Product details
Overview
BAS116DY-QX from Nexperia is a low-leakage, medium-speed dual switching diode in SOT363-3 (TSSOP6) package, electrically isolated per diode, rated for 75 V continuous reverse voltage, 5 nA max reverse current at 75 V, and 0.8 µs typical reverse recovery time - deployed in automotive signal routing and precision bias networks.
For engineers reviewing the BAS116DY-QX datasheet, BAS116DY-QX pinout, BAS116DY-QX application, or BAS116DY-QX equivalent, key selection criteria include leakage sensitivity in high-impedance nodes, thermal derating on FR4 PCBs, dual-diode isolation integrity, and AEC-Q101 qualification for under-hood sensor interfaces.
Technical Context
The BAS116DY-QX integrates two independent epitaxial silicon switching diodes in a single 6-pin TSSOP6 package with pins 2 and 5 unconnected - enabling discrete-level isolation without crosstalk. Its 2 pF diode capacitance at 0 V and 0.8 µs trr support clean signal steering in 1–10 MHz analog switch and level-shift circuits.
Rated for 150 °C junction temperature and qualified to AEC-Q101, it sustains stable 5 nA IR up to 150 °C (max 80 nA), making it suitable for automotive cabin temperature sensors and battery monitoring where thermal drift of leakage must remain sub-100 nA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 75 V max - supports 24 V automotive supply rails with 3× safety margin against transients. |
| Reverse Current (IR) | 5 nA max at VR = 75 V, 25 °C - enables use in µA-level bias networks without loading error. |
| Reverse Recovery Time (trr) | 0.8 µs typical - ensures minimal switching distortion in <1 MHz signal path applications. |
| Forward Voltage (VF) | 1.25 V max at IF = 150 mA - limits power loss to <190 mW per diode at rated DC current. |
| Thermal Resistance (Rth(j-a)) | 475 K/W - requires ambient derating above 50 °C when mounted on standard FR4 PCB. |
| Peak Forward Current (IFSM) | 10 A for tp = 50 µs - handles ESD-induced surge pulses without degradation. |
| Package | SOT363-3 (TSSOP6) - 2.2 mm × 1.35 mm footprint compatible with automated SMT assembly. |
Pinout & Package
SOT363-3 (TSSOP6) plastic surface-mount package with 0.65 mm lead pitch, 1.35 mm body width, and exposed pad not present - optimized for reflow soldering on FR4 PCBs with standard stencil-defined paste volume.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A1 | Anode of Diode 1 - connects to input/source side of first switching path. |
| 2 | n.c. | No connection - electrically isolated; must remain unconnected on PCB layout. |
| 3 | K2 | Cathode of Diode 2 - output/sink node for second independent diode path. |
| 4 | A2 | Anode of Diode 2 - independent input for second switching channel. |
| 5 | n.c. | No connection - no internal bond wire; floating terminal must not be tied to ground or signal. |
| 6 | K1 | Cathode of Diode 1 - dedicated return path for first diode, fully isolated from K2. |
Key Features
| Feature | Design Value |
|---|---|
| Low leakage current | 5 nA max at 75 V, 25 °C - preserves accuracy in high-Z sample-and-hold and reference divider networks. |
| Electrically isolated dual diodes | Zero inter-diode capacitance or leakage coupling - enables independent signal routing without crosstalk. |
| AEC-Q101 qualification | Stress-tested for automotive temperature cycling, humidity, and mechanical shock - validated for 15-year vehicle life. |
| Medium-speed switching | 0.8 µs trr with 10 mA/10 mA test conditions - balances speed and low-noise performance in sensor front-ends. |
| Thermal robustness | 150 °C max junction temperature - operates reliably in engine control unit (ECU) proximity without heatsinking. |
Applications
| Automotive Cabin Sensors | High-Voltage Signal Routing |
|---|---|
|
Use Scenario: Voltage-level translation between 5 V microcontroller I/O and 12 V LIN bus transceivers in door modules. IC Role / Device Role / Timing Role: Dual-diode clamping and bidirectional level shifting with independent anode/cathode terminals. Use Value: Prevents latch-up during bus fault events while maintaining <5 nA leakage to avoid false wake-up in sleep mode. |
Use Scenario: Isolating feedback paths in 48 V DC-DC converters used in mild-hybrid powertrain systems. IC Role / Device Role / Timing Role: Reverse-polarity protection and transient suppression on optocoupler input side. Use Value: 75 V VR rating provides 2× margin over 48 V nominal rail; 0.8 µs trr avoids timing skew in PWM feedback loops. |
| Portable Medical Instrumentation | Industrial Analog Multiplexing |
|
Use Scenario: Input protection and signal conditioning in handheld ECG front-end amplifiers with ultra-low input bias current. IC Role / Device Role / Timing Role: Low-leakage clamp diode pair guarding op-amp inputs against ESD and overvoltage. Use Value: 5 nA IR prevents DC offset shift in pA-level transducer signal chains; dual isolation avoids channel crosstalk. |
Use Scenario: Channel-select diode matrix in 16-channel industrial data acquisition systems with multiplexed thermocouple inputs. IC Role / Device Role / Timing Role: Passive analog switch element enabling sequential channel connection to shared ADC front-end. Use Value: 2 pF Cd minimizes settling time; independent cathodes allow grounded-sensor configurations without common-mode interference. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-leakage diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSR20F40NXT5G | Higher VF (1.35 V @ 150 mA); lower IR (1 nA @ 75 V); same SOT-363 package. | Preferred in ultra-low-power battery monitors where leakage dominates budget but forward drop is secondary. | Select when IR < 2 nA is mandatory and 0.1 V higher VF is acceptable in DC bias paths. |
| Vishay SMBD7000-GS08 | Higher VR (100 V); slower trr (3 µs typ); larger SOT-363-2 footprint (2.2 mm × 1.35 mm same, but different pin 2/5 definition). | Suitable for 48 V industrial PLC I/O protection where speed is less critical than voltage margin. | Choose for 100 V transient immunity needs; verify pin compatibility - pin 2 is K1 (not n.c.) in SMBD7000. |
Compared with NSR20F40NXT5G and SMBD7000-GS08, the BAS116DY-QX delivers optimal balance of leakage (5 nA), speed (0.8 µs), and AEC-Q101 compliance - making it the preferred choice for automotive sensor signal conditioning where all three parameters are simultaneously constrained.

FAQ
Is BAS116DY-QX pin-compatible with BAS116 series predecessors?
Yes - BAS116DY-QX maintains identical SOT363-3 pinout and electrical specifications as prior BAS116DY variants, including pin 2 and pin 5 as no-connect terminals. The '-Q' suffix denotes AEC-Q101 qualification; no layout changes are required for migration from non-Q versions.
Can BAS116DY-QX be used in parallel for higher current handling?
No - the device contains two electrically isolated diodes, but they share a common thermal path in the SOT363-3 package. Parallel operation of A1/K1 and A2/K2 is not recommended due to mismatched VF and thermal runaway risk; maximum per-diode IF remains 200 mA continuous.
What is the maximum allowable PCB copper area for thermal relief?
Per Nexperia's thermal characterization, the 475 K/W Rth(j-a) assumes a standard FR4 board with single-sided 1 oz copper, tin-plated, and footprint matching Figure 8. Increasing copper area beyond the defined 2.65 mm × 2.35 mm solder land does not significantly improve thermal resistance due to package-limited conduction.
Does BAS116DY-QX support wave soldering?
Yes - Nexperia provides a dedicated wave soldering footprint (Figure 9) with 5.3 mm length and 1.3 mm width lands. Peak temperature must not exceed 260 °C for ≤10 s, and flux residue must be removed to prevent long-term leakage degradation in humid environments.
