Product details
Overview
VTVS52GSMF-M3-18 from Vishay Semiconductors is a unidirectional 400 W TransZorb® transient voltage suppressor diode in SMF (DO-219AB) package, designed for ESD and surge protection of low-voltage DC lines. It features a 52.2 V maximum stand-off voltage (VRWM), 60.76–63.24 V reverse breakdown voltage (VBR) at 1 mA, and clamps to ≤89 V at 4.41 A peak pulse current under 10/1000 μs waveform - used in automotive infotainment power rail protection.
For engineers reviewing the VTVS52GSMF-M3-18 datasheet, VTVS52GSMF-M3-18 pinout, VTVS52GSMF-M3-18 application, or VTVS52GSMF-M3-18 equivalent, key selection criteria include ±2 % VBR tolerance, 242 pF junction capacitance at 0 V, -55 °C to +175 °C operating temperature range, AEC-Q101 qualification status, and compatibility with SOD-123W footprint.
Technical Context
This device operates as a unidirectional avalanche diode, triggering when reverse voltage exceeds its precisely specified breakdown threshold (60.76–63.24 V). Its low dynamic impedance enables fast clamping response (<1 ns), limiting transient energy delivered to downstream circuitry during ESD events per IEC 61000-4-2 (±30 kV contact/air discharge).
The SMF package provides thermal resistance of 20 K/W to leads (RthJL) and supports wave/reflow soldering up to 260 °C peak. With 1.08 mm height and halogen-free molding compound rated UL 94 V-0, it meets space-constrained and automotive reliability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 400 W (10/1000 μs waveform; defines maximum transient energy absorption capability) |
| Stand-off Voltage (VRWM) | 52.2 V (maximum continuous reverse voltage before significant leakage; sets operating margin) |
| Breakdown Voltage (VBR) | 60.76–63.24 V at 1 mA (±2 % tolerance; ensures precise trigger point for overvoltage protection) |
| Clamping Voltage (VC) | ≤89 V at IPPM = 4.41 A (limits voltage seen by protected IC during worst-case surge) |
| Junction Capacitance | 242 pF at VR = 0 V, 1 MHz (impacts signal integrity in high-speed data line protection) |
| ESD Rating | ±30 kV contact / ±30 kV air (IEC 61000-4-2 Level 4; qualifies for harsh industrial/automotive environments) |
| Operating Temperature | -55 °C to +175 °C (supports under-hood automotive and industrial control applications) |
Pinout & Package
Package: SMF (DO-219AB), low-profile surface-mount case compatible with SOD-123W footprint; dimensions 3.9 × 1.9 × 1.08 mm (L × W × H); cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward conduction | Connected to protected line's lower-potential side (e.g., GND or return path) |
| Cathode | Current exit terminal during reverse-biased clamping | Connected to protected line's higher-potential side (e.g., 52 V supply rail); marked with bar |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % VBR tolerance | Enables tighter design margins vs. ±5 % variants, reducing overdesign risk in precision voltage rails |
| "Low-Noise" fast response | Sub-nanosecond turn-on minimizes overshoot during ESD transients, protecting sensitive analog front-ends |
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock |
| Halogen-free & RoHS-compliant | Meets automotive OEM environmental requirements and supports lead-free reflow assembly (260 °C peak) |
| SOD-123W footprint compatibility | Enables drop-in replacement in existing layouts using standard SOD-123W land patterns |
Applications
| Automotive Infotainment Power Rail Protection | Industrial CAN Bus Transceiver Protection |
|---|---|
|
Use Scenario: Protecting 5V–12V power inputs of head unit MCUs and display drivers against load dump and jump-start surges. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between VCC and GND, clamping transients before they reach LDOs or PMICs. Use Value: With 52.2 V VRWM and 89 V VC, it avoids false triggering during normal operation while suppressing >100 V spikes within 1 ns. |
Use Scenario: Safeguarding CANH/CANL pins of transceivers against ESD and inductive switching noise in factory automation nodes. IC Role / Device Role / Timing Role: Bidirectional protection not applicable; this unidirectional part used on power-supply side only (e.g., VCC-to-GND), not signal lines. Use Value: 242 pF capacitance avoids signal distortion on 1 Mbps CAN bus; ±30 kV ESD rating exceeds ISO 10605 requirements. |
| Telecom PoE+ Midspan Power Feed Protection | Medical Sensor Module DC Input Protection |
|
Use Scenario: Guarding 57 V DC output of IEEE 802.3at midspan injectors against lightning-induced surges on Ethernet cables. IC Role / Device Role / Timing Role: Primary clamping device on secondary-side DC output, coordinated with upstream MOVs and gas discharge tubes. Use Value: 400 W peak power rating handles 10/1000 μs surges up to 4.41 A; 175 °C TJ max supports sealed enclosure thermal profiles. |
Use Scenario: Securing 24 V DC input of portable ultrasound probe modules exposed to electrostatic discharge during clinical handling. IC Role / Device Role / Timing Role: Final-stage protection element mounted adjacent to connector, shunting ESD energy directly to chassis ground. Use Value: AEC-Q101 qualification ensures robustness across repeated sterilization cycles; low-profile SMF package fits tight PCB real estate. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ52A-E3/5A | ±5 % VBR tolerance (61.2–68.4 V), 400 W rating, SMA package (DO-214AC) | Larger footprint (4.5 × 2.7 mm), higher RthJA, no AEC-Q101 qualification | Select for cost-sensitive industrial designs where ±5 % VBR margin is acceptable and board space allows SMA |
| TPSMD52A | ±5 % VBR (61.2–68.4 V), 400 W, same DO-219AB package, but not AEC-Q101 qualified | Identical mechanical fit; lacks automotive reliability validation and tighter VBR tolerance | Choose for non-automotive applications requiring identical SMF footprint but without AEC-Q101 requirement |
Compared with VTVS52GSMF-M3-18, SMAJ52A-E3/5A offers broader VBR spread and larger package, increasing layout risk in space-constrained automotive modules; TPSMD52A matches the SMF footprint but omits AEC-Q101 validation and ±2 % precision, limiting use in safety-critical vehicle subsystems.

FAQ
What is the exact breakdown voltage range for VTVS52GSMF-M3-18?
The VTVS52GSMF-M3-18 has a reverse breakdown voltage (VBR) range of 60.76 V to 63.24 V at IT = 1 mA and TJ = 25 °C, reflecting its ±2 % tolerance grade. This tight specification ensures predictable clamping behavior in precision 52 V power rail protection circuits, and is confirmed in Vishay document 85891, Rev. 2.2.
Is VTVS52GSMF-M3-18 qualified for automotive applications?
Yes, VTVS52GSMF-M3-18 is AEC-Q101 qualified, meaning it has passed stress tests for temperature cycling, high-temperature operating life, and mechanical shock required for automotive electronic components. This qualification is explicitly stated in the Vishay datasheet and applies to the VTVSxxGSMF series including VTVS52GSMF-M3-18.
What does the "-M3-18" suffix indicate in VTVS52GSMF-M3-18?
The "-M3-18" suffix denotes tape-and-reel packaging: M = RoHS-compliant, lead (Pb)-free terminations; 3 = 3 k units per 7″ reel (8 mm tape); and 18 = date code for 2018. This packaging format is optimized for automated SMT placement and aligns with Vishay's standard ordering nomenclature for the VTVSxxGSMF family.
Can VTVS52GSMF-M3-18 be used on high-speed data lines like USB or HDMI?
No - VTVS52GSMF-M3-18 is not recommended for high-speed data line protection due to its 242 pF junction capacitance at 0 V, which would severely degrade signal integrity above ~10 MHz. It is intended for DC power rail protection (e.g., 52 V supply lines), not signal-line ESD suppression; lower-capacitance TVS devices are required for USB/HDMI interfaces.
What is the maximum clamping voltage of VTVS52GSMF-M3-18 under surge conditions?
The maximum reverse clamping voltage (VC) of VTVS52GSMF-M3-18 is 89 V at IPPM = 4.41 A with a 10/1000 μs waveform. This value is measured per standard test conditions and represents the peak voltage imposed on the protected circuit during worst-case transient events, ensuring downstream components remain within safe operating limits.
