Product details
Overview
VTVS52GSMF-M3-08 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 - ideal for protecting automotive infotainment power rails and industrial sensor interfaces.
For engineers reviewing the VTVS52GSMF-M3-08 datasheet, VTVS52GSMF-M3-08 pinout, VTVS52GSMF-M3-08 application, or VTVS52GSMF-M3-08 equivalent, key selection criteria include ±2 % VBR tolerance, 242 pF typical junction capacitance at 0 V, AEC-Q101 qualification option, IEC 61000-4-2 ±30 kV ESD immunity, and compatibility with SOD-123W footprint constraints.
Technical Context
This device operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its precisely specified breakdown range (60.76–63.24 V). Its low-clamping behavior (VC ≤ 89 V at IPPM = 4.41 A) ensures downstream ICs remain within safe operating limits during transients.
The SMF package delivers thermal resistance of 20 K/W (junction-to-lead, infinite heat sink), supports wave and reflow soldering up to 260 °C peak, and meets halogen-free and MSL level 1 requirements - enabling robust integration into high-reliability automotive and industrial PCB assemblies.
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 IT = 1 mA (±2 % tolerance; enables precise overvoltage trip point control) |
| Clamping Voltage (VC) | ≤ 89 V at IPPM = 4.41 A (limits voltage seen by protected circuit during worst-case surge) |
| Junction Capacitance (CD) | 242 pF at VR = 0 V, f = 1 MHz (impacts signal integrity on high-speed data lines; requires layout de-tuning if used near USB/CAN) |
| ESD Immunity | ±30 kV contact & air discharge per IEC 61000-4-2 (meets automotive interior electronics ESD robustness requirements) |
| Operating Temperature | −55 °C to +175 °C (supports under-hood automotive and industrial ambient conditions) |

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 | ±5 % VBR tolerance (52.2–57.7 V), 200 W PPPM, SMA package (larger footprint) | Lower power rating and looser tolerance reduce precision in tight-margin designs | Select when cost sensitivity outweighs need for ±2 % accuracy and 400 W headroom |
| SMCJ51A | ±5 % VBR (51.0–56.4 V), 1500 W PPPM, SMC package (5.3 mm × 4.6 mm) | Higher power but larger size and higher capacitance (400 pF) limit use in space-constrained or high-speed layouts | Choose for higher-energy surges where board area permits and capacitance is not critical |
Compared with SMAJ52A and SMCJ51A, VTVS52GSMF-M3-08 delivers superior VBR precision and power density in a compact DO-219AB outline - making it optimal for automotive modules and portable industrial devices where layout space, thermal performance, and ESD consistency are prioritized.

FAQ
What is the exact breakdown voltage range for VTVS52GSMF-M3-08?
The VTVS52GSMF-M3-08 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 consistent clamping behavior across production lots and supports designs requiring precise overvoltage thresholds. The VTVS52GSMF-M3-08 maintains this VBR range across its full operating temperature span.
Is VTVS52GSMF-M3-08 qualified for automotive applications?
VTVS52GSMF-M3-08 is offered in an AEC-Q101 qualified version (e.g., VTVS52GSMF-HM3-08), validated for automotive use including temperature cycling, mechanical shock, and humidity testing. While the base VTVS52GSMF-M3-08 part is not automatically qualified, the HM3 suffix denotes full AEC-Q101 compliance. Always verify the specific ordering code's qualification status before automotive deployment. The VTVS52GSMF-M3-08 itself shares identical electrical specs and packaging.
What is the maximum clamping voltage of VTVS52GSMF-M3-08 under surge conditions?
The VTVS52GSMF-M3-08 clamps to a maximum of 89 V when subjected to its rated peak pulse current of 4.41 A under the standardized 10/1000 μs waveform. This VC value is guaranteed across temperature and represents the highest voltage imposed on the protected line during worst-case transient events. The VTVS52GSMF-M3-08 achieves this with minimal overshoot due to its "Low-Noise" fast-response architecture.
Can VTVS52GSMF-M3-08 be used in bidirectional protection configurations?
No - VTVS52GSMF-M3-08 is a unidirectional TVS diode, intended only for DC line protection where polarity is fixed. It conducts in reverse avalanche above VRWM but blocks forward current like a standard diode. For bidirectional AC or differential signal protection, a dedicated bidirectional variant (e.g., VTVS52GSMF-BD) or back-to-back unidirectional pair would be required. The VTVS52GSMF-M3-08 datasheet explicitly specifies unidirectional polarity.
What is the thermal resistance and maximum junction temperature of VTVS52GSMF-M3-08?
The VTVS52GSMF-M3-08 has a thermal resistance RthJL of 20 K/W (junction-to-lead, mounted on infinite heat sink) and a maximum junction temperature (TJ) rating of +175 °C. This allows sustained operation in under-hood automotive or enclosed industrial environments. Derating curves in the datasheet define safe power dissipation versus ambient temperature - critical for validating thermal design when using the VTVS52GSMF-M3-08 in high-duty-cycle surge scenarios.
