Product details
Overview
DG3001DB-T1-E1 from Vishay Siliconix is a low-voltage, sub-ohm SPST analog switch in MICRO FOOT® chip-scale package (1 mm × 1.5 mm, 6-bump), operating from 1.8 V to 5.5 V with 0.4 Ω on-resistance, 47 ns turn-on time, and TTL/CMOS-compatible control - used for signal routing in portable battery-powered systems such as cellular handsets and PDAs.
For engineers reviewing the DG3001DB-T1-E1 datasheet, DG3001DB-T1-E1 pinout, DG3001DB-T1-E1 application, or DG3001DB-T1-E1 equivalent, key selection criteria include its ultra-small footprint, low RON stability over voltage/temperature, charge injection (64 pC), off-isolation (–70 dB), and Pb-free Sn/Ag/Cu bump termination.
Technical Context
The DG3001DB-T1-E1 implements a monolithic CMOS SPST switch fabricated on Vishay's low-voltage JI2 process with epitaxial latchup protection. It supports bidirectional analog conduction when on and blocks signals up to the supply rail when off.
Its digital control interface accepts 0.4 V low and 2 V high logic thresholds across –40 °C to +85 °C, while dynamic performance is characterized at V+ = 3 V, RL = 300 Ω, and CL = 35 pF - delivering tON = 47 ns and tOFF = 40 ns with 1 ns break-before-make interval.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Single-pole single-throw (SPST), normally open (NO) configuration |
| On-Resistance (RON) | 0.4 Ω typical at V+ = 2.7 V, VCOM = 1.5 V - enables minimal signal attenuation in precision analog paths |
| Supply Voltage Range | 1.8 V to 5.5 V - compatible with modern low-power microcontrollers and I/O rails |
| Turn-On / Turn-Off Time | 47 ns / 40 ns at V+ = 3 V - supports high-speed multiplexing in data acquisition and audio switching |
| Charge Injection | 64 pC - limits voltage glitch on high-impedance nodes during switching transitions |
| Off-Isolation | –70 dB at 100 kHz - ensures strong channel-to-channel signal rejection in multi-channel systems |
| Input Logic Compatibility | TTL/CMOS - simplifies interface with standard digital controllers without level-shifting |
Pinout & Package
MICRO FOOT® 6-bump chip-scale package (3 × 2 array, 0.5 mm pitch), Pb-free Sn/Ag/Cu bumps, 1.49 mm × 0.99 mm body, 0.688–0.753 mm height, laser-marked die back with "3001" device code and traceability code.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Ground (GND) | Reference node for logic and analog sections; must be low-impedance connection to PCB ground plane |
| A2 | Positive Supply (V+) | Power rail input; decoupling capacitor required within 2 mm for stable switching performance |
| A3 | Control Input (IN) | Active-high digital enable; drives internal CMOS transmission gate when ≥2 V |
| B1 | Normally Open (NO) | Analog output terminal; connects to COM when IN = high |
| B2 | Common (COM) | Central analog path; bidirectional conduction with NO or NC depending on variant |
| B3 | No Connect (NC) | Internally unconnected bump; must remain floating per datasheet - no PCB trace or pad connection |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-compact footprint | 1.0 mm × 1.5 mm area - reduces PCB real estate by >80% vs. comparable TSSOP-6 switches |
| Sub-ohm on-resistance | 0.4 Ω typical - preserves signal integrity in low-voltage sensor and audio signal chains |
| Low charge injection | 64 pC - minimizes settling error in sample-and-hold and ADC front-end applications |
| Pb-free termination | Sn/Ag/Cu bumps with "-E1" suffix - RoHS-compliant and qualified for lead-free reflow (250 °C peak) |
| Latchup immunity | Epitaxial layer isolation - eliminates risk of destructive latchup under transient overvoltage conditions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617EUT+T | SPST, 0.6 Ω RON, 30 ns tON, SOT-23-6 package (2.9 mm × 1.6 mm) | Larger footprint, higher RON, faster switching - suited for non-space-constrained industrial designs | Select when board area is less critical than switching speed and wider V+ range (2.7 V to 12 V) |
| ADG801BRMZ-REEL7 | SPST, 0.3 Ω RON, 25 ns tON, 1.6 mm × 1.6 mm 6-pin LFCSP | Slightly larger footprint, lower RON, faster switching, different pinout - requires layout revision | Choose for highest analog fidelity where 0.3 Ω RON and 25 ns tON justify redesign effort and cost premium |
Compared with MAX4617EUT+T and ADG801BRMZ-REEL7, the DG3001DB-T1-E1 offers the smallest footprint (1.0 × 1.5 mm) and lowest profile among alternatives, making it optimal for ultra-thin portable devices - though its 47 ns switching speed and 0.4 Ω RON sit between those two options.

FAQ
What is the maximum continuous current rating for DG3001DB-T1-E1?
The DG3001DB-T1-E1 supports ±250 mA continuous current through its NO, NC, or COM terminals at TA = 25 °C. Derating applies above 70 °C (3.1 mW/°C), and peak pulsed current is ±400 mA at 1 ms pulse width and 10% duty cycle. These ratings assume proper PCB thermal design with adequate copper pour under the MICRO FOOT bumps.
Does DG3001DB-T1-E1 support bidirectional analog signal switching?
Yes, DG3001DB-T1-E1 conducts equally well in both directions when ON, as confirmed in the datasheet description: "Each switch conducts equally well in both directions when on, and blocks up to the power supply level when off." This makes it suitable for AC-coupled audio, sensor, and data line applications without polarity constraints.
What does the "-E1" suffix indicate in DG3001DB-T1-E1?
Per Vishay documentation, the "-E1" suffix denotes Pb-free termination using Sn/Ag/Cu solder bumps, distinguishing it from eutectic Sn/Pb versions (e.g., DG3001DB-T1). It complies with RoHS Directive 2011/65/EU and is qualified for lead-free reflow profiles with 250 °C peak temperature.
Is DG3001DB-T1-E1 still in active production?
No - the official Vishay datasheet (Rev. D, 28-Feb-11) explicitly states "Product is End of Life." However, Aetrix Electronics maintains limited legacy inventory and supports continuity planning, including obsolescence forecasting and cross-reference guidance for functional replacements.
How is the NC pin (B3) handled in DG3001DB-T1-E1 layout?
The NC pin (B3) in DG3001DB-T1-E1 is internally unconnected and must remain floating - no PCB trace, pad, or solder connection is permitted. The datasheet specifies this in the pin configuration diagram and notes that connecting it may compromise reliability or electrical performance due to parasitic coupling.
