Product details
Overview
VTVS52GSMF-HM3-08 from Vishay Semiconductors is a unidirectional 400 W TransZorb® transient voltage suppressor diode in SMF (DO-219AB) package, with 52.2 V stand-off voltage (VRWM), ±2 % breakdown voltage tolerance, and 89 A peak pulse current (10/1000 μs). It delivers robust ESD protection up to ±30 kV (contact/air) per IEC 61000-4-2 for automotive infotainment power rails.
For engineers reviewing the VTVS52GSMF-HM3-08 datasheet, VTVS52GSMF-HM3-08 pinout, VTVS52GSMF-HM3-08 application, or VTVS52GSMF-HM3-08 equivalent, key selection criteria include clamping voltage (89 V at IPPM), low capacitance (242 pF), AEC-Q101 qualification, halogen-free construction, and compatibility with SOD-123W footprint constraints.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, triggered when reverse voltage exceeds its 60.76–63.24 V breakdown range (VBR min/max at IT = 1 mA). Its thermal resistance is 20 K/W (junction-to-lead on infinite heat sink), enabling reliable operation up to TJ = +175 °C.
The device features "Low-Noise" fast-response technology with sub-nanosecond turn-on, optimized for protecting 52 V nominal systems such as automotive ADAS camera power supplies and industrial 48 V DC bus interfaces against lightning-induced surges and EFT events.

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 (Vishay) | Same VRWM (52 V), but ±5 % VBR tolerance (61.2–67.2 V); SMA package (DO-214AC), larger footprint (4.5 × 2.7 mm) | Higher clamping voltage (93.6 V) and 400 W rating; less precise breakdown onset | Select when cost sensitivity outweighs precision clamping or board space allows larger package |
| TPSMD52A (Texas Instruments) | Same VRWM (52 V), ±5 % VBR (61.2–67.2 V); DO-214AB package; 100 A IPPM (vs. 89 A); 93.6 V VC | Higher surge current handling but higher clamping; not AEC-Q101 qualified | Prefer for non-automotive industrial use where extended surge margin is critical and qualification is not required |
Compared with SMAJ52A-E3/5A and TPSMD52A, VTVS52GSMF-HM3-08 offers tighter ±2 % breakdown tolerance, lower 89 V clamping, AEC-Q101 qualification, and compact SMF footprint-making it optimal for space- and reliability-critical automotive 52 V systems.

FAQ
What is the breakdown voltage range for VTVS52GSMF-HM3-08?
The VTVS52GSMF-HM3-08 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 specification. This tight tolerance ensures consistent clamping behavior across production lots and temperature extremes, critical for protecting 52 V systems where overvoltage margin is constrained. The VTVS52GSMF-HM3-08 maintains this specification across its full operating temperature range.
Is VTVS52GSMF-HM3-08 qualified for automotive use?
Yes, VTVS52GSMF-HM3-08 is AEC-Q101 qualified, meaning it has passed stress tests for high-reliability automotive applications including temperature cycling, humidity bias, and mechanical shock. This qualification validates its suitability for under-hood and cabin modules such as ADAS cameras and body control units. The VTVS52GSMF-HM3-08 also meets halogen-free and RoHS requirements per Vishay's material categorization standards.
What is the maximum clamping voltage of VTVS52GSMF-HM3-08 during a surge event?
The maximum reverse clamping voltage (VC) of VTVS52GSMF-HM3-08 is 89 V at its rated peak pulse current of 89 A (10/1000 μs waveform). This value represents the highest voltage seen across the device during worst-case transient suppression, directly limiting stress on downstream components. The VTVS52GSMF-HM3-08 achieves this clamping performance while maintaining only 242 pF capacitance, minimizing impact on high-speed signal paths.
Can VTVS52GSMF-HM3-08 be used in reflow soldering processes?
Yes, VTVS52GSMF-HM3-08 is fully compatible with standard lead-free reflow soldering, with a peak temperature rating of 260 °C. Its SMF (DO-219AB) package is rated MSL level 1 per J-STD-020, eliminating the need for moisture-sensitive handling or baking prior to assembly. The VTVS52GSMF-HM3-08 also supports wave soldering, making it adaptable to mixed-technology PCB assembly flows.
What does the "HM3-08" suffix indicate in VTVS52GSMF-HM3-08?
The "HM3-08" suffix denotes halogen-free (H), lead-free tin plating (M), 3 k per 7″ reel packaging (3), and tape-and-reel format with 8 mm carrier tape width (-08). This packaging configuration supports automated SMT placement and meets environmental compliance mandates including RoHS and JEDEC J-STD-020. The VTVS52GSMF-HM3-08 is supplied in 3,000-unit reels with minimum order quantity of 30,000 units.
