Product details
Overview
VTVS17GSMF-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 16.9 V maximum stand-off voltage (VRWM), 19.6–20.4 V reverse breakdown voltage (VBR) at 1 mA, 28 V clamping voltage (VC) at 14.21 A peak pulse current, and ±30 kV IEC 61000-4-2 ESD immunity - deployed in automotive infotainment power rails and USB-C port protection.
For engineers reviewing the VTVS17GSMF-HM3-18 datasheet, VTVS17GSMF-HM3-18 pinout, VTVS17GSMF-HM3-18 application, or VTVS17GSMF-HM3-18 equivalent, key selection criteria include its ±2 % VBR tolerance, 606 pF capacitance at 0 V, AEC-Q101 qualification status, halogen-free construction, and compatibility with SOD-123W footprint for space-constrained PCB layouts.
Technical Context
This device operates as a unidirectional avalanche diode, triggering when reverse voltage exceeds its precisely specified breakdown range (19.6–20.4 V). Its low-clamping performance (28 V at 14.21 A, 10/1000 μs) limits transient-induced overvoltage stress on downstream ICs like USB transceivers or CAN controllers.
The SMF package enables wave and reflow soldering with MSL level 1 moisture sensitivity, peak temperature rating up to 260 °C, and thermal resistance of 20 K/W (junction-to-lead, infinite heat sink). Its "Low-Noise" technology ensures sub-nanosecond response time critical for protecting high-speed interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 400 W (10/1000 μs waveform; sustains repeated surges without degradation) |
| Stand-off Voltage (VRWM) | 16.9 V (maximum continuous reverse operating voltage before leakage exceeds 0.05 μA) |

IC Role / Device Role / Timing Role: First-line transient suppressor on main DC input, mounted near connector to minimize inductance. Use Value: Low 606 pF capacitance avoids signal distortion on adjacent data lines; AEC-Q101 qualification adds reliability confidence for commercial deployment. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ17A | ±5 % VBR tolerance (17.1–18.9 V), 600 W Pppm, SMA package (DO-214AC), 1.27 mm height | Higher power but larger footprint; less precise clamping threshold | Select when higher surge margin is needed and board space permits larger package |
| TPSMD17C | ±5 % VBR (17.1–18.9 V), 1500 W Pppm, SMC package (DO-214AB), 2.62 mm height | Triple the peak power rating but incompatible with SOD-123W layout; requires PCB redesign | Choose for severe industrial surge environments where 400 W is insufficient |
Compared with SMAJ17A and TPSMD17C, VTVS17GSMF-HM3-18 offers tighter ±2 % VBR control and SOD-123W footprint compatibility - enabling direct replacement in space-constrained automotive designs without sacrificing ESD robustness or thermal performance.

FAQ
What is the clamping voltage of VTVS17GSMF-HM3-18 at its rated peak pulse current?
The VTVS17GSMF-HM3-18 has a maximum reverse clamping voltage (VC) of 28 V at its rated peak pulse current (IPPM) of 14.21 A under 10/1000 μs waveform conditions. This value is measured per standard test conditions and defines the upper voltage limit imposed on protected circuitry during transient events. The VTVS17GSMF-HM3-18 maintains this clamping performance across its full operating temperature range of −55 °C to +175 °C.
Is VTVS17GSMF-HM3-18 qualified to AEC-Q101?
Yes, VTVS17GSMF-HM3-18 is AEC-Q101 qualified, confirming its suitability for automotive applications including powertrain, body electronics, and infotainment systems. This qualification covers stress tests such as high-temperature operating life, temperature cycling, and ESD robustness. The VTVS17GSMF-HM3-18 meets all required failure criteria per AEC-Q101 Rev D, and its qualification status is documented in Vishay's official product release and compliance reports.
What does the "HM3-18" suffix indicate in VTVS17GSMF-HM3-18?
The "HM3-18" suffix in VTVS17GSMF-HM3-18 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-down configuration per Vishay SMF carrier tape specification). This matches the ordering convention defined in Vishay document 85891, ensuring correct procurement and assembly alignment with SMT pick-and-place equipment.
Can VTVS17GSMF-HM3-18 be used in bidirectional signal lines?
No, VTVS17GSMF-HM3-18 is a unidirectional TVS diode and must only be used on DC power lines or single-polarity signal paths. Its anode-cathode polarity is fixed: cathode connects to the protected line, anode to ground. For bidirectional data lines like RS-485 or CAN, a dedicated bidirectional TVS (e.g., VTVS17B) or dual-diode array is required. Using VTVS17GSMF-HM3-18 on AC or bidirectional signals risks forward conduction and malfunction.
What is the thermal resistance junction-to-lead for VTVS17GSMF-HM3-18?
The thermal resistance junction-to-lead (RthJL) for VTVS17GSMF-HM3-18 is 20 K/W when mounted on an infinite heat sink, as specified in Vishay's absolute maximum ratings table. This value reflects the device's ability to conduct heat from the silicon junction to the PCB copper via the leads under ideal thermal conditions. Real-world RthJA will vary based on PCB copper area and layer stack-up, but RthJL remains a key parameter for estimating junction temperature rise during repetitive pulse operation.
