Product details
Overview
DG3002DB-T1-E1 from Vishay Siliconix is a low-voltage, single-pole single-throw (SPST) analog switch in MICRO FOOT® chip-scale package (1 mm × 1.5 mm, 6-bump), featuring 0.4 Ω on-resistance, 47 ns turn-on time, and 1.8 V to 5.5 V supply operation. It enables high-fidelity signal routing in space-constrained portable systems such as cellular handsets and battery-powered test equipment.
For engineers reviewing the DG3002DB-T1-E1 datasheet, DG3002DB-T1-E1 pinout, DG3002DB-T1-E1 application, or DG3002DB-T1-E1 equivalent, key selection considerations include its sub-Ω RON, fast switching performance at 1.8 V logic, ultra-small footprint compatibility with fine-pitch PCB layouts, and Pb-free Sn/Ag/Cu bump termination for RoHS-compliant assembly.
Technical Context
The DG3002DB-T1-E1 implements a monolithic CMOS SPST switch architecture built on Vishay's low-voltage JI2 process with epitaxial latchup protection. It supports bidirectional analog conduction when enabled and blocks signals up to the supply rail when off.
Its digital control interface accepts TTL/CMOS-compatible input levels (VINH ≥ 2 V, VINL ≤ 0.4 V at V+ = 3 V), while maintaining low dynamic power consumption (I+ ≤ 1 µA) and minimal charge injection (64 pC) - critical for precision sampling and low-distortion signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | SPST (normally open), single-channel analog switch |
| On-Resistance (RON) | 0.4 Ω typical at V+ = 2.7 V, VCOM = 1.5 V - ensures minimal signal attenuation and voltage drop in low-voltage sensor or audio paths |
| Turn-On/Off Time | tON = 47 ns, tOFF = 40 ns at V+ = 3 V - supports high-speed multiplexing in data acquisition and communication interfaces |
| Supply Voltage Range | 1.8 V to 5.5 V - compatible with modern low-power microcontrollers and battery-operated systems down to single-cell Li-ion or alkaline |
| Charge Injection | 64 pC - limits output voltage glitch during switching, preserving accuracy in sample-and-hold and ADC front-end circuits |
| Off-Isolation | –70 dB at 100 kHz - provides strong channel-to-channel signal rejection in multi-source analog routing |
| Package | MICRO FOOT® (6-bump, 3 × 2 array, 0.5 mm pitch, 1.49 mm × 0.99 mm body) - reduces PCB area by >80% vs. SOIC-8, ideal for ultra-thin mobile designs |
Pinout & Package
MICRO FOOT® package: 6-bump, 3 × 2 array, 0.5 mm pitch, Pb-free Sn/Ag/Cu bumps (238 µm nominal height), marked "3002" on die back with date/lot code. Dimensions: 1.49 mm × 0.99 mm × 0.688 mm (max height).
| 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 for analog and digital circuitry; bypass with 100 nF ceramic capacitor near package |
| A3 | Control Input (IN) | Active-high digital enable; drives internal CMOS gate; compatible with 1.8 V/3.3 V logic |
| B1 | Normally Open (NO) | Analog terminal disconnected from COM when IN = 0; connects to COM when IN = 1 |
| B2 | Common (COM) | Signal path center node; bidirectional conduction with matched RON in both directions |
| B3 | No Connect (NC) | Internally unconnected bump; must remain floating - no PCB trace or solder mask opening required |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low on-resistance | 0.4 Ω typical enables <1 mV drop at 2.5 mA - preserves signal integrity in precision sensor interfaces |
| MICRO FOOT® chip-scale packaging | 1.49 mm × 0.99 mm footprint saves >80% board area vs. SOIC-8 - critical for PDA and smartphone module density |
| Low-voltage operation | Functional down to 1.8 V supply allows direct interfacing with advanced low-power MCUs without level-shifting |
| Fast switching with low charge injection | 47 ns tON and 64 pC QINJ support clean multiplexing in 10-bit+ ADC sampling and audio routing |
| Latchup-immune process | JI2 CMOS with epitaxial layer prevents destructive latchup - enhances reliability in noisy battery-powered environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Texas Instruments TS5A23157DCUR | 0.9 Ω RON, 10-bit logic-compatible, same 6-pin UQFN (1.6 mm × 1.6 mm) | Larger footprint (+13% area), higher RON increases voltage drop in 1.8 V sensor paths | Preferred where higher ESD rating (±2 kV HBM) and broader temp range (–40 °C to 125 °C) are required |
| Analog Devices ADG801BRMZ-REEL7 | 0.3 Ω RON, 1.8 V–5.5 V, 6-pin SOT-23 package (2.9 mm × 1.6 mm) | 3× larger PCB footprint; requires rework of land pattern and stencil design | Chosen when legacy SMT assembly lines lack MICRO FOOT® reflow capability or underfill-free handling experience |
Compared with DG3002DB-T1-E1, TS5A23157DCUR offers better ESD robustness but sacrifices 0.5 Ω RON and adds 0.11 mm² area; ADG801BRMZ-REEL7 delivers lower RON yet demands significant layout revision due to SOT-23 size - making DG3002DB-T1-E1 optimal for new ultra-compact designs prioritizing board space and low-voltage fidelity.

FAQ
Is DG3002DB-T1-E1 still in production?
No - DG3002DB-T1-E1 is officially End of Life per Vishay document 72505 (Rev. D, Feb 2011). Aetrix Electronics maintains limited legacy stock with full traceability and supports last-time buys for ongoing production continuity. No new manufacturing runs are scheduled.
What does the "-E1" suffix mean in DG3002DB-T1-E1?
The "-E1" suffix on DG3002DB-T1-E1 indicates lead-free termination using Sn/Ag/Cu solder bumps (238 µm nominal height), compliant with RoHS Directive 2011/65/EU. It replaces the eutectic Sn/Pb version (DG3002DB-T1) and requires a higher reflow peak temperature (250 °C).
Can DG3002DB-T1-E1 operate reliably at 1.8 V supply?
Yes - DG3002DB-T1-E1 is fully specified from 1.8 V to 5.5 V. At V+ = 1.8 V, RON rises to ~0.8 Ω (max), tON extends to ~71 ns, and logic thresholds scale proportionally (VINH ≥ 1.2 V), all verified across –40 °C to +85 °C per datasheet Section 3.
How is the NC (No Connect) bump handled in PCB layout for DG3002DB-T1-E1?
The B3 bump on DG3002DB-T1-E1 is internally unconnected and must remain electrically floating. Per Vishay AN824 guidelines, no copper pad, solder mask opening, or trace should be assigned to this location - omitting it avoids unintended parasitic coupling or solder bridging in fine-pitch assembly.
Does DG3002DB-T1-E1 support bidirectional analog signal flow?
Yes - DG3002DB-T1-E1 conducts equally well in both directions when ON, with symmetrical RON flatness (0.2 Ω max variation) and matched leakage (<±10 nA). This enables flexible use in transducer interfaces, audio paths, and sensor excitation circuits without polarity constraints.
