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC rail margin. |
| VBR (Breakdown Voltage) | 171–189 V at IT = 1.0 mA - Verified avalanche onset range; ensures predictable turn-on under transient stress. |
| VC (Clamping Voltage) | 246 V at IPPM = 2.4 A - Peak voltage seen by protected circuit during 10/1000 μs surge; determines downstream component stress. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capability per single 10/1000 μs event; enables IEC 61000-4-5 Level 4 compliance. |
| ID (Reverse Leakage) | 1.0 μA at VWM - Ultra-low leakage preserves system efficiency and prevents false triggering in high-impedance circuits. |
| TJ max. | +150 °C - Junction temperature limit enabling use in under-hood or enclosed industrial enclosures without derating. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, halogen-free, RoHS-compliant (M3 suffix), MSL Level 1, matte tin-plated leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Protected circuit anode connection point | Connects to positive rail or signal line being protected; reverse-biased during normal operation. |
| Anode | Reference/ground return path | Must be tied to low-impedance ground plane or chassis to ensure effective clamping and thermal dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 μs) | Enables single-device protection against IEC 61000-4-5 combination wave surges up to 4 kV (open-circuit) / 2 kA (short-circuit). |
| Glass passivated chip junction | Ensures long-term stability of VBR and VC across temperature and lifetime, with <0.1 %/°C drift and no parameter shift after 1000 surge cycles. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast transients, reducing risk of latch-up or gate oxide damage in downstream MOSFETs and ICs. |
| MSL Level 1, LF peak 260 °C | Supports standard lead-free reflow profiles without preconditioning or baking, simplifying SMT manufacturing flow. |
Applications
| Industrial Motor Drive Power Supply | Automotive Body Control Module (BCM) |

Use Scenario: Shields metering SoC and isolated RS-485 interface from EFT/burst noise and capacitor discharge events on AC/DC adapter output. IC Role / Device Role / Timing Role: Secondary-stage TVS on 5 V or 3.3 V regulated rail, acting after primary MOV or GDT suppression. Use Value: Provides precise, repeatable clamping at 246 V with <1 μA leakage, eliminating standby current degradation in battery-backed meters. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ180A | Same VWM (154 V), lower PPPM (400 W), SMA package (smaller thermal mass) | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 or repetitive industrial surges | Select P6SMB180A-M3/52 when 600 W pulse rating and SMB thermal robustness are required. |
| 1.5SMC180A | Same VWM and VC, but SMC package (higher RθJA = 125 °C/W), higher minimum pad area requirement | Requires larger PCB footprint and tighter thermal layout; less suitable for dense industrial modules | Choose P6SMB180A-M3/52 for space-constrained designs needing SMB footprint and proven 600 W reliability. |
Compared with SMAJ180A and 1.5SMC180A, P6SMB180A-M3/52 delivers superior thermal performance (RθJL = 20 °C/W), standardized MSL Level 1 handling, and halogen-free compliance out-of-box - making it the preferred choice for high-volume industrial and automotive-adjacent designs where manufacturability and surge margin are non-negotiable.

FAQ
What is the clamping voltage of P6SMB180A-M3/52 at its rated peak pulse current?
The P6SMB180A-M3/52 has a maximum clamping voltage (VC) of 246 V at a peak pulse current (IPPM) of 2.4 A with a 10/1000 μs waveform. This value is measured under standardized test conditions per JEDEC and is guaranteed across the full operating temperature range of –65 °C to +150 °C. The clamping voltage directly determines the maximum stress imposed on downstream components during surge events, making it a critical parameter for system-level robustness validation.
Is P6SMB180A-M3/52 suitable for automotive applications?
Yes - P6SMB180A-M3/52 is halogen-free and RoHS-compliant, and the P6SMB family offers AEC-Q101 qualified variants (e.g., P6SMB180AHM3_B/H). While the M3/52 suffix itself denotes commercial-grade halogen-free construction, its electrical specs, thermal ratings, and packaging meet foundational requirements for automotive subsystems such as body control modules and power distribution units. Full AEC-Q101 qualification requires the HM3_B or HM3_I suffix variant.
What is the meaning of the "M3" and "/52" in P6SMB180A-M3/52?
In P6SMB180A-M3/52, "M3" indicates halogen-free, RoHS-compliant construction with JESD201 Class 2 whisker resistance, while "/52" specifies packaging in 7-inch diameter plastic tape and reel containing 750 units. This ordering code ensures consistent material compliance and automated placement compatibility across high-volume SMT lines, distinguishing it from E3 (standard RoHS) or HM3 (AEC-Q101 qualified) variants.
How does P6SMB180A-M3/52 compare to bidirectional TVS diodes like P6SMB180CA?
P6SMB180A-M3/52 is unidirectional and features a cathode band for polarity-sensitive placement, whereas P6SMB180CA is bidirectional with symmetrical clamping in both directions and no polarity marking. The unidirectional version offers lower leakage (<1 μA at VWM) and slightly tighter VBR tolerance, making it preferable for DC rail protection where reverse conduction must be blocked. Bidirectional types are used for AC lines or data buses requiring symmetric surge handling.
What PCB layout guidance applies to P6SMB180A-M3/52 for optimal thermal and electrical performance?
For P6SMB180A-M3/52, Vishay specifies mounting on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated 600 W pulse power. Traces to ground must be short and wide to minimize inductance, and thermal vias under pads are recommended for enhanced heat transfer. Avoid routing sensitive signals near the TVS anode/cathode traces to prevent coupling of clamped transient energy into adjacent circuitry.
