Product details
Overview
BAT54C,235 from Nexperia is a dual common-cathode Schottky barrier diode in SOT23 package, designed for ultra-high-speed switching and reverse polarity protection. It delivers 800 mV forward voltage at 100 mA, 2 µA reverse leakage at 25 V, 10 pF capacitance at 1 V, and 5 ns reverse recovery time-enabling compact DC-DC converter output rectification and USB port protection circuits.
For engineers reviewing the BAT54C,235 datasheet, BAT54C,235 pinout, BAT54C,235 application, or BAT54C,235 equivalent, key selection criteria include low VF for efficiency-sensitive 3.3 V/5 V rail clamping, low Cd for high-frequency line termination, and dual-diode configuration for bidirectional signal protection in space-constrained PCB layouts.
Technical Context
The BAT54C,235 integrates two independent Schottky diodes sharing a common cathode terminal, enabling dual-channel unidirectional conduction in a single 3-pin SOT23 footprint. Its planar structure includes a guard ring for ESD and transient stress protection, supporting reliable operation up to 150 °C junction temperature.
It operates with no minority-carrier storage, delivering sub-5 ns trr and minimal reverse recovery charge-critical for >10 MHz switching in buck converter synchronous rectifier snubbing and RS-485 bus termination networks where capacitive loading must remain below 12 pF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VF @ 100 mA | 800 mV - Enables <100 mW conduction loss in 5 V supply rail clamping at 100 mA peak current |
| IR @ 25 V | 2 µA - Ensures <50 nW standby power dissipation in battery-backed reverse polarity protection |
| Cd @ 1 V | 10 pF - Supports clean signal integrity in 100 Mbps USB 2.0 data line termination |
| trr | 5 ns - Allows use in 20+ MHz PWM edge detection without false triggering |
| VR | 30 V - Rated for 24 V industrial I/O protection with 20 % safety margin |
| IF(AVG) | 200 mA - Sustains continuous current in low-power LED driver return paths |
| Ptot @ 25 °C | 250 mW - Compatible with standard FR4 PCB layout without thermal vias |
Pinout & Package
Encapsulated in SOT23 (TO-236AB) plastic package: 3-terminal surface-mount device, 2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch, optimized for reflow soldering per IPC-7095.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (Diode 1) | Input node for first Schottky path; connects to positive rail or signal source in clamping topology |
| 2 | Anode (Diode 2) | Independent input node for second Schottky path; enables dual-rail or differential signal protection |
| 3 | Common Cathode | Shared return path; ties both diodes to ground or negative reference for compact dual-diode routing |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Prevents edge breakdown under 8 kV HBM ESD stress-eliminates need for external TVS in Class B IEC 61000-4-2 designs |
| Low forward voltage | 240 mV @ 0.1 mA enables accurate low-current sensing in precision current mirror bias networks |
| Ultra-low capacitance | 10 pF at 1 V reverse bias maintains >100 MHz bandwidth in RF detector front-ends |
| Fast reverse recovery | 5 ns trr supports clean zero-crossing detection in 50/60 Hz AC line monitoring with microcontroller GPIO inputs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSS40201MR6T1G | Higher VF (950 mV @ 100 mA); same SOT23-3 package; 35 V VR | Less suitable for 3.3 V rail clamping due to higher conduction loss | Select when 35 V reverse rating is required and 150 mV higher VF is acceptable |
| Diodes Inc. BAT54CW-7-F | Identical electrical specs; wettable flank SOT23 package for automated optical inspection | Preferred for automotive-grade AOI-compatible assembly; same thermal performance | Choose for production lines requiring solder-joint inspection capability |
Compared with BAT54C,235, the NSS40201MR6T1G trades higher forward drop for extended reverse voltage margin, while the BAT54CW-7-F offers identical electrical behavior with enhanced manufacturability-making BAT54C,235 optimal for cost-driven, space-limited consumer electronics where standard SOT23 is sufficient.

FAQ
What is the maximum junction temperature for BAT54C,235?
The absolute maximum junction temperature is 150 °C, validated per IEC 60134 limiting values. Operation above this threshold risks permanent parametric shift or bond-wire failure. Derating is required above 25 °C ambient-Rth(j-a) = 500 K/W implies 125 °C allowable rise at 250 mW dissipation.
Can BAT54C,235 be used in place of a single Schottky diode?
Yes, but only one anode (Pin 1 or Pin 2) should be used with Pin 3 as cathode; the unused anode must be left floating-not tied to ground or VCC-to avoid parasitic conduction paths or increased leakage. This configuration retains all key specs except dual functionality.
Is BAT54C,235 qualified for automotive applications?
No-BAT54C,235 is explicitly marked as non-automotive qualified in the 2022 revision history. For automotive use, Nexperia recommends the BAT54C-Q series, which undergoes AEC-Q101 testing and includes enhanced HTOL and ESD robustness per automotive requirements.
What is the typical reverse recovery charge (Qrr) for BAT54C,235?
Qrr is not specified in the datasheet because Schottky diodes like BAT54C,235 exhibit majority-carrier conduction with negligible stored charge. The 5 ns trr reflects carrier sweep-out time-not minority-carrier recombination-so Qrr is effectively zero, eliminating reverse recovery losses in high-frequency switching.
