Product details
Overview
VTVS11GSMF-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 low-voltage DC lines. It features 11.2 V maximum stand-off voltage (VRWM), 12.99–13.52 V reverse breakdown voltage (VBR) at 1 mA, 21.75 A peak pulse current (IPPM), 18.0 V maximum clamping voltage (VC) at IPPM, and ±30 kV IEC 61000-4-2 ESD immunity - deployed in automotive infotainment power rails and industrial sensor interfaces.
For engineers reviewing the VTVS11GSMF-HM3-18 datasheet, VTVS11GSMF-HM3-18 pinout, VTVS11GSMF-HM3-18 application, or VTVS11GSMF-HM3-18 equivalent, key selection criteria include its ±2 % VBR tolerance, halogen-free SMF package with MSL level 1 rating, 1.08 mm height for space-constrained PCBs, and AEC-Q101 qualification suitability for automotive-grade designs.
Technical Context
This device operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its precisely specified breakdown range (12.99–13.52 V). Its low clamping ratio (VC/VRWM ≈ 1.61) ensures robust overvoltage suppression while minimizing stress on downstream ICs during 10/1000 μs transients.
Designed for surface-mount reflow soldering per J-STD-020 class 2 conditions (peak 260 °C), it delivers stable performance across -55 °C to +175 °C junction temperature and supports high-reliability applications via halogen-free molding compound and whisker-tested terminations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 400 W (10/1000 μs waveform - sustains automotive load-dump and ISO 7637-2 pulse 1/2/5a surges) |
| Stand-off Voltage (VRWM) | 11.2 V max - blocks normal operation voltage while remaining inactive below system overvoltage threshold |
| Breakdown Voltage (VBR) | 12.99–13.52 V at IT = 1 mA - tight ±2 % tolerance enables precise protection margin setting |
| Clamping Voltage (VC) | 18.0 V at IPPM = 21.75 A - limits transient voltage seen by protected IC to safe level during worst-case surge |
| ESD Rating | ±30 kV contact / ±30 kV air (IEC 61000-4-2) - meets stringent electrostatic discharge immunity for exposed connectors |
| Junction Temp Range | -55 °C to +175 °C - supports under-hood automotive and industrial environments without derating |
| Package | SMF (DO-219AB) - low-profile 3.9 × 1.9 × 1.08 mm footprint compatible with SOD-123W layout standards |

Use Scenario: Overvoltage protection on USB-C VBUS (5 V nominal) during adapter hot-swap or faulty charger events. IC Role / Device Role / Timing Role: Stand-off voltage (11.2 V) exceeds VBUS max (5.5 V), allowing full pass-through during normal operation while clamping >12 V faults. Use Value: 400 W peak power rating handles short-duration 20 V surges common in USB PD negotiation failures. |
Use Scenario: Protection of 3.3 V or 5 V supply to battery-powered IoT sensors exposed to ESD during field installation. IC Role / Device Role / Timing Role: Placed at board edge connector, shunting ESD energy directly to chassis ground before entering regulator and microcontroller. Use Value: 1.08 mm profile enables placement in compact sensor housings where height clearance is limited to <1.2 mm. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11A | ±5 % VBR tolerance (11.1–12.3 V), same SMF package, 400 W rating | Lacks AEC-Q101 qualification and ±30 kV ESD rating; lower clamping ratio (17.0 V) | Select when cost sensitivity outweighs automotive qualification and tighter VBR control |
| TPSMD11A | Same ±2 % VBR, but DO-214AB (SMB) package (2.7 mm height), 400 W rating | Higher profile incompatible with ultra-low-height layouts; identical electrical specs otherwise | Choose only if existing SMB footprint is fixed and height constraint is relaxed |

FAQ
What is the meaning of "HM3" in VTVS11GSMF-HM3-18?
The "HM3" suffix in VTVS11GSMF-HM3-18 indicates halogen-free (H), lead-free (M), and 3 k per 7″ reel packaging (3), with "-18" denoting tape-and-reel orientation per carrier tape specification. This configuration ensures compliance with automotive material standards and automated SMT assembly readiness. VTVS11GSMF-HM3-18 meets J-STD-020 class 2 reflow requirements and ships with MSL level 1 handling instructions.
Is VTVS11GSMF-HM3-18 AEC-Q101 qualified?
VTVS11GSMF-HM3-18 is offered in an AEC-Q101 qualified version - confirmed in Vishay's official documentation (Rev. 2.2, 19-Nov-2021, Doc. #85891). The qualification covers temperature cycling, high-temperature reverse bias, and ESD stress testing per AEC-Q101-004. VTVS11GSMF-HM3-18 must be ordered with appropriate automotive-grade ordering codes (e.g., -HM3-18 variant with AEC-Q101 flag) to receive certified units.
How does VTVS11GSMF-HM3-18 compare to VTVS11ASMF-HM3-18?
VTVS11GSMF-HM3-18 has ±2 % VBR tolerance (12.99–13.52 V), while VTVS11ASMF-HM3-18 has ±5 % (12.6–13.9 V). Both share identical package, clamping voltage (18.0 V), and peak power (400 W), but the "G" variant enables tighter protection margins in precision 12 V systems. VTVS11GSMF-HM3-18 is preferred for automotive applications where VBR consistency directly impacts system-level surge resilience.
What is the thermal resistance (RthJL) of VTVS11GSMF-HM3-18?
VTVS11GSMF-HM3-18 has a thermal resistance RthJL of 20 K/W when mounted on an infinite heat sink - critical for calculating junction temperature rise during repetitive surge events. This value assumes ideal copper plane conduction; actual board-level RthJA will vary based on PCB copper area and layer count. For sustained surge duty cycles, VTVS11GSMF-HM3-18 must be thermally anchored using recommended footprint (1.3 × 1.3 mm pads) per Vishay S8-V-3915.01-001.
Can VTVS11GSMF-HM3-18 be used for bidirectional protection?
No - VTVS11GSMF-HM3-18 is a unidirectional TVS diode, designed only for positive-going transients on lines referenced to ground. It lacks symmetrical breakdown behavior and cannot suppress negative surges. For bidirectional protection (e.g., data lines like RS-485), a dedicated bidirectional part such as VTVS11B or SMAJ11CA is required. Using VTVS11GSMF-HM3-18 in reverse-biased configurations may result in permanent damage or unreliable clamping.
