Product details
Overview
BAS16J-Q from Nexperia is a high-speed switching diode in SOD323F (SC-90) package, rated for 100 V repetitive peak reverse voltage, 4 ns reverse recovery time, and 250 mA forward current. It serves as a fast-turn-off signal path switch in automotive power management and ECU input conditioning circuits.
For engineers reviewing the BAS16J-Q datasheet, BAS16J-Q pinout, BAS16J-Q application, or BAS16J-Q equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance values, and automotive-grade reliability context - all critical for signal integrity validation and board-level timing margin analysis.
Technical Context
The BAS16J-Q employs a planar epitaxial silicon structure optimized for low charge storage and minimal minority carrier lifetime, enabling sub-4 ns trr under IF = IR = 10 mA test conditions. Its junction capacitance remains ≤1.5 pF at 0 V bias, supporting RF-coupled logic interface and clamping functions up to ~500 MHz.
Thermal design is constrained by Rth(j-a) = 230 K/W on FR4 PCB with single-sided copper, and Rth(j-sp) = 55 K/W to cathode solder point - making it suitable for thermally isolated routing in compact automotive modules where ambient temperatures reach 125 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - supports 24 V automotive systems with ≥4× safety margin against load-dump transients |
| trr | 4 ns - enables clean edge transition in 100+ MHz digital signal routing and pulse shaping |
| VF @ 10 mA | 855 mV - ensures low forward drop in low-voltage logic-level clamping without excessive self-heating |
| IR @ 80 V | 0.5 µA at 25 °C - minimizes leakage-induced offset error in precision sensor front-ends |
| Cd @ 0 V | 1.5 pF - preserves signal rise/fall times in high-speed data lines (e.g., CAN FD stubs, LIN bus protection) |
| Ptot | 550 mW - allows continuous operation at 250 mA forward current only with adequate PCB copper area |
| Tj max | 150 °C - qualified for under-hood applications including engine control and transmission modules |
Pinout & Package
Package: SOD323F (SC-90), surface-mounted plastic package measuring 1.7 mm × 1.25 mm × 0.7 mm with gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K (cathode) | Connected to higher-potential node during reverse bias; primary thermal path to PCB via cathode pad |
| 2 | A (anode) | Connected to lower-potential node during conduction; carries full forward current with minimal parasitic inductance |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use per stress test requirements - eliminates need for customer requalification |
| trr ≤ 4 ns | Enables reliable switching in >100 MHz clock distribution networks and high-frequency PWM gate drive snubbers |
| Low IR (0.5 µA @ 80 V) | Reduces standby current loss in always-on vehicle subsystems such as telematics wake-up circuits |
| SOD323F footprint | Compatible with standard 0201-class pick-and-place equipment and reflow profiles - no process change required |
| Rth(j-sp) = 55 K/W | Supports localized thermal relief design using dedicated cathode thermal pad without internal vias |
Applications
| Automotive ECU Input Protection | High-Speed Logic-Level Clamping |
|---|---|
Use Scenario: Protecting microcontroller GPIO pins from inductive kickback and battery transients in body control modules. IC Role / Device Role / Timing Role: Fast-recovery clamp diode placed between I/O line and supply rail to shunt transient energy within 4 ns. Use Value: Prevents latch-up and permanent damage while maintaining <100 ps timing skew on 10 MHz CAN/LIN signals. |
Use Scenario: Level-shifting and overvoltage clamping in mixed-voltage FPGA I/O banks interfacing with 3.3 V/1.8 V peripherals. IC Role / Device Role / Timing Role: Signal-path diode providing bidirectional clamping to VCC and GND rails with minimal capacitive loading. Use Value: Limits overshoot to <0.8 V above VCC without distorting 200 Mbps LVDS eye diagrams due to 1.5 pF Cd. |
| USB 2.0 Data Line ESD Suppression | DC-DC Converter Snubber Network |
Use Scenario: Secondary ESD protection stage downstream of TVS diodes on USB D+/D− lines in infotainment head units. IC Role / Device Role / Timing Role: Low-capacitance switching diode absorbing residual 100–200 ps ESD pulses after primary TVS clamping. Use Value: Adds <0.5 pF parasitic capacitance to maintain USB 2.0 eye compliance while reducing post-ESD leakage to <1 nA. |
Use Scenario: RC snubber across MOSFET drain-source in 48 V–12 V buck converters for ADAS camera power supplies. IC Role / Device Role / Timing Role: Fast-recovery diode diverting turn-off spike energy into snubber capacitor before voltage overshoot exceeds 100 V rating. Use Value: Enables 500 kHz switching with <5% efficiency penalty and eliminates need for active clamp circuitry. |
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 MMBD1201LT1G | trr = 3.5 ns, VR = 100 V, VF = 1.25 V @ 150 mA - higher forward drop increases conduction loss | Preferred in cost-sensitive industrial SMPS where thermal margin exceeds 20 °C | Select when lower trr outweighs VF penalty and AEC-Q101 is not required |
| Diodes Incorporated BAV199LT1G | trr = 5 ns, VR = 80 V, dual-diode configuration in SOT-23 - reduced voltage margin and larger footprint | Used in dual-rail level translators requiring matched pair characteristics | Choose only when dual-diode topology and 80 V rating suffice for system-level transient protection |
Compared with MMBD1201LT1G and BAV199LT1G, the BAS16J-Q uniquely balances AEC-Q101 compliance, 4 ns trr, and 1.7 mm² footprint - making it optimal for space-constrained automotive modules needing guaranteed reliability without sacrificing speed.

FAQ
Is BAS16J-Q suitable for 12 V automotive battery line protection?
No - while rated for 100 V VRRM, its 250 mA IF rating and 550 mW Ptot limit continuous current handling. It is intended for signal-level switching and clamping, not main power line protection. For battery line protection, use dedicated TVS or load-switch ICs with higher surge ratings.
What is the maximum allowable PCB temperature rise when operating at 200 mA DC?
At 200 mA DC and Tamb = 85 °C, junction temperature reaches ~125 °C assuming Rth(j-a) = 230 K/W. To stay below Tj(max) = 150 °C, PCB temperature rise must remain ≤25 K - achievable with ≥1 cm² cathode copper pour and no adjacent heat sources.
Does BAS16J-Q support reflow soldering per JEDEC J-STD-020?
Yes - the SOD323F package is qualified for standard lead-free reflow profiles (peak 260 °C, 20–40 s above 217 °C). The datasheet provides exact footprint dimensions (Fig. 8) and recommends 0.5 mm × 0.6 mm solder pads with 0.6 mm spacing for optimal wetting and coplanarity.
How does BAS16J-Q differ from generic BAS16 variants?
The "-Q" suffix denotes AEC-Q101 qualification, extended temperature range (−65 °C to +150 °C), enhanced wafer-level screening, and automotive-specific traceability. Generic BAS16 parts lack these qualifications and are not approved for automotive use per ISO/TS 16949 requirements.
