Product details
Overview
VTVS17GSMF-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 on low-voltage DC lines such as USB, HDMI, and automotive sensor interfaces. It features 16.9 V stand-off voltage (VRWM), 19.6–20.4 V reverse breakdown (VBR), 28 V clamping voltage (VC) at 14.21 A peak pulse current (IPPM), and ±30 kV IEC 61000-4-2 ESD immunity.
For engineers reviewing the VTVS17GSMF-M3-08 datasheet, VTVS17GSMF-M3-08 pinout, VTVS17GSMF-M3-08 application, or VTVS17GSMF-M3-08 equivalent, key selection criteria include its ±2 % VBR tolerance, 606 pF capacitance at 0 V, 175 °C max junction temperature, and compatibility with SOD-123W footprint - critical for high-reliability automotive and industrial interface protection.
Technical Context
This device operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its precisely specified 19.6–20.4 V breakdown range at 1 mA test current. Its low 28 V clamping voltage at 14.21 A (10/1000 μs waveform) ensures robust protection of downstream ICs without overvoltage stress.
The SMF package delivers thermal resistance of 20 K/W to leads and supports wave/reflow soldering per J-STD-020 MSL level 1, with peak reflow temperature up to 260 °C. Its halogen-free molding compound and AEC-Q101 qualification readiness align with automotive-grade reliability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VRWM) | 16.9 V - maximum continuous reverse operating voltage before conduction begins |
| Breakdown Voltage (VBR) | 19.6–20.4 V at IT = 1 mA - tight ±2 % tolerance enables precise overvoltage threshold control |
| Clamping Voltage (VC) | 28 V at IPPM = 14.21 A (10/1000 μs) - limits transient energy delivered to protected circuitry |
| Peak Pulse Power (PPP) | 400 W - sustains high-energy transients common in automotive load-dump or ESD events |
| Capacitance (CD) | 606 pF at VR = 0 V, f = 1 MHz - optimized for signal integrity in <100 Mbps data lines |
| ESD Rating | ±30 kV contact / ±30 kV air (IEC 61000-4-2) - exceeds Level 4 immunity for harsh environments |
| Junction Temperature Range | −55 °C to +175 °C - supports under-hood automotive and industrial ambient conditions |
Pinout & Package

| Halogen-free, RoHS-compliant | Meets automotive and industrial environmental compliance mandates without compromising thermal performance |
| AEC-Q101 qualification available | Supports automotive applications where component-level reliability validation is mandatory |
| Wave and reflow solderable | Compatible with standard SMT assembly processes, including lead-free reflow profiles up to 260 °C |
Applications
| Automotive Sensor Interface | USB 2.0 Data Line Protection |
|---|---|
Use Scenario: Protecting LIN bus or analog sensor outputs (e.g., pressure, temperature) in engine control modules exposed to ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional TVS placed between signal line and chassis ground to clamp induced transients. Use Value: 28 V clamping voltage prevents damage to 16 V-rated op-amps or ADC inputs while maintaining signal fidelity via 606 pF capacitance. |
Use Scenario: Safeguarding USB 2.0 D+ and D− lines against ESD events during hot-plug insertion in infotainment systems. IC Role / Device Role / Timing Role: Bidirectional protection not required; unidirectional VTVS17GSMF-M3-08 used per line with cathode to signal, anode to ground. Use Value: ±30 kV IEC 61000-4-2 rating meets USB-IF compliance; low capacitance avoids signal rise-time degradation at 480 Mbps. |
| Industrial CAN Bus Node | DC Power Input Protection |
Use Scenario: Secondary protection on CAN_H/CAN_L lines downstream of common-mode chokes in factory automation controllers. IC Role / Device Role / Timing Role: Standoff voltage (16.9 V) exceeds CAN recessive/common-mode range, enabling selective clamping only during overvoltage faults. Use Value: 400 W peak power rating handles repetitive surges from inductive switching noise without degradation. |
Use Scenario: Input-stage surge suppression for 24 V industrial PLC I/O modules subjected to IEC 61000-4-5 line-to-ground surges. IC Role / Device Role / Timing Role: Placed after fuse and upstream of DC-DC converter to absorb energy before regulation stage. Use Value: 175 °C max junction temperature allows operation in sealed enclosures; DO-219AB package withstands mechanical stress from board flexure. |
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 (16.2–17.8 V), higher 34.4 V clamping at 12.3 A, 500 pF capacitance | Less precise threshold control; higher VC may overstress 16 V-rated receivers | Select when cost sensitivity outweighs tight clamping or automotive qualification needs |
| SMCJ17A | Same ±5 % VBR but 1500 W rating, larger DO-214AB package (7.11 mm × 6.22 mm), 100 pF capacitance | Over-specified power for most interface protection; unsuitable for space-constrained layouts | Choose only when 1500 W surge handling is explicitly required and board area permits larger footprint |
Compared with SMAJ17A and SMCJ17A, VTVS17GSMF-M3-08 offers superior voltage precision (±2 % vs. ±5 %), lower clamping (28 V vs. ≥34.4 V), and optimal 606 pF capacitance for high-speed interfaces - making it the preferred choice for compact, high-reliability automotive and industrial signal-line protection.

FAQ
What is the exact breakdown voltage range for VTVS17GSMF-M3-08?
The VTVS17GSMF-M3-08 has a reverse breakdown voltage (VBR) range of 19.6 V to 20.4 V at IT = 1 mA and TJ = 25 °C, reflecting its ±2 % tolerance grade. This tight specification ensures consistent triggering behavior across production lots and temperature extremes, critical for protecting 16 V-rated circuits without false triggering.
Is VTVS17GSMF-M3-08 qualified to AEC-Q101?
VTVS17GSMF-M3-08 is part of Vishay's AEC-Q101-qualified eSMP® family; while the base part number does not carry the "-H" suffix indicating certified qualification, the underlying SMF platform and process are AEC-Q101 validated. Customers requiring full certification should specify VTVS17GSMF-HM3-08 for automotive production use.
What is the maximum clamping voltage of VTVS17GSMF-M3-08 under surge conditions?
The maximum reverse clamping voltage (VC) of VTVS17GSMF-M3-08 is 28 V at a peak pulse current (IPPM) of 14.21 A with a 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case transients, ensuring compatibility with 3.3 V, 5 V, and 16 V interface ICs.
Can VTVS17GSMF-M3-08 be used for bidirectional protection?
No - VTVS17GSMF-M3-08 is a unidirectional TVS diode, intended for DC lines with defined polarity. For bidirectional protection (e.g., AC-coupled or differential lines like RS-485), a dedicated bidirectional variant such as VTVS17BGS-M3-08 must be selected; using this unidirectional part in reverse-biased configurations risks permanent failure.
What is the thermal resistance and maximum junction temperature of VTVS17GSMF-M3-08?
VTVS17GSMF-M3-08 has a thermal resistance (RthJL) of 20 K/W to leads when mounted on an infinite heat sink, and a maximum junction temperature (TJ) of +175 °C. These ratings enable reliable operation in under-hood automotive environments and sealed industrial enclosures where ambient temperatures exceed 125 °C.
