Product details
Overview
VTVS63GSMF-HM3-08 from Vishay Semiconductors is a unidirectional 400 W TransZorb® transient voltage suppressor diode in SMF (DO-219AB) package, with 63 V stand-off voltage (VRWM), ±2 % breakdown voltage tolerance, 108 A peak pulse current (IPPM), and 108 V maximum clamping voltage (VC) at IPPM - designed for ESD and surge protection of automotive power lines and industrial DC inputs.
For engineers reviewing the VTVS63GSMF-HM3-08 datasheet, VTVS63GSMF-HM3-08 pinout, VTVS63GSMF-HM3-08 application, or VTVS63GSMF-HM3-08 equivalent, this part delivers precise clamping performance, AEC-Q101 qualification, halogen-free construction, and compatibility with SOD-123W footprint - critical for high-reliability 12 V/24 V/48 V system protection where low leakage (<0.05 μA) and fast response are required.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, triggered when reverse voltage exceeds its 73.01–75.99 V breakdown range (VBR) at IT = 1 mA. Its 108 V clamping voltage at 10/1000 μs waveform ensures robust protection of downstream MOSFETs and controllers during ISO 7637-2 pulse 1/2a/5a transients.
The device features IEC 61000-4-2 ±30 kV contact/air discharge immunity and thermal resistance RthJL = 20 K/W, enabling reliable operation up to TJ = +175 °C in compact PCB layouts. Its 1.08 mm height and DO-219AB outline support automated assembly without reflow risk.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VRWM) | 63 V - maximum continuous reverse operating voltage before clamping begins; matches 48 V nominal bus systems with margin. |
| Breakdown Voltage (VBR) | 73.01–75.99 V at IT = 1 mA, ±2 % tolerance - tight regulation enables predictable trigger point across temperature. |
| Peak Pulse Power (PPP) | 400 W at 10/1000 μs - sustains high-energy surges common in automotive load-dump and inductive switching events. |
| Clamping Voltage (VC) | 108 V at IPPM = 108 A - limits voltage seen by protected ICs to safe levels under worst-case transient conditions. |
| Leakage Current (IR) | <0.05 μA at VRWM - negligible standby power loss and no signal integrity impact on high-impedance sensing nodes. |
| Capacitance (CD) | 227 pF at VR = 0 V, f = 1 MHz - suitable for DC power rails; low enough to avoid resonance with typical bulk capacitance. |
| ESD Rating | ±30 kV contact / ±30 kV air per IEC 61000-4-2 - meets stringent automotive and industrial ESD immunity requirements. |
| Junction Temp Range | −55 °C to +175 °C - supports under-hood and industrial control cabinet deployment without derating. |

Its standardized tape-and-reel packaging (8 mm carrier tape, 3K per 7″ reel) and MSL level 1 rating ensure seamless integration into automated SMT lines. The VTVS63GSMF-HM3-08 is fully wave and reflow solderable per J-STD-020.
How does the ±2 % breakdown voltage tolerance of the VTVS63GSMF-HM3-08 benefit circuit design?
The ±2 % VBR tolerance of the VTVS63GSMF-HM3-08 allows tighter coordination with downstream overvoltage protection thresholds - reducing unnecessary design margin and enabling more efficient use of voltage headroom in 48 V systems. This precision improves system-level surge immunity predictability versus ±5 % variants. The VTVS63GSMF-HM3-08 maintains this tolerance across its full operating temperature range.
