Product details
Overview
BAS16J/ZLX from Nexperia is a high-speed switching diode in SOD323F (SC-90) surface-mount package, configured as a single discrete silicon junction diode with cathode-anode polarity. It delivers trr ≤ 4 ns reverse recovery time, VR = 100 V maximum reverse voltage, IF = 250 mA forward current rating, and Cd = 1.5 pF capacitance at 1 MHz - enabling use in fast-switching DC-DC converter flyback snubbers and ESD-protected signal line clamping.
For engineers reviewing the BAS16J/ZLX datasheet, BAS16J/ZLX pinout, BAS16J/ZLX application, or BAS16J/ZLX equivalent, key selection criteria include verified 4 ns trr performance under IF = 10 mA / IR = 10 mA test conditions, AEC-Q101 qualification for automotive environments, low-leakage operation (IR ≤ 0.5 µA at VR = 80 V), and thermal resistance Rth(j-sp) = 55 K/W to solder point.
Technical Context
This diode employs a planar epitaxial silicon structure optimized for rapid carrier recombination, achieving sub-4 ns reverse recovery via controlled minority-carrier lifetime reduction. Its low-junction-capacitance design (1.5 pF at 0 V) minimizes signal distortion in RF detector and high-frequency clamp circuits.
The device operates within −65 °C to +150 °C ambient range, with junction temperature limited to 150 °C. Thermal resistance from junction to solder point is 55 K/W, indicating efficient heat transfer through the cathode pad - critical for sustained 250 mA forward conduction in compact PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Recovery Time (trr) | 4 ns max at IF = 10 mA, IR = 10 mA - enables >100 MHz switching in snubber and sampling circuits |
| Repetitive Peak Reverse Voltage (VRRM) | 100 V - supports 48 V industrial bus protection and 24 V automotive power rail clamping |
| Forward Current (IF) | 250 mA continuous - sufficient for logic-level signal steering and low-power rectification |
| Junction-to-Solder Point Thermal Resistance (Rth(j-sp)) | 55 K/W - allows direct thermal coupling to copper pour for stable operation at full rated current |
| Diode Capacitance (Cd) | 1.5 pF at f = 1 MHz, VR = 0 V - preserves signal integrity in 50 Ω RF paths and high-speed data lines |
| Reverse Leakage Current (IR) | 0.5 µA max at VR = 80 V, 25 °C - ensures minimal standby power loss in always-on protection circuits |
| Forward Voltage (VF) | 855 mV typ at IF = 10 mA - balances low conduction loss with fast switching capability |
Pinout & Package
SOD323F (SC-90) is a 2-terminal ultra-small flat-lead plastic SMD package measuring 1.35 × 0.85 × 0.45 mm, with cathode marked by a band on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to PCB ground or negative rail; marking bar identifies this terminal |
| 2 | Anode | Input node for forward conduction; routed to signal source or positive supply |
Key Features
| Feature | Design Value |

| Ultra-fast switching | trr ≤ 4 ns enables clean edge transitions in pulse-width modulated control feedback paths |
| Low leakage current | IR ≤ 0.5 µA at 80 V supports battery-backed real-time clock backup and low-power sensor interfaces |
| Small footprint | SOD323F package occupies only 1.15 mm² board area - ideal for space-constrained portable electronics |
| Thermal efficiency | Rth(j-sp) = 55 K/W permits 250 mA operation without external heatsinking on standard FR4 |
Applications
| Automotive CAN Bus Protection | USB 2.0 Data Line Clamping |
|---|---|
|
Use Scenario: Bidirectional transient suppression on CAN_H/CAN_L lines in body control modules. IC Role / Device Role / Timing Role: Discrete clamping diode placed between data line and ground, conducting during ESD events. Use Value: 4 ns trr prevents signal edge degradation during 1 Mbps CAN communication; 100 V VRRM withstands load-dump transients. |

IC Role / Device Role / Timing Role: Forward-biased anode-cathode path establishing voltage offset. Use Value: 855 mV VF at 10 mA provides predictable 3.3 V → 5 V translation margin; SOD323F enables dense routing. |
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 |
|---|---|---|---|
| BAS316 | Same SOD323 package but SC-76 outline; Cd = 1.5 pF, trr = 4 ns, IF = 250 mA - identical electrical specs, minor mechanical footprint variance | Compatible with same PCB land pattern per Nexperia footprint doc sod323_fr; no layout change required | Select when sourcing flexibility is needed; identical performance and qualification status |
| BAS516 | SOD523 (SC-79) package: smaller (1.25 × 0.85 × 0.45 mm), lower Cd = 1.0 pF, same trr = 4 ns and VRRM = 100 V | Better suited for <1 GHz RF signal paths due to reduced parasitic capacitance; requires revised stencil aperture | Choose for ultra-high-frequency applications where 0.5 pF capacitance reduction justifies requalification |
Compared with BAS16J/ZLX, BAS316 offers drop-in mechanical compatibility with identical electrical behavior, while BAS516 trades slightly reduced current rating (200 mA vs. 250 mA) for lower capacitance in tighter RF layouts - making BAS16J/ZLX optimal for general-purpose high-speed switching where thermal margin and layout reuse are prioritized.

FAQ
What is the maximum operating temperature for BAS16J/ZLX?
The BAS16J/ZLX has a maximum junction temperature (Tj) of 150 °C and an ambient operating range of −65 °C to +150 °C. Its thermal resistance from junction to solder point is 55 K/W, allowing reliable operation at full 250 mA forward current on standard FR4 PCBs with adequate copper area.
Is BAS16J/ZLX suitable for automotive applications?
Yes - BAS16J/ZLX is AEC-Q101 qualified per the Nexperia product data sheet Rev. 6 (2014), having passed stress tests including temperature cycling, high-temperature reverse bias, and ESD (HBM ≥ 8 kV). It is approved for use in automotive body electronics, infotainment, and powertrain subsystems.
How does the SOD323F package differ from SOD323?
SOD323F (SC-90) is a flat-lead variant of SOD323 with shorter leads and reduced height (0.45 mm vs. 0.65 mm), designed for improved coplanarity and reflow yield. The pinout remains cathode-anode (pin 1 = cathode), and Nexperia specifies identical electrical characteristics and solder footprints (sod323f_fr).
What is the reverse recovery test condition for the 4 ns specification?
The 4 ns trr value is measured under standardized conditions: IF = 10 mA forward current, IR = 10 mA reverse current, RL = 100 Ω load resistance, and IR(meas) = 1 mA threshold - per IEC 60747-2 and documented in Table 2 of the BAS16_SER Rev. 6 datasheet.
