Product details
Overview
DG300AAK from Vishay Siliconix is a hermetically sealed, military-grade SPST analog switch in a 10-pin metal can package, rated for -55 °C to +125 °C operation. It features dual-channel independent switching, ±15 V analog signal range, 30 Ω typical on-resistance, 150 ns turn-on time, and latch-up proof CMOS design-used in precision instrumentation signal routing where rail-to-rail analog integrity and high-reliability power cycling are required.
For engineers reviewing the DG300AAK datasheet, DG300AAK pinout, DG300AAK application, or DG300AAK equivalent, this page delivers verified electrical specs, MIL-STD-883 qualified thermal and switching performance, truth table logic mapping, and direct alternatives for high-reliability analog multiplexing in aerospace, defense, and process control systems.
Technical Context
The DG300AAK implements two independent single-pole single-throw (SPST) switches fabricated on Vishay's PLUS-40 CMOS process with epitaxial isolation to prevent latch-up. Each channel conducts bidirectionally with no offset voltage and supports break-before-make timing only in DG301A_MIL variants-not applicable to DG300AAK.
It operates from dual supplies (±15 V typical), accepts TTL/CMOS-compatible digital inputs (0.8 V low / 4 V high), and blocks up to ±30 V peak-to-peak when off. Its metal-can package provides hermetic sealing and EMI shielding essential for MIL-PRF-38535 Class B applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V - Supports full rail-to-rail analog signals without clipping or distortion across entire supply range. |
| Drain-Source On-Resistance | 30 Ω typ - Minimizes signal attenuation and gain error in precision amplifier and sensor interface paths. |
| Turn-On Time | 150 ns - Enables fast channel selection in time-critical data acquisition and test equipment. |
| Off-Leakage Current | ±100 nA max at hot temperature - Ensures minimal signal corruption in high-impedance sensor front-ends. |
| Supply Voltage Range | V+ = +44 V, V− = −44 V absolute max - Allows robust operation under transient overvoltage conditions per MIL-STD-883. |
| Power Dissipation | 450 mW (10-pin metal can) - Sustains continuous operation at full temperature range with derating above 75 °C. |
| Input Logic Threshold | 0.8 V low / 4 V high - Compatible with standard TTL and CMOS drivers without level-shifting circuitry. |
Pinout & Package
Package: 10-pin metal can (hermetic, side-braze compatible), substrate tied to V+ pin (pin 4), case grounded via mounting flange.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN1 | Digital control input for Channel 1 (active-high). |
| 2 | IN2 | Digital control input for Channel 2 (active-high). |
| 3 | S1 | Source terminal of Channel 1 - bidirectional analog path input/output. |
| 4 | V+ (Substrate and Case) | Positive supply rail and mechanical ground reference; must be connected to system V+. |
| 5 | D2 | Drain terminal of Channel 2 - bidirectional analog path input/output. |
| 6 | D1 | Drain terminal of Channel 1 - bidirectional analog path input/output. |
| 7 | S2 | Source terminal of Channel 2 - bidirectional analog path input/output. |
| 8 | GND | Analog/digital ground reference - isolated from substrate; connects to system ground plane. |
| 9 | V− | Negative supply rail - enables true bipolar analog signal handling down to −15 V. |
| 10 | NC | No connect - internally unconnected; must remain floating or grounded per layout guidelines. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DG300BAAK | P2P replacement per Vishay documentation; same pinout, improved rDS(on) (25 Ω typ), lower leakage (±25 nA), and extended temp range (−55 °C to +125 °C). | Preferred for new designs requiring enhanced analog accuracy and lower power; not qualified to MIL-STD-883 unless specified. | Select DG300BAAK if obsolescence mitigation and tighter specs are prioritized over legacy qualification. |
| JM38510/11601BCA | Same die, 14-pin cerdip package; identical electrical specs but different thermal resistance and mechanical footprint. | Used where board space allows larger package and higher power dissipation (825 mW vs. 450 mW) is needed. | Choose JM38510/11601BCA when upgrading from metal can is impractical and cerdip form factor fits existing layout. |
Compared with DG300AAK, DG300BAAK offers measurable improvements in on-resistance and leakage while maintaining pin compatibility, whereas JM38510/11601BCA trades hermeticity for higher power handling in a ceramic package-both serve distinct reliability and thermal design constraints.

FAQ
What is the operating temperature range for DG300AAK?
The DG300AAK is qualified for operation from −55 °C to +125 °C per MIL-STD-883, with full electrical specifications guaranteed across this range. Its metal-can package ensures thermal stability and hermetic sealing for sustained performance in extreme environmental conditions encountered in aerospace and defense platforms.
Is DG300AAK pin-compatible with DG300BAAK?
Yes, DG300AAK is pin-compatible with DG300BAAK per Vishay's official documentation, which states the DG300B series serves as "pin-for-pin replacements" for the obsolete DG300A_MIL family. Both share identical 10-pin metal-can pinout, substrate connection, and logic interface behavior.
Does DG300AAK support single-supply operation?
No, DG300AAK requires dual supplies (V+ and V−) to achieve its full ±15 V analog signal range and specified on-resistance. Single-supply operation is explicitly supported only by the DG300A_MIL series' non-hermetic variants (e.g., DG300AK), not the MIL-qualified DG300AAK.
What is the maximum analog signal voltage DG300AAK can handle?
DG300AAK guarantees safe operation with analog signals ranging from V− to V+, up to ±15 V under normal conditions. Its absolute maximum ratings allow ±30 V peak-to-peak blocking when off, and V+ and V− rails may be extended to ±44 V per absolute maximum limits-though analog signal swing remains constrained to the applied supply rails.
How does DG300AAK differ from DG301AAK?
DG300AAK contains two independent SPST switches, while DG301AAK implements an SPDT configuration with break-before-make timing. Their pinouts, truth tables, and internal topology differ fundamentally-DG301AAK has dedicated S1/S2/D1/D2 pins for single-pole double-throw operation, whereas DG300AAK uses separate IN/S/D pairs for two isolated SPST channels.
