Product details
Overview
BAS16J-QX from Nexperia is a high-speed switching diode in SOD323F (SC-90) package, rated for 100 V reverse voltage, 4 ns reverse recovery time, and 250 mA forward current. It serves as a fast-switching signal path component in automotive power management and communication interface circuits where low capacitance (1.5 pF) and low leakage (0.5 µA at 80 V) are critical.
For engineers reviewing the BAS16J-QX datasheet, BAS16J-QX pinout, BAS16J-QX application, or BAS16J-QX equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance values (Rth(j-a) = 230 K/W), and real-world use context for automotive-grade discrete selection.
Technical Context
This diode operates as a unidirectional, single-junction silicon switching element with cathode-anode polarity defined per SC-90 pinning. Its 4 ns trr enables reliable operation in 100+ MHz digital signal routing and flyback snubbing up to 1 MHz switching frequencies.
Thermal design relies on its 55 K/W junction-to-solder-point resistance and 150 °C maximum junction temperature. The device is characterized under pulsed conditions (δ ≤ 0.02, tp ≤ 300 µs), with VF specified at 1.25 V @ 150 mA and Cd measured at 1.5 pF @ 0 V, 1 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 100 V - supports 24 V and 48 V automotive bus protection without derating. |
| Reverse Recovery Time (trr) | 4 ns - enables clean edge transitions in high-frequency logic-level translation and clamping. |
| Forward Voltage (VF) | 1.25 V @ 150 mA - minimizes conduction loss in low-duty-cycle pulse applications. |
| Diode Capacitance (Cd) | 1.5 pF @ 0 V, 1 MHz - preserves signal integrity in RF-coupled and high-speed data lines. |
| Reverse Leakage (IR) | 0.5 µA @ 80 V, 25 °C - ensures stable biasing in precision sensor front-ends and reference dividers. |
| Thermal Resistance (Rth(j-a)) | 230 K/W - defines minimum PCB copper area needed for ambient-limited thermal management. |
Pinout & Package
Package: SOD323F (SC-90), surface-mounted plastic package measuring 1.7 mm × 1.25 mm × 0.7 mm, qualified per AEC-Q101 for automotive use.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to higher-potential node during reverse bias; primary heat path to PCB via cathode pad. |
| 2 | Anode (A) | Current entry point during forward conduction; referenced to ground or low-side return paths. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive underhood environments (−40 °C to +150 °C) with zero defect screening. |
| Low trr (≤ 4 ns) | Reduces switching losses and prevents shoot-through in synchronous rectifier and level-shift circuits. |
| Small SOD323F footprint | Enables dense layout in space-constrained ADAS modules and infotainment power rails. |
| Low Cd (1.5 pF) | Maintains >1 GHz bandwidth in ESD protection networks and high-speed GPIO clamping. |
Applications
| Automotive Body Control Module | USB 2.0 Data Line Protection |
|---|---|
Use Scenario: Clamping transient spikes on LIN bus lines during load dump events. IC Role / Device Role / Timing Role: Fast-recovery diode in parallel TVS-assisted protection network. Use Value: 4 ns trr ensures minimal delay between surge onset and clamping activation, preserving signal fidelity. |
Use Scenario: ESD suppression on D+/D− lines before USB transceiver input. IC Role / Device Role / Timing Role: Low-capacitance steering diode in I/O protection array. Use Value: 1.5 pF Cd avoids signal rise-time degradation beyond USB 2.0 specification (≤ 1.5 ns). |
| DC-DC Converter Snubber | Industrial Sensor Signal Conditioning |
Use Scenario: Absorbing leakage inductance energy in flyback transformer secondary. IC Role / Device Role / Timing Role: High-speed freewheeling path during MOSFET turn-off. Use Value: 100 V VR rating accommodates reflected voltage spikes up to 85 V in 24 V input designs. |
Use Scenario: Precision voltage clamping in thermistor-based temperature measurement bridges. IC Role / Device Role / Timing Role: Reverse-biased reference limiter for analog front-end inputs. Use Value: 0.5 µA IR at 80 V prevents measurable offset drift in µA-level bridge currents. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSVRBAS16WT1G | Same SOD-323 package, 4 ns trr, but lower VR (70 V) and higher IR (1 µA @ 50 V). | Suitable only for ≤ 24 V systems; not recommended for 48 V automotive power domains. | Select when cost sensitivity outweighs 100 V margin and AEC-Q101 traceability is non-mandatory. |
| Vishay BAV199,215 | SC-70 package, 4 ns trr, 100 V VR, but higher Cd (2.5 pF) and no AEC-Q101 certification. | Acceptable for industrial control, but excluded from automotive safety-critical subsystems. | Choose only for legacy board redesigns where SC-70 footprint compatibility is required. |
Compared with NSVRBAS16WT1G and BAV199,215, BAS16J-QX uniquely combines AEC-Q101 qualification, 100 V rating, 1.5 pF capacitance, and SOD323F footprint-making it the sole option for new automotive designs requiring full compliance and minimal parasitic loading.

FAQ
Is BAS16J-QX pin-compatible with BAS16,115?
No. BAS16J-QX uses the SOD323F (SC-90) package with 1.7 mm × 1.25 mm footprint and cathode-anode pinout (Pin 1 = K, Pin 2 = A). BAS16,115 is in SOT23 package with different pin assignment and larger dimensions (2.9 mm × 1.3 mm), making them mechanically and layout-incompatible.
What is the maximum continuous forward current for BAS16J-QX at 85 °C ambient?
The maximum continuous forward current is derated from 250 mA at 25 °C to approximately 180 mA at 85 °C ambient, based on its 550 mW total power dissipation limit and Rth(j-a) of 230 K/W. This assumes standard FR4 PCB mounting with 1 cm² cathode pad copper area.
Does BAS16J-QX require special reflow profile considerations?
Yes. Per Nexperia's SOD323F footprint guidelines, peak reflow temperature must not exceed 260 °C for ≤ 10 seconds, with ramp-up rate ≤ 3 °C/s. The recommended solder land pattern (0.6 mm × 0.5 mm pads, 0.8 mm center-to-center) ensures reliable wetting without tombstoning.
Can BAS16J-QX be used in bidirectional ESD protection configurations?
No. BAS16J-QX is a unidirectional diode. For bidirectional ESD protection, two devices must be connected anode-to-anode or cathode-to-cathode in series. Its 100 V VR rating applies only in reverse bias; forward conduction occurs above ~0.7 V, limiting clamping symmetry.
