Product details
Overview
P6SMB11CA-M3/52 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on signal and power lines. It features a 9.4 V stand-off voltage (VWM), 15.6 V maximum clamping voltage (VC) at 5.0 A peak pulse current, and 600 W peak pulse power capability with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial and automotive electronics.
For engineers reviewing the P6SMB11CA-M3/52 datasheet, P6SMB11CA-M3/52 pinout, P6SMB11CA-M3/52 application, or P6SMB11CA-M3/52 equivalent, key selection criteria include bidirectional clamping performance, low incremental surge resistance, AEC-Q101 qualification eligibility (via HM3 suffix), RoHS/halogen-free compliance, and compatibility with automated SMT placement on standard PCB pad layouts.
Technical Context
This device operates as a voltage-clamped transient protector with symmetrical breakdown behavior in both directions due to its bidirectional construction. Its glass-passivated junction ensures stable reverse leakage (<5.0 μA at VWM) and fast response time (<1.0 ns), enabling effective suppression of ESD, lightning-induced surges, and inductive switching spikes.
The P6SMB11CA-M3/52 delivers 600 W peak pulse power handling under JEDEC-standard 10/1000 μs waveform conditions, with thermal resistance RθJA = 100 °C/W and RθJL = 20 °C/W. It supports continuous operation up to TJ = 150 °C and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak temperature tolerance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 9.4 V - Maximum continuous reverse working voltage before clamping initiates |
| VBR (Breakdown) | 10.5–11.6 V at 1.0 mA test current - Confirmed symmetric breakdown threshold in both directions |
| VC (Clamping) | 15.6 V at 5.0 A IPPM - Peak voltage seen by protected circuit during worst-case transient |
| PPPM | 600 W - Surge energy absorption capacity under standardized 10/1000 μs waveform |
| IPPM | 5.0 A - Peak pulse current corresponding to VC = 15.6 V |
| Leakage (ID) | <5.0 μA at VWM - Minimal DC loading on signal/power lines during normal operation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ11CA-T | Same VWM (9.4 V), identical SMB package, but lower PPPM (600 W same), higher VC (17.0 V at 5.0 A) | Less aggressive clamping; suitable where margin allows higher protected-line voltage excursion | Select when tighter VC is not required and alternate sourcing is needed |
| 1.5KE11CA | Higher power (1500 W), axial DO-201 package, larger footprint, slower thermal response | Not SMT-compatible; requires through-hole layout and manual assembly; better for high-repetition surges | Choose only if board space permits axial mounting and system duty cycle exceeds SMB thermal limits |
Compared with SMBJ11CA-T and 1.5KE11CA, the P6SMB11CA-M3/52 offers optimal balance of SMT manufacturability, low-profile packaging, precise 15.6 V clamping, and halogen-free compliance - making it preferred for space-constrained, high-volume industrial and automotive PCBs requiring consistent reflow yield and environmental compliance.

FAQ
What is the clamping voltage of P6SMB11CA-M3/52 at its rated peak pulse current?
The P6SMB11CA-M3/52 has a maximum clamping voltage (VC) of 15.6 V at 5.0 A peak pulse current (IPPM) under 10/1000 μs waveform conditions. This value is measured across both terminals during transient suppression and defines the upper voltage limit imposed on protected circuitry. The P6SMB11CA-M3/52 maintains this clamping performance consistently across its operating temperature range and lifetime.
Is P6SMB11CA-M3/52 suitable for automotive applications?
Yes - the P6SMB11CA-M3/52 uses the HM3 suffix designation, indicating halogen-free, RoHS-compliant construction with AEC-Q101 qualification available via the HM3_B or HM3_I ordering variants. While the base P6SMB11CA-M3/52 itself is commercial-grade, its material set and process flow align with automotive reliability requirements, and Vishay provides AEC-Q101 test reports upon request for qualified lots. Designers should specify HM3_B/H or HM3_B/I for certified automotive use.
How does the bidirectional design of P6SMB11CA-M3/52 affect its PCB layout?
The P6SMB11CA-M3/52 has no polarity marking and functions identically in both directions, eliminating orientation constraints during placement. PCB layout requires symmetric 0.2" x 0.2" (5.0 mm x 5.0 mm) copper pads per terminal as specified in the datasheet, with no need for cathode/anode routing differentiation. This simplifies layout, reduces assembly errors, and enables direct replacement of unidirectional TVS diodes in AC-coupled or differential signal paths - all while retaining full P6SMB11CA-M3/52 functionality.
What is the thermal resistance of P6SMB11CA-M3/52, and how does it impact power derating?
The P6SMB11CA-M3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead resistance (RθJL) of 20 °C/W. At ambient temperatures above 25 °C, its 5.0 W steady-state power dissipation must be linearly derated - for example, to ~3.5 W at 75 °C ambient. These values assume minimum recommended pad layout; inadequate copper area increases RθJA and accelerates thermal runaway during repetitive surges. The P6SMB11CA-M3/52's thermal profile is validated per JEDEC standards and documented in Fig. 2 of its datasheet.
Can P6SMB11CA-M3/52 replace older P6SMB11CA-E3/52 in existing designs?
Yes - the P6SMB11CA-M3/52 is a direct drop-in replacement for P6SMB11CA-E3/52, sharing identical electrical specifications, SMB (DO-214AA) package dimensions, pinout, and thermal characteristics. The only difference is material composition: M3 denotes halogen-free construction versus E3's standard RoHS compliance. No PCB or schematic changes are required, and the P6SMB11CA-M3/52 maintains full compatibility with existing reflow profiles, test fixtures, and reliability validation data for the P6SMB11CA-M3/52 family.
