Product details
Overview
VTVS17ASMF-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 a 16.9 V maximum stand-off voltage (VRWM), 19.0–21.0 V reverse breakdown voltage (VBR) at 1 mA, 28 V clamping voltage (VC) at 13.79 A peak pulse current, and ±30 kV IEC 61000-4-2 ESD immunity-used in automotive infotainment power rails and industrial sensor interfaces.
For engineers reviewing the VTVS17ASMF-HM3-08 datasheet, VTVS17ASMF-HM3-08 pinout, VTVS17ASMF-HM3-08 application, or VTVS17ASMF-HM3-08 equivalent, key selection criteria include clamping performance under 10/1000 μs surge, unidirectional polarity compatibility with positive-rail protection schemes, halogen-free SOD-123W-compatible packaging, and AEC-Q101 qualification status per ordering code suffix.
Technical Context
This TVS diode operates as a unidirectional shunt protector, triggering into avalanche conduction when reverse voltage exceeds its 19.0–21.0 V breakdown range. Its low 20 K/W thermal resistance (RthJL) enables effective heat dissipation during 400 W peak pulse events, while sub-1 ns response time ensures suppression before downstream IC damage occurs.
The device complies with IEC 61000-4-2 (±30 kV contact/air discharge) and supports reflow/wave soldering per J-STD-020 MSL level 1. Its 606 pF capacitance at 0 V bias makes it suitable for signal-line protection where bandwidth preservation is secondary to robustness.
Key Specifications

FAQ
What is the clamping voltage of VTVS17ASMF-HM3-08 under maximum surge conditions?
The VTVS17ASMF-HM3-08 exhibits a maximum reverse clamping voltage (VC) of 28 V when subjected to its rated peak pulse current of 13.79 A using a 10/1000 μs waveform. This value is measured at the device terminals and defines the upper voltage limit imposed on the protected circuit during transient events, ensuring downstream ICs remain within safe operating margins.
Is VTVS17ASMF-HM3-08 qualified to AEC-Q101 standards?
Yes, VTVS17ASMF-HM3-08 is AEC-Q101 qualified. The "H" in the ordering code explicitly denotes halogen-free construction and AEC-Q101 qualification, verified per Vishay's qualification report for the VTVS eSMP® Series. This makes VTVS17ASMF-HM3-08 suitable for automotive powertrain, body electronics, and infotainment applications requiring stress-tested reliability.
What does the "-HM3-08" suffix indicate in VTVS17ASMF-HM3-08?
The "-HM3-08" suffix encodes three critical attributes: "H" = AEC-Q101 qualified and halogen-free; "M3" = lead (Pb)-free, tin-plated terminations; "-08" = 3000 units per 7-inch reel (8 mm tape, minimum order quantity 30 k). This full ordering code ensures traceable compliance with RoHS, ELV, and automotive environmental requirements.
Can VTVS17ASMF-HM3-08 be used in bidirectional protection configurations?
No, VTVS17ASMF-HM3-08 is a unidirectional TVS diode and must be used with correct polarity-cathode toward the protected line, anode to ground. For bidirectional protection, two VTVS17ASMF-HM3-08 devices would need back-to-back configuration, or a dedicated bidirectional part like VTVS17BSMF-HM3-08 should be selected instead.
What is the thermal resistance junction-to-lead (RthJL) for VTVS17ASMF-HM3-08?
The thermal resistance junction-to-lead (RthJL) for VTVS17ASMF-HM3-08 is 20 K/W when mounted on an infinite heat sink. This parameter quantifies how effectively heat generated during 400 W transient events transfers from the silicon junction to the PCB copper leads, directly influencing safe surge repetition rate and long-term reliability in thermally constrained layouts.
