Product details
Overview
BAS16GW from Nexperia is a high-speed switching diode in SOD123 package, designed for fast voltage transitions in signal routing and power control paths. It delivers trr ≤ 4 ns reverse recovery time, VR = 100 V maximum reverse voltage, and Cd ≤ 1.5 pF junction capacitance - enabling reliable operation in 50 MHz+ digital logic interfaces and DC-DC converter snubbers.
For engineers reviewing the BAS16GW datasheet, BAS16GW pinout, BAS16GW application, or BAS16GW equivalent, key selection criteria include verified AEC-Q101 qualification, thermal resistance Rth(j-a) = 350 K/W on FR4, and cathode/anode polarity validation per SOD123 mechanical outline.
Technical Context
The BAS16GW operates as a unidirectional silicon switching diode with low forward voltage drop (VF = 855 mV at IF = 10 mA) and tightly controlled reverse leakage (IR = 0.5 µA at VR = 80 V). Its 4 ns trr is measured under standardized conditions: IF = IR = 10 mA, RL = 100 Ω, IR(meas) = 1 mA.
Thermal performance is defined for two mounting configurations: Rth(j-a) = 350 K/W on standard FR4 footprint and Rth(j-sp) = 58 K/W to cathode solder point. Junction temperature is rated to 150 °C, supporting automotive under-hood and industrial ambient environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 100 V - supports input stage clamping in 48 V industrial bus systems and flyback snubber circuits. |
| Reverse Recovery Time (trr) | ≤ 4 ns - enables clean switching in >50 MHz clock distribution and high-frequency PWM gate drivers. |
| Junction Capacitance (Cd) | ≤ 1.5 pF at 1 MHz, VR = 0 V - minimizes signal distortion in RF detector and high-speed data line protection. |
| Forward Voltage (VF) | 855 mV at IF = 10 mA - reduces conduction loss in low-voltage logic-level translation and level-shifting networks. |
| Reverse Leakage (IR) | 0.5 µA at VR = 80 V, Tj = 25 °C - ensures stable biasing in precision analog sample-and-hold and reference divider chains. |
| Thermal Resistance (Rth(j-a)) | 350 K/W on FR4 PCB - defines maximum power dissipation (357 mW) without heatsink in compact SMT layouts. |
Pinout & Package
SOD123 surface-mount plastic package: 2.80 mm × 1.70 mm body, 0.91 mm height, cathode marked with band and "GA" laser marking. Cathode terminal occupies larger copper pad per IPC-7351B standard footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to higher-potential node during reverse bias; primary thermal path to PCB via 1 cm² cathode pad. |
| 2 | Anode (A) | Connected to lower-potential node during conduction; carries full forward current up to 215 mA DC. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive powertrain and body electronics per stress test requirements including HTGB, TC, and HTRB. |
| Low trr ≤ 4 ns | Enables use in 100+ kHz synchronous rectifier control loops without shoot-through risk. |
| Small SOD123 footprint | Reduces board area by 40% vs. DO-35, supporting dense layout in USB-C PD controllers and PMICs. |
| Low Cd ≤ 1.5 pF | Maintains signal integrity in 100 Mbps LVDS and MIPI D-PHY receiver protection circuits. |
Applications
| Automotive Door Module | Industrial PLC Input Protection |

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 MMBD1203 | trr = 3.5 ns (typ), VR = 70 V, SOD-323 package (smaller, 1.7 × 1.25 mm) | Limited to 70 V systems; unsuitable for 48 V industrial bus clamping | Select when board space is constrained and reverse voltage ≤ 70 V. |
| Vishay 1N4148WS | trr = 4 ns (max), VR = 100 V, same SOD-123 footprint but not AEC-Q101 qualified | Not validated for automotive temperature cycling or humidity testing | Select for cost-sensitive consumer applications where AEC-Q101 is not required. |
Compared with MMBD1203 and 1N4148WS, the BAS16GW uniquely combines AEC-Q101 qualification, 100 V VR rating, and SOD123 manufacturability - making it the only option qualified for under-hood automotive switching and industrial 48 V rail protection.

FAQ
Is BAS16GW suitable for 100 kHz PWM motor control freewheeling?
Yes. With trr ≤ 4 ns and IF = 215 mA DC rating, the BAS16GW safely commutates inductive loads at 100 kHz without reverse recovery losses dominating efficiency. Its 100 V VR rating covers back-EMF spikes in 24 V brushed DC motor drives, and thermal resistance of 350 K/W allows direct PCB heat sinking without additional thermal vias.
What is the meaning of 'GA' marking on BAS16GW?
The 'GA' laser marking on the cathode side of the SOD123 package is the official Nexperia device code for BAS16GW, per Table 4 of the datasheet. It distinguishes this variant from other BAS16-series diodes (e.g., BAS16, BAS16H) and confirms compliance with AEC-Q101 stress test requirements.
Can BAS16GW replace 1N4148 in existing designs?
Yes, with verification. BAS16GW matches 1N4148's 100 V VR and 4 ns trr ratings but uses SOD123 instead of DO-35. The SOD123 footprint requires PCB land pattern update, and its 350 K/W Rth(j-a) is 15% higher than DO-35's typical 300 K/W - verify thermal margin at full load in your layout.
Does BAS16GW support wave soldering?
Yes. Nexperia provides dedicated wave soldering footprint data (Fig. 11) with 2.55 mm × 2.4 mm solder land and 7.5 mm × 4.5 mm occupied area. Peak temperature must stay below 260 °C for ≤ 10 seconds, and preheat ramp rate should not exceed 3 °C/s to avoid delamination per SOD123 mechanical specification.
