Product details
Overview
VTVS15GSMF-HM3-08 from Vishay Semiconductors is a unidirectional 400 W TransZorb® transient voltage suppressor diode in SMF (DO-219AB) package, designed for ESD and surge protection of low-voltage DC lines. It features 15.1 V maximum stand-off voltage (VRWM), 17.6–18.31 V reverse breakdown voltage (VBR) at 1 mA, 25 V clamping voltage (VC) at 15.89 A peak pulse current, and ±30 kV IEC 61000-4-2 ESD immunity - deployed in automotive infotainment power rails and USB Type-C port protection.
For engineers reviewing the VTVS15GSMF-HM3-08 datasheet, VTVS15GSMF-HM3-08 pinout, VTVS15GSMF-HM3-08 application, or VTVS15GSMF-HM3-08 equivalent, key selection criteria include its ±2 % VBR tolerance, 684 pF capacitance at 0 V, 175 °C max junction temperature, halogen-free construction, and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
This device operates as a unidirectional avalanche diode, triggering when reverse voltage exceeds its precisely specified breakdown range (17.6–18.31 V). Its low-clamping behavior (25 V at 15.89 A, 10/1000 μs) limits transient energy dissipation across protected ICs while maintaining low leakage (<0.05 μA at VRWM).
The SMF package enables high-density PCB layout with wave/reef solder compatibility, MSL level 1 moisture sensitivity, and UL 94 V-0 flammability rating. Its "Low-Noise" technology ensures sub-nanosecond response time, critical for protecting high-speed interfaces without signal distortion.
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) | 15.1 V (maximum continuous reverse voltage before significant leakage) |
| Breakdown Voltage (VBR) | 17.6–18.31 V at IT = 1 mA (±2 % tolerance ensures tight clamping threshold control) |
| Clamping Voltage (VC) | 25 V at IPPM = 15.89 A (limits voltage seen by downstream circuitry during surge) |
| Capacitance (CD) | 684 pF at VR = 0 V, f = 1 MHz (suitable for <10 Mbps data lines; not for USB 3.0+) |
| ESD Rating | ±30 kV contact / ±30 kV air (IEC 61000-4-2 Level 4; eliminates need for external ESD staging) |
| Junction Temp. Range | −55 °C to +175 °C (supports under-hood automotive and industrial ambient conditions) |

Applications
| Automotive Infotainment Power Rail Protection | USB Type-C VBUS Line Protection |
|---|---|
|
Use Scenario: Protecting 12 V supply rails feeding head unit processors and display drivers against load dump and ISO 7637-2 transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between VBAT and local regulator input to clamp surges before LDO/DC-DC stage. Use Value: Withstands 400 W pulses and operates up to 175 °C, eliminating thermal runaway risk in sealed enclosures. |
Use Scenario: Safeguarding USB Type-C receptacle VBUS pins against hot-plug surges and ESD events during cable insertion. IC Role / Device Role / Timing Role: Standoff-rated TVS connected between VBUS and chassis ground to shunt transients before USB controller power input. Use Value: 15.1 V VRWM avoids false triggering during 5 V ±5 % nominal operation; 684 pF capacitance preserves signal integrity on 480 Mbps USB 2.0 links. |
| Industrial Sensor Interface Protection | Automotive LIN Bus Node Protection |
|
Use Scenario: Shielding analog sensor outputs (e.g., pressure, temperature) from induced transients in factory automation wiring harnesses. IC Role / Device Role / Timing Role: Low-leakage TVS placed across differential pair or single-ended output to suppress common-mode surges. Use Value: Sub-0.05 μA IR at VRWM prevents loading of high-impedance sensor outputs; 25 V VC limits excursion into ADC input range. |
Use Scenario: Protecting LIN transceiver pins against battery disconnect spikes and electrostatic discharge in door module ECUs. IC Role / Device Role / Timing Role: Unidirectional TVS tied between LIN bus line and ground to clamp negative-going transients without affecting dominant/recessive signaling. Use Value: AEC-Q101 qualification ensures reliability over 15-year vehicle lifetime; DO-219AB package withstands mechanical vibration per LV-124. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A-E3/57T | ±5 % VBR tolerance (16.7–18.5 V), 200 W PPPM, SMA package (DO-214AC) | Lower power rating and looser voltage tolerance; larger footprint than SMF | Select when cost sensitivity outweighs space constraints and AEC-Q101 is not required |
| TPSMD15A | ±5 % VBR (16.7–18.5 V), 400 W PPPM, same SMF package, but no AEC-Q101 qualification | Lacks automotive qualification; identical electrical specs and footprint | Choose for industrial or consumer designs where automotive reliability validation is unnecessary |
Compared with VTVS15GSMF-HM3-08, SMAJ15A-E3/57T offers lower surge robustness and less precise clamping, while TPSMD15A matches power and form factor but omits AEC-Q101 validation - making VTVS15GSMF-HM3-08 the only option meeting full automotive qualification with ±2 % tolerance in SMF.

FAQ
What is the clamping voltage of the VTVS15GSMF-HM3-08 under a 10/1000 μs surge?
The VTVS15GSMF-HM3-08 has a maximum reverse clamping voltage (VC) of 25 V at 15.89 A peak pulse current with a 10/1000 μs waveform. This value is measured per standard test conditions and defines the upper voltage limit imposed on protected circuitry during transient events. The VTVS15GSMF-HM3-08 maintains this clamping performance across its full operating temperature range (−55 °C to +175 °C).
Is VTVS15GSMF-HM3-08 qualified for automotive use?
Yes, the VTVS15GSMF-HM3-08 is AEC-Q101 qualified, meaning it has passed stress tests for temperature cycling, humidity, mechanical shock, and high-temperature operating life required for automotive electronic components. This qualification applies specifically to the VTVS15GSMF-HM3-08 variant and confirms suitability for under-hood and cabin applications including infotainment, body control, and LIN/CAN node protection.
What does the "HM3-08" suffix indicate in VTVS15GSMF-HM3-08?
The "HM3-08" suffix denotes halogen-free (H), lead-free (M), and 3 k per 7″ reel packaging (3), with "-08" specifying tape-and-reel format using 8 mm carrier tape. This coding aligns with Vishay's standardized ordering nomenclature and confirms RoHS compliance, halogen-free molding compound, and standard SMT handling configuration for the VTVS15GSMF-HM3-08.
Can VTVS15GSMF-HM3-08 be used for bidirectional protection?
No, the VTVS15GSMF-HM3-08 is a unidirectional TVS diode, intended only for circuits where polarity is fixed and transients occur in one direction relative to ground. It must be oriented with cathode toward the protected line and anode to ground. For bidirectional protection (e.g., AC lines or differential buses), a dedicated bidirectional TVS such as VTVS15BGSMSF would be required - the VTVS15GSMF-HM3-08 does not support symmetrical clamping.
What is the thermal resistance (RthJL) of VTVS15GSMF-HM3-08?
The thermal resistance from junction to lead (RthJL) of the VTVS15GSMF-HM3-08 is 20 K/W when mounted on an infinite heat sink. This parameter determines how effectively heat generated during surge conduction transfers from the silicon die to the PCB copper or heatsink. Designers should ensure adequate copper area and thermal vias beneath the SMF package to maintain safe junction temperatures below 175 °C during repetitive 400 W pulses.
