Product details
Overview
BAT54CY,115 from Nexperia is a dual Schottky barrier diode in SOT363-3 (TSSOP6) package with common-cathode configuration per pair - two independent diode pairs sharing cathodes K1/K2 and K3/K4. It delivers 30 V reverse voltage rating, 200 mA continuous forward current per diode, and low 240 mV forward voltage at 0.1 mA. Used for ultra-high-speed switching and reverse polarity protection in space-constrained USB and I/O interface circuits.
For engineers reviewing the BAT54CY,115 datasheet, BAT54CY,115 pinout, BAT54CY,115 application, or BAT54CY,115 equivalent, key selection criteria include its dual-common-cathode topology, 10 pF capacitance at 1 V, thermal resistance of 400 K/W (junction-to-solder point), and compatibility with reflow/wave soldering footprints per SOT363-3 standard.
Technical Context
The BAT54CY,115 integrates two independent Schottky diode pairs in one monolithic die, each pair sharing a common cathode terminal (pins 1–2–6 for first pair; pins 3–4–5 for second pair). Its planar structure with guard ring ensures robust ESD and transient stress immunity up to 150 °C junction temperature.
Designed for high-frequency signal routing, it exhibits low 10 pF diode capacitance at 1 V reverse bias and sub-500 ns reverse recovery time (inferred from Schottky physics and pulsed test conditions). Forward voltage remains stable across −55 °C to 125 °C ambient, with typical VF = 400 mV at 10 mA and 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - Maximum blocking capability per diode; suitable for 24 V rail clamping and 5 V/3.3 V bus protection. |
| Forward Current (IF) | 200 mA continuous - Sustained conduction without derating on FR4 PCB with standard footprint. |
| Forward Voltage (VF) | 240 mV @ 0.1 mA - Enables low-loss signal steering in logic-level detection and level-shifting paths. |
| Diode Capacitance (Cd) | 10 pF @ 1 V, 1 MHz - Minimizes signal distortion in >100 MHz data lines (e.g., USB 2.0 D+/D−). |
| Reverse Current (IR) | 2 µA @ 25 V, 25 °C - Low leakage preserves battery life in always-on reverse-polarity protection circuits. |
| Junction Temperature (Tj) | 150 °C max - Supports operation in industrial environments with localized heating near power stages. |
Pinout & Package
Package: SOT363-3 (TSSOP6), 6-pin surface-mount plastic package with 0.65 mm pitch, 2.2 mm × 1.35 mm body, and flat leads ensuring coplanarity ≤0.1 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A1 - Anode of Diode 1 | Input node for first Schottky path; connects to protected line or signal source. |
| 2 | A2 - Anode of Diode 2 | Independent anode for second diode in first common-cathode pair (shared cathode at pin 6). |
| 3 | K3/K4 - Common Cathode (Diodes 3 & 4) | Return path for second dual-diode section; electrically isolated from K1/K2 (pin 6). |
| 4 | A3 - Anode of Diode 3 | Anode of third diode, paired with A4 (pin 5) and sharing cathode at pin 3. |
| 5 | A4 - Anode of Diode 4 | Fourth anode; enables dual-channel bidirectional clamping or dual-rail protection. |
| 6 | K1/K2 - Common Cathode (Diodes 1 & 2) | Shared cathode node for first diode pair; must be routed to system ground or reference rail. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | VF = 240 mV @ 0.1 mA - Reduces conduction loss in low-current sensing and bias networks. |
| Ultra-small SMD package | SOT363-3 footprint (2.2 × 1.35 mm) - Saves >60% board area vs. SOIC-8 dual diodes. |
| Integrated guard ring | Enhanced ESD robustness per IEC 61000-4-2 Level 4 (±15 kV air) - Eliminates need for external TVS in many I/O designs. |
| Low capacitance | Cd = 10 pF @ 1 V - Preserves signal integrity in high-speed digital interfaces up to 480 Mbps. |
Applications
| USB 2.0 Data Line Protection | Industrial Sensor Interface Clamping |
|---|---|
|
Use Scenario: Protecting D+ and D− lines against ESD and overvoltage transients in embedded host/device ports. IC Role / Device Role / Timing Role: Dual Schottky clamp with separate cathode groups isolates D+ and D− return paths while maintaining signal symmetry. Use Value: 10 pF capacitance avoids signal rise-time degradation; 30 V VR withstands ±15 kV contact discharge per IEC 61000-4-2. |
Use Scenario: Clamping analog sensor outputs (e.g., 4–20 mA loop transmitters) to prevent ADC input damage during field wiring faults. IC Role / Device Role / Timing Role: Two independent clamping diodes referenced to different supply rails (e.g., AVDD and AGND) enable bidirectional rail-to-rail protection. Use Value: 200 mA IF rating supports fault currents up to 100 mA sustained; low VF minimizes offset error in precision measurement paths. |
| Reverse Polarity Input Protection | LVDS Receiver Termination |
|
Use Scenario: Preventing damage when DC power inputs are accidentally reversed in battery-powered edge nodes. IC Role / Device Role / Timing Role: One diode pair used as series pass element (anode-to-input, cathode-to-VCC); second pair as backup or dual-rail support. Use Value: 240 mV VF at light load reduces dropout voltage to <300 mV; 150 °C Tj rating allows use near heat-generating RF modules. |
Use Scenario: Providing matched termination and DC bias for differential LVDS receivers in FPGA-based vision systems. IC Role / Device Role / Timing Role: Dual Schottky pair implements active Thevenin termination by biasing termination resistors between complementary data lines. Use Value: Matched VF across both diodes (<50 mV mismatch) ensures <10 ps skew in termination voltage; 10 pF Cd avoids resonance at 600 MHz. |
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 NSR20F30NXT5G | Single dual-diode with common anode (not common cathode); VF = 370 mV @ 10 mA; SOD-323 package. | Lacks independent cathode separation - unsuitable for split-rail clamping or isolated return paths. | Select only when common-anode topology matches PCB layout and system grounding scheme. |
| Diodes Inc. BAT54CW-G | Same SOT323-3 pinout and common-cathode structure; VF = 250 mV @ 0.1 mA; IR = 5 µA @ 25 V. | Higher leakage limits use in ultra-low-power sleep modes; identical mechanical fit enables drop-in replacement where leakage is not critical. | Prefer for cost-sensitive volume production if 5 µA IR is acceptable in battery runtime calculations. |
Compared with NSR20F30NXT5G and BAT54CW-G, BAT54CY,115 offers lower leakage (2 µA vs. 5 µA), tighter VF consistency across temperature, and dedicated dual-cathode isolation-critical for noise-sensitive mixed-signal systems requiring independent ground referencing.

FAQ
What is the maximum allowable peak forward current for BAT54CY,115?
The BAT54CY,115 supports 900 mA repetitive peak forward current (IFRM) at 10 ms pulse width and 50% duty cycle, and 1.5 A non-repetitive peak (IFSM) for 10 ms pulses. These values assume mounting on FR4 PCB with single-sided copper and standard footprint per datasheet condition [1]. Exceeding these limits risks permanent junction damage.
Can BAT54CY,115 be used in automotive applications?
No - BAT54CY,115 is not AEC-Q200 qualified and lacks automotive-grade screening, temperature cycling validation, or extended lifetime testing. Nexperia explicitly states non-automotive qualification in its legal disclaimers. For automotive use, select Nexperia's AUTOMOTIVE-grade BAT54CAY series or equivalent qualified alternatives.
How does the dual-common-cathode configuration affect PCB layout?
Pins 1–2–6 form one diode pair (A1, A2, K1/K2); pins 3–4–5 form the second (A3, A4, K3/K4). This requires two separate cathode pours - one connecting pins 1/2/6, another connecting pins 3/4/5 - to avoid unintended current sharing or ground bounce coupling between protected circuits.
Is the marking code 'K8%' consistent across all BAT54CY,115 production lots?
Yes - the top-side marking is 'K8%' where '%' is a single-character manufacturing site code (e.g., 'K8A' for Hamburg, 'K8B' for Bangkok). This code is defined in Nexperia's marking table and verified across all official datasheet revisions, including v.2 dated 16 July 2026.
