Product details
Overview
BAS116GWX from Nexperia is a low-leakage switching diode in SOD123 package, designed for precision signal routing and voltage clamping where ultra-low reverse current (3 pA typ. at 75 V, 25 °C) and fast recovery (0.8 µs typ.) are critical. It supports repetitive peak reverse voltage up to 85 V, forward current to 215 mA, and operates across −55 °C to +150 °C junction temperature - used in automotive sensor biasing and high-impedance analog front-ends.
For engineers reviewing the BAS116GWX datasheet, BAS116GWX pinout, BAS116GWX application, or BAS116GWX equivalent, key selection criteria include verified leakage performance at elevated temperature, AEC-Q101 qualification status, SOD123 thermal resistance (210 K/W junction-to-solder point), and compatibility with reflow/wave soldering footprints per IPC-7351.
Technical Context
This discrete silicon switching diode uses planar epitaxial construction to achieve sub-nA reverse leakage and controlled minority-carrier lifetime for predictable trr behavior. Its 2 pF capacitance at 0 V and 1 MHz enables minimal signal distortion in RF sampling and high-frequency detector circuits.
The device is fully characterized per IEC 60134 absolute maximum ratings, with thermal design validated on FR4 PCBs using standard and enhanced cathode-pad footprints. Junction-to-ambient Rth(j-a) is 350 K/W (standard) and 210 K/W (enhanced pad), directly supporting power derating in compact automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 85 V - Maximum repetitive reverse blocking voltage without breakdown; defines safe operating range in clamp/protection circuits. |
| IR @ VR = 75 V, 25 °C | 3 pA typ. - Enables stable DC bias in >1 GΩ impedance nodes (e.g., photodiode transimpedance amplifiers). |
| trr | 0.8 µs typ. - Supports switching frequencies up to ~500 kHz with minimal tail current in flyback snubbers and sample-hold paths. |
| Cd @ VR = 0 V, 1 MHz | 2 pF - Limits capacitive loading on high-speed logic inputs and preserves bandwidth in RF detector outputs. |
| VF @ IF = 150 mA | 1.25 V max - Ensures low conduction loss in low-duty-cycle pulse applications such as LED strobing and gate drive isolation. |
| Ptot | 600 mW - Specifies maximum steady-state dissipation on FR4 with 1 cm² cathode pad; requires thermal layout verification. |
| AEC-Q101 qualified | Qualified for automotive use - meets stress test requirements for temperature cycling, HTRB, and ESD (HBM ≥ 8 kV). |
Pinout & Package
Encapsulated in SOD123 surface-mount plastic package (3.75 × 2.55 × 1.3 mm), with standardized cathode marking (GB) and defined solder land geometry per IPC-7351.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to higher-potential node during reverse bias; carries full forward current; primary thermal path to PCB via cathode pad. |
| 2 (A) | Anode | Connected to lower-potential node during conduction; electrically isolated from thermal pad; defines polarity in series-switching configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Low leakage current | 3 pA typical at 75 V, 25 °C - maintains accuracy in high-impedance feedback networks and sensor biasing without drift. |
| Fast reverse recovery | 0.8 µs typical - reduces switching losses and prevents shoot-through in synchronous rectifier and charge-pump topologies. |
| Small SMD footprint | SOD123 outline (3.75 × 2.55 mm) - enables dense placement in space-constrained automotive ECUs and portable instrumentation. |
| AEC-Q101 qualification | Validated for automotive grade-1 (−40 °C to +125 °C ambient) operation - ensures reliability in engine control, ADAS, and body electronics. |
| Low diode capacitance | 2 pF at 0 V - minimizes signal coupling and phase shift in RF detector and high-speed comparator input protection. |

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 NSS1C200LT1G | Higher IR (5 nA typ. @ 75 V) and slower trr (3.5 µs typ.), same SOD-123 package. | Acceptable in non-precision biasing but unsuitable for >14-bit measurement front-ends. | Select when cost sensitivity outweighs leakage-critical performance; verify thermal margin at 150 °C. |
| Vishay ES1J | Higher VRRM (600 V) but significantly higher IR (100 nA) and Cd (30 pF); DO-214AC package. | Used in AC line rectification, not low-leakage analog signal paths. | Only consider for high-voltage, non-precision switching; incompatible footprint and leakage spec. |
Compared with NSS1C200LT1G and ES1J, BAS116GWX uniquely balances ultra-low leakage (3 pA), fast recovery (0.8 µs), and SOD123 size - making it the only option qualified for AEC-Q101 and specified for high-resolution sensor interfaces requiring sub-pA stability.

FAQ
What is the maximum junction temperature rating for BAS116GWX?
The absolute maximum junction temperature is 150 °C, validated per IEC 60134. Operation at this limit requires thermal design with the enhanced cathode pad footprint (Rth(j-sp) = 210 K/W) and derating of Ptot to ≤357 mW on standard FR4. Continuous operation above 125 °C requires validation of leakage drift per Figure 4.
Is BAS116GWX suitable for bidirectional ESD protection?
No - BAS116GWX is a unidirectional switching diode with anode-cathode polarity. It provides reverse-bias clamping only. For bidirectional ESD protection, dedicated TVS diodes like PESD5V0S1BA (SOD-323) or dual-rail arrays must be used instead.
How does the 3 pA leakage specification scale at elevated temperature?
Per Figure 4, typical IR increases to 3 nA at 150 °C and 75 V. This 1000× increase is inherent to silicon physics and must be accounted for in high-temperature bias networks - e.g., a 10 MΩ feedback resistor will develop 30 mV offset at 150 °C.
Can BAS116GWX replace BAS216 in existing designs?
No - BAS216 has higher VRRM (100 V) and different trr (4 ns), but significantly higher IR (100 nA). Substituting BAS116GWX would reduce leakage by >30× but compromise reverse voltage margin and high-speed switching capability, requiring circuit revalidation.
