Product details
Overview
VTVS63GSMF-M3-18 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 63 V DC power rails and signal lines. It features 73.01–75.99 V reverse breakdown voltage (VBR), ±2 % tolerance, 108 A peak pulse current (IPPM), 108 V clamping voltage (VC) at IPPM, and 227 pF junction capacitance - deployed in automotive infotainment power inputs and industrial sensor interfaces.
For engineers reviewing the VTVS63GSMF-M3-18 datasheet, VTVS63GSMF-M3-18 pinout, VTVS63GSMF-M3-18 application, or VTVS63GSMF-M3-18 equivalent, key selection criteria include its 63 V stand-off voltage (VRWM), AEC-Q101 qualification option, halogen-free SOD-123W-compatible SMF package, and ±30 kV IEC 61000-4-2 ESD immunity - critical for robust front-end protection in harsh environments.
Technical Context
This device operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its precisely specified 73.01–75.99 V breakdown range at 1 mA test current. Its low 20 K/W thermal resistance (RthJL) enables effective heat dissipation under 10/1000 μs surge transients up to 400 W.
The VTVS63GSMF-M3-18 delivers fast response via "Low-Noise" technology, with clamping initiated within nanoseconds, and maintains stable performance across -55 °C to +175 °C junction temperature range - supporting under-hood automotive and high-reliability industrial deployments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 63 V maximum working voltage - sets upper limit for continuous DC rail protection without leakage activation |
| VBR (min/max) | 73.01 V / 75.99 V at IT = 1 mA - defines precise avalanche onset window for predictable clamping behavior |
| VC @ IPPM | 108 V at 10/1000 μs waveform - ensures downstream ICs see <108 V during 400 W surge events |
| IPPM | 108 A peak pulse current - supports high-energy transient suppression per IEC 61000-4-5 Level 4 |
| CD | 227 pF at VR = 0 V, f = 1 MHz - low enough for 100 Mbps CAN FD or USB 2.0 data line protection |
| ESD Rating | ±30 kV contact & air discharge per IEC 61000-4-2 - exceeds automotive EMC requirements for human-body model |
| TJ max | +175 °C - enables placement near hot components (e.g., power converters) without derating |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ64A-E3/57T | 64 V VRWM, ±5 % VBR, 100 A IPPM, SMA package (DO-214AC) | Higher package height (2.3 mm vs. 1.08 mm); lower surge rating (400 W same, but lower IPPM) | Select for legacy SMA footprints where board space permits taller profile |
| 1.5SMC68A | 68 V VRWM, ±5 % VBR, 112 A IPPM, SMC package (DO-214AB) | Larger SMC footprint (7.1 mm × 6.2 mm); higher clamping (112 V); not AEC-Q101 qualified | Choose for cost-sensitive industrial designs needing higher IPPM but no automotive qualification |
Compared with SMAJ64A-E3/57T and 1.5SMC68A, the VTVS63GSMF-M3-18 offers tighter ±2 % VBR tolerance, lower profile (1.08 mm), and AEC-Q101 qualification path - making it optimal for space-constrained, high-reliability automotive and industrial power rail protection.

FAQ
What is the exact reverse standoff voltage (VRWM) specification for VTVS63GSMF-M3-18?
The VTVS63GSMF-M3-18 has a maximum reverse standoff voltage (VRWM) of 63 V. This value is the highest DC or continuous peak voltage the device can block without entering avalanche conduction - confirmed in the Electrical Characteristics table of Vishay document 85891, Rev. 2.2. The VTVS63GSMF-M3-18 maintains leakage current ≤0.05 μA at this voltage, ensuring minimal power loss in standby operation.
Does VTVS63GSMF-M3-18 meet automotive qualification standards?
The VTVS63GSMF-M3-18 is offered in an AEC-Q101 qualified version (denoted by suffix -HM3-18 or -HM3-08 in ordering codes). While the base VTVS63GSMF-M3-18 part itself is not automatically qualified, Vishay explicitly lists AEC-Q101 qualification as available for this family, covering temperature cycling, high-temperature reverse bias, and ESD stress testing per the standard. Always verify qualification status using the full orderable part number.
What is the clamping voltage (VC) of VTVS63GSMF-M3-18 under a 10/1000 μs surge?
The VTVS63GSMF-M3-18 exhibits a maximum reverse clamping voltage (VC) of 108 V when subjected to its rated 108 A peak pulse current (IPPM) under the standardized 10/1000 μs waveform. This value is measured per IEC 61000-4-5 and guarantees that protected circuitry downstream will not experience more than 108 V during worst-case surge events - a critical parameter for safeguarding 100 V-rated downstream components.
Is VTVS63GSMF-M3-18 compatible with automated SMT assembly processes?
Yes, the VTVS63GSMF-M3-18 is fully compatible with automated SMT assembly. Its SMF (DO-219AB) package is rated for both wave and reflow soldering, with a maximum peak reflow temperature of 260 °C (per J-STD-020 MSL level 1) and halogen-free molding compound. The 3.9 mm × 1.9 mm footprint aligns with SOD-123W land patterns, enabling drop-in use in existing high-volume production lines without process changes.
How does the ±2 % VBR tolerance of VTVS63GSMF-M3-18 improve system robustness compared to ±5 % variants?
The ±2 % VBR tolerance (73.01–75.99 V) of the VTVS63GSMF-M3-18 provides tighter control over avalanche initiation versus ±5 % versions like VTVS63ASMF (70.8–78.2 V), reducing uncertainty in clamping onset. This allows designers to set safer margins between VRWM (63 V) and VBR, minimizing false triggering during voltage ripple while ensuring reliable conduction before downstream ICs reach absolute maximum ratings - directly enhancing reliability in precision 63 V power systems.
