Product details
Overview
VTVS52GSMF-HM3-18 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 52.2 V DC power rails and signal lines. It features 60.76–63.24 V reverse breakdown voltage (VBR), ±2 % tolerance, 89 A peak pulse current (IPPM), 89 V maximum clamping voltage (VC) at IPPM, and 242 pF typical junction capacitance - deployed in automotive infotainment power inputs and industrial sensor interfaces.
For engineers reviewing the VTVS52GSMF-HM3-18 datasheet, VTVS52GSMF-HM3-18 pinout, VTVS52GSMF-HM3-18 application, or VTVS52GSMF-HM3-18 equivalent, key selection criteria include its AEC-Q101 qualification, halogen-free SOD-123W-compatible SMF package, ±30 kV IEC 61000-4-2 ESD immunity, low thermal resistance (20 K/W), and precise 2 % VBR tolerance for tight-clamp system designs.
Technical Context
This device operates as a unidirectional avalanche diode with fast response time enabled by Vishay's "Low-Noise" technology. Its clamping behavior is defined under 10/1000 μs waveform conditions, delivering 89 V clamping at 89 A while maintaining 52.2 V stand-off voltage (VRWM) and only 0.05 μA leakage at rated VRWM.
The SMF (DO-219AB) package supports wave and reflow soldering per J-STD-020 MSL level 1, with peak temperature up to 260 °C. Junction temperature range spans −55 °C to +175 °C, enabling use in under-hood automotive and high-temperature industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 52.2 V - Maximum continuous reverse working voltage before significant leakage; sets upper limit for protected circuit DC bias. |
| VBR @ IT = 1 mA | 60.76–63.24 V - Tight ±2 % tolerance ensures predictable turn-on across production lots and temperature. |
| VC @ IPPM | 89 V - Clamping voltage during 10/1000 μs surge; limits transient energy delivered to downstream ICs. |
| IPPM | 89 A - Peak pulse current handling capacity under standardized surge waveform; defines robustness against ISO 7637-2 Pulse 1/2a/5a events. |
| CD @ VR = 0 V, f = 1 MHz | 242 pF - Junction capacitance impacts high-speed signal integrity; suitable for <10 Mbps data lines or DC power rails. |
| ESD Rating | ±30 kV contact / ±30 kV air (IEC 61000-4-2) - Full-system ESD immunity without external shielding or filtering. |
| TJ max. | +175 °C - Enables placement near heat sources (e.g., power converters) without derating in automotive modules. |
Pinout & Package
Package: SMF (DO-219AB), low-profile surface-mount case compatible with SOD-123W footprint; dimensions: 3.9 mm × 1.9 mm × 1.08 mm (L × W × H); cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry during forward conduction; tied to protected line ground or low-side return path | Provides low-impedance discharge path to ground when transient exceeds VBR; must connect to lowest-impedance ground plane. |
| Cathode | Current exit during reverse-biased clamping; connected to protected line (e.g., 52.2 V rail) | Acts as the "protected node" terminal; clamps voltage to ≤89 V relative to anode during surge events. |

|---|---|
Use Scenario: Protecting 52 V supply rail of head unit MCU and display driver ICs from load dump and jump-start surges. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed directly at connector entry point, clamping transients before they reach LDOs and PMICs. Use Value: Withstands 89 A pulses and maintains 89 V clamping, preventing overvoltage damage to 65 V-rated input stages while adding only 242 pF loading. |
Use Scenario: Safeguarding CAN transceiver VCC pins in factory automation gateways exposed to inductive switching noise. IC Role / Device Role / Timing Role: Standoff protector on 5 V or 3.3 V auxiliary supply feeding isolated CAN PHY; co-located with ferrite bead for combined ESD/surge/noise suppression. Use Value: ±30 kV IEC 61000-4-2 rating eliminates need for secondary ESD components; 20 K/W RthJL enables thermal stability during repeated 10/1000 μs events. |
| Telecom Remote Radio Unit (RRU) DC Feed | Medical Imaging Sensor Bias Supply |
Use Scenario: Securing 48–56 V DC power feed to outdoor 5G RRUs subject to lightning-induced surges on long cable runs. IC Role / Device Role / Timing Role: Primary surge clamp on PoE++-derived DC input, upstream of DC/DC converter and GaN amplifier bias circuits. Use Value: 400 W peak power rating handles multi-kA induced currents; DO-219AB package allows compact layout with minimal trace inductance for optimal clamping speed. |
Use Scenario: Protecting high-precision analog bias supplies (e.g., for X-ray detector ASICs) where leakage and capacitance must be tightly controlled. IC Role / Device Role / Timing Role: Low-leakage (0.05 μA @ 52.2 V) TVS on ultra-stable 52.2 V reference rail, minimizing DC error contribution. Use Value: Sub-μA leakage preserves mV-level accuracy; 242 pF capacitance avoids resonance with low-ESR ceramic filters used in medical-grade LDO outputs. |
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), higher VC (93.6 V), SMA package (larger footprint) | Less precise clamping; requires PCB area increase (~2.5× SMF footprint); not AEC-Q101 qualified | Select when cost sensitivity outweighs precision and space constraints; verify thermal margin due to higher RthJA. |
| TPSMD52A (Texas Instruments) | Same VRWM (52 V), ±5 % VBR, 93.6 V VC, DO-214AB package; no AEC-Q101 or IEC 61000-4-2 certification stated | Lacks automotive qualification and full ESD rating; lower surge robustness (400 W same, but no published IPPM curve validation) | Acceptable for commercial-grade industrial controls where AEC-Q101 and ±30 kV ESD are not mandated. |
Compared with SMAJ52A-E3/5A and TPSMD52A, VTVS52GSMF-HM3-18 delivers tighter ±2 % VBR control, lower clamping (89 V vs. 93.6 V), AEC-Q101 qualification, and verified ±30 kV ESD performance - making it the preferred choice for automotive and high-reliability industrial designs requiring predictable, repeatable surge response.

FAQ
What is the exact reverse breakdown voltage range for VTVS52GSMF-HM3-18?
The VTVS52GSMF-HM3-18 has a reverse breakdown voltage (VBR) of 60.76 V minimum to 63.24 V maximum at IT = 1 mA and TJ = 25 °C, reflecting its ±2 % tolerance grade. This tight specification ensures consistent clamping onset across temperature and production lots, critical for protecting 52.2 V rails in automotive modules where margin is constrained.
Is VTVS52GSMF-HM3-18 qualified for automotive use?
Yes, VTVS52GSMF-HM3-18 is AEC-Q101 qualified, having passed stress tests including temperature cycling, mechanical shock, and high-temperature operating life. This qualification confirms its suitability for under-hood and cabin applications such as infotainment power inputs and ADAS sensor interfaces where reliability under thermal and vibration stress is mandatory.
What does the "HM3-18" suffix indicate in VTVS52GSMF-HM3-18?
The "HM3-18" suffix denotes halogen-free (H), lead-free tin plating (M), 3 k per 7″ reel packaging (3), and tape-and-reel orientation code -18 (standard cathode-up orientation per SMF carrier tape spec). This matches Vishay's ordering convention in Document 85891 and ensures compatibility with automated SMT placement equipment calibrated for DO-219AB devices.
How does the clamping performance of VTVS52GSMF-HM3-18 compare to standard 52 V TVS diodes?
VTVS52GSMF-HM3-18 clamps to 89 V at 89 A (10/1000 μs), which is 4.6 V lower than typical ±5 % 52 V TVS diodes (e.g., SMAJ52A at 93.6 V). This 5 % reduction in clamping voltage directly improves system-level surge margin, especially for ICs with 90 V absolute maximum ratings - a key advantage in space-constrained automotive layouts.
Can VTVS52GSMF-HM3-18 be used in bidirectional configurations?
No, VTVS52GSMF-HM3-18 is a unidirectional TVS diode, intended for DC rail protection where polarity is fixed. For AC or bidirectional signal line protection (e.g., RS-485), a dedicated bidirectional variant like VTVS52GSMF-BD would be required - the "G" in VTVS52GSMF-HM3-18 refers only to ±2 % VBR tolerance, not polarity.
