Product details
Overview
BAS416-QX from Nexperia is a low-leakage, medium-speed switching diode in SOD323 package, featuring 3 pA typical reverse leakage at 75 V, 0.8 µs typical reverse recovery time, and AEC-Q101 qualification for automotive use. It serves as a precision signal path switch or clamping element in high-impedance analog front-ends and sensor interfaces.
For engineers reviewing the BAS416-QX datasheet, BAS416-QX pinout, BAS416-QX application, or BAS416-QX equivalent, key selection criteria include ultra-low IR (≤5 nA max), fast trr (≤3 µs), 85 V VRRM rating, and SOD323 footprint compatibility with space-constrained PCB layouts in automotive and industrial sensing systems.
Technical Context
The BAS416-QX employs an epitaxial silicon structure optimized for low junction capacitance (2 pF at 0 V) and minimal charge storage, enabling clean switching in sample-and-hold circuits and precision voltage clamping. Its thermal resistance (Rth(j-a) = 450 K/W on FR4) supports operation up to 150 °C junction temperature.
Designed for pulsed and continuous forward conduction up to 200 mA, it maintains stable VF (1.1 V at 50 mA) across −55 °C to +150 °C ambient range. Reverse recovery is characterized under standardized IFRM = 500 mA and VR = 75 V conditions per IEC 60134 limiting values.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 85 V - supports reverse blocking in 24 V and 48 V automotive power domains with 10 V safety margin |
| IR @ 75 V | 3 pA typ., 5 nA max - enables nanoamp-level bias stability in photodiode amplifiers and leakage-sensitive comparators |
| trr | 0.8 µs typ., 3 µs max - ensures minimal switching distortion in <1 MHz signal routing and multiplexing applications |
| VF @ 50 mA | 1.1 V - delivers predictable forward drop for accurate current-source referencing and level-shifting |
| Cd @ 0 V | 2 pF - minimizes capacitive loading on high-frequency sensor outputs and RF detector nodes |
| Ptot | 250 mW - defines maximum dissipation on standard FR4 PCB without heatsinking or forced airflow |
Pinout & Package
SOD323 surface-mount plastic package: 1.7 mm × 1.25 mm × 0.95 mm body, 1.3 mm lead pitch, tin-plated copper leads compatible with reflow and wave soldering per JEDEC J-STD-020/003.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K (cathode) | Connected to higher-potential node during forward conduction; polarity marker for unidirectional current flow |
| 2 | A (anode) | Connected to lower-potential node during forward conduction; primary terminal for bias injection and signal routing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-leakage switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSVRBAS416WT1G | Same SOD323 package; 5 nA max IR at 75 V (vs. 5 nA for BAS416-QX); trr = 1.2 µs typ. | Higher trr limits use in >500 kHz sampling; identical AEC-Q101 qualification supports direct automotive substitution. | Select when legacy ON Semi BOM alignment is required and 1.2 µs trr meets system timing budget. |
| Vishay VS-2EDH02HM3/85A | SOD-523 package (1.2 × 0.8 mm); 10 nA max IR; VF = 1.25 V at 50 mA; no AEC-Q101 certification. | Smaller footprint trades off leakage performance and automotive compliance; suited for consumer wearables only. | Choose only for space-constrained non-automotive designs where 10 nA IR and absence of automotive qualification are acceptable. |
Compared with NSVRBAS416WT1G and VS-2EDH02HM3/85A, the BAS416-QX delivers the lowest confirmed leakage (3 pA typ.), fastest trr (0.8 µs typ.), and full AEC-Q101 validation-making it the sole option for high-precision, thermally demanding automotive sensor nodes requiring sub-nA bias integrity.

FAQ
What is the maximum continuous forward current for BAS416-QX at 100 °C ambient?
At 100 °C ambient temperature on a standard FR4 PCB, the maximum permissible continuous forward current is 120 mA, derived from the derating curve in Figure 1 of the datasheet. This value accounts for thermal resistance (450 K/W) and junction temperature limit (150 °C), ensuring safe operation without exceeding Ptot = 250 mW.
Does BAS416-QX support wave soldering, and what are the recommended footprint dimensions?
Yes, BAS416-QX is qualified for wave soldering. The recommended footprint uses 0.6 mm wide solder lands with 1.2 mm spacing (center-to-center), 2.75 mm overall length, and 1.5 mm transport direction alignment per Figure 9 of the datasheet. Solder resist openings match land dimensions to prevent bridging.
How does the 3 pA typical leakage compare to industry benchmarks for SOD323 diodes?
At 75 V reverse bias and 25 °C, BAS416-QX's 3 pA typical IR is among the lowest published for commercial SOD323 diodes-approximately 3× lower than standard BAS16 variants (10–15 pA) and 10× lower than typical Schottky diodes in same package, enabling new levels of DC accuracy in high-Z analog paths.
Is the marking code 'D4' unique to BAS416-QX, and how is it verified on the device?
Yes, 'D4' is the exclusive top-side laser marking for BAS416-QX per Table 4 of the datasheet. It appears as a two-character alphanumeric code on the cathode side of the SOD323 body, aligned with Pin 1 (K), and is verified under 20× magnification using optical inspection per Nexperia's traceability protocol.
