Product details
Overview
BAT854CW,115 from Nexperia is a dual Schottky barrier diode in SOT323 (SC-70) package, rated for 40 V reverse voltage and 200 mA forward current per diode, featuring 420 mV typical forward voltage at 30 mA and 0.5 µA max reverse leakage at 25 V - deployed in ultra-high-speed switching and low-power handheld protection circuits.
For engineers reviewing the BAT854CW,115 datasheet, BAT854CW,115 pinout, BAT854CW,115 application, or BAT854CW,115 equivalent, key selection criteria include common-cathode dual-diode topology, guard ring stress protection, sub-1 µA reverse leakage, 20 pF capacitance at 1 V, and thermal resistance of 625 K/W on FR4 PCB.
Technical Context
This dual Schottky diode integrates two independent anodes (A1, A2) sharing a common cathode (K1/K2), enabling compact dual-path clamping or steering without cross-conduction. Its planar structure with integrated guard ring improves robustness against ESD and transient overstress.
Designed for low-voltage, high-efficiency operation, it delivers VF ≤ 550 mV at 100 mA and IR ≤ 0.5 µA at VR = 25 V, with junction temperature rated to 150 °C and ambient operating range from −65 °C to +150 °C - supporting reliable performance in space-constrained portable and industrial signal-path protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - maximum blocking capability per diode; defines safe operating margin in clamp/protection circuits. |
| Forward Voltage (VF) | 420 mV @ 30 mA, 25 °C - enables ultra-low conduction loss in battery-powered signal routing. |
| Reverse Current (IR) | 0.5 µA @ 25 V, pulsed - ensures minimal leakage-induced power drain in standby modes. |
| Diode Capacitance (Cd) | 20 pF @ 1 V, 1 MHz - supports <1 ns switching in RF and digital interface protection. |
| Thermal Resistance (Rth(j-a)) | 625 K/W on single-sided FR4 - requires careful PCB copper area design for sustained 200 mA operation. |
| Peak Forward Current (IFSM) | 1 A @ 8.3 ms half-sine - withstands short-duration surge events like ESD or inductive kickback. |
Pinout & Package
Encapsulated in SOT323 (SC-70), a 3-pin surface-mount plastic package measuring 2.0 mm × 1.25 mm × 0.95 mm with 1.3 mm lead pitch and tin-plated terminations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (Diode 1) | Input path for first Schottky junction; connects to protected signal or supply rail. |
| 2 | Anode (Diode 2) | Independent input path for second Schottky junction; enables dual-rail or differential clamping. |
| 3 | Common Cathode (K1/K2) | Shared output node; simplifies PCB layout by eliminating separate cathode traces and reducing parasitic inductance. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring protection | Integrated stress mitigation structure prevents premature breakdown under ESD or voltage transients. |
| Low VF across current range | 260 mV @ 1 mA to 550 mV @ 100 mA - maintains efficiency from microamp bias to full-rated load. |
| Ultra-small footprint | SOT323 (2.0 × 1.25 mm) - fits dense layouts in wearables, IoT sensors, and portable medical devices. |
| Low reverse leakage | ≤0.5 µA at 25 V - preserves battery life in always-on monitoring and sleep-mode applications. |
Applications
| USB Data Line Protection | Low-Voltage Rail Clamp |
|---|---|
Use Scenario: Protecting USB 2.0 D+/D− lines from ESD and overvoltage events in portable host/peripheral devices. IC Role / Device Role / Timing Role: Dual Schottky clamping diode with common cathode tied to VBUS or TVS ground reference. Use Value: 420 mV forward drop minimizes signal distortion; 20 pF capacitance avoids data-rate degradation up to 480 Mbps. |
Use Scenario: Clamping 3.3 V or 5 V logic rails against overshoot during hot-swap or level-shifting transitions. IC Role / Device Role / Timing Role: Bidirectional voltage limiter using two anodes referenced to different inputs and shared cathode to rail. Use Value: Guard ring ensures reliability under repeated 1 kV HBM ESD strikes; 1 A IFSM handles inductive turn-off spikes. |
| Handheld Device Power Sequencing | Signal Steering in Sensor Interfaces |
Use Scenario: Isolating backup battery paths from main supply in smart meters and medical monitors during brownout conditions. IC Role / Device Role / Timing Role: Dual blocking diode preventing backfeed between Li-ion cell and system regulator outputs. Use Value: 0.5 µA IR limits self-discharge to <1 µA per path - extends shelf life beyond 12 months. |
Use Scenario: Routing analog sensor outputs (e.g., thermistor, RTD) to multiple ADC inputs while avoiding crosstalk. IC Role / Device Role / Timing Role: Common-cathode dual diode acting as active signal selector with minimal forward offset. Use Value: Matched VF characteristics (<10 mV mismatch) ensure consistent gain and offset across channels. |
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 NSR20F40NXT5G | 40 V VR, 200 mA IF, but VF = 450 mV @ 30 mA; no guard ring; SOD-523 package (smaller, 1.3 × 0.85 mm). | Lacks integrated stress protection; higher VF increases conduction loss in battery-sensitive designs. | Prefer when board space is critical and ESD exposure is controlled; avoid in unshielded consumer ports. |
| Vishay SDURB140 | 40 V VR, 200 mA IF, VF = 490 mV @ 30 mA; common-cathode SOT-23 package; Rth(j-a) = 300 K/W (better thermal dissipation). | Larger footprint (3.0 × 1.4 mm); higher VF reduces efficiency in low-voltage rails. | Choose when thermal management dominates layout constraints and 490 mV VF is acceptable for system budget. |
Compared with NSR20F40NXT5G and SDURB140, BAT854CW,115 uniquely balances ultra-low VF, guard ring robustness, and SC-70 scalability - making it optimal for cost-sensitive, space-constrained, and ESD-prone portable interfaces where leakage and signal integrity are co-critical.

FAQ
Is BAT854CW,115 automotive qualified?
No. Per Nexperia's revision history (v.3, October 2024), BAT854CW,115 is explicitly non-automotive qualified. It lacks AEC-Q101 qualification and is not tested to automotive temperature or reliability standards. For automotive use, Nexperia recommends its -Q series alternatives such as BAT854CW-Q.
What is the meaning of the '83%' marking on BAT854CW,115?
The '83%' marking indicates the manufacturing site code, where '%' serves as a placeholder for a specific facility identifier. This code is used internally by Nexperia for traceability and does not affect electrical performance or packaging dimensions.
Can BAT854CW,115 be used in place of a single Schottky diode?
Yes, but only one diode section should be used with the unused anode left open or grounded - the common cathode must remain connected. Using both diodes simultaneously is required for dual-path functions like differential clamping; single-diode use forfeits the layout advantage of the shared cathode.
What is the recommended reflow profile for SOT323 mounting?
Nexperia specifies a standard JEDEC J-STD-020-compliant reflow profile: peak temperature 260 °C for ≤ 30 seconds, with ramp-up rate ≤ 3 °C/s and ramp-down rate ≤ 6 °C/s. The solder land pattern matches Figure 5 in the datasheet: 0.55 mm × 0.6 mm pads with 1.325 mm center-to-center spacing.
