Product details
Overview
BAT54S,215 from Nexperia is a dual common-cathode Schottky barrier diode in SOT23 package, featuring 30 V reverse voltage rating, 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-used for ultra-high-speed switching and reverse polarity protection in USB and I/O interface circuits.
For engineers reviewing the BAT54S,215 datasheet, BAT54S,215 pinout, BAT54S,215 application, or BAT54S,215 equivalent, key selection criteria include low VF for power-sensitive signal clamping, sub-10 pF junction capacitance for high-frequency line termination, and dual-diode configuration enabling compact dual-rail protection without discrete pairing.
Technical Context
The BAT54S,215 integrates two independent Schottky diodes sharing a common cathode (Pin 2), configured as a single-package dual-diode solution optimized for bidirectional signal integrity and rail-to-rail clamping. Its planar structure with guard ring enhances ESD robustness and thermal stability up to 150 °C junction temperature.
Designed for pulsed operation (δ ≤ 0.02, tp ≤ 300 µs), it delivers consistent VF across 0.1–100 mA forward current range (240–800 mV) and maintains <2 µA IR up to 25 V reverse bias-enabling reliable low-loss clamping in 3.3 V and 5 V digital interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - supports clamping in 24 V industrial I/O and 5 V logic rails without breakdown |
| Forward Voltage (VF) | 800 mV @ 100 mA - minimizes conduction loss in high-duty-cycle protection paths |
| Reverse Leakage (IR) | 2 µA @ 25 V - ensures negligible standby current in battery-backed systems |
| Junction Capacitance (Cd) | 10 pF @ 1 V - preserves signal edge integrity up to ~350 MHz in USB 2.0 and LVDS lines |
| Reverse Recovery Time (trr) | 5 ns - enables clean switching in >100 MHz digital signal routing and termination |
| Peak Forward Current (IFSM) | 600 mA - withstands transient surge events such as ESD-induced current spikes |
| Thermal Resistance (Rth(j-a)) | 500 K/W - requires minimal PCB copper area for thermal management in space-constrained layouts |
Pinout & Package
Encapsulated in SOT23 (TO-236AB) plastic surface-mount package: 3-terminal, 1.9 mm pitch, 2.9 × 1.3 × 1.0 mm body, FR4-compatible footprint per Fig. 6 (reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (Diode 1) | Input node for first Schottky path; connects to protected signal line or positive rail |
| 2 | Cathode (Diode 2) | Shared cathode node; ties both diodes to reference (e.g., GND or negative rail) |
| 3 | Cathode (Diode 1) / Anode (Diode 2) | Common terminal enabling dual-direction clamping: Pin 1→2 protects positive transients; Pin 3→2 protects negative transients |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | 800 mV max at 100 mA enables efficient clamping in 3.3 V systems with <0.5 V headroom loss |
| Low junction capacitance | 10 pF at 1 V allows use in 480 Mbps USB 2.0 data lines without signal distortion |
| Guard ring integration | Enhances ruggedness against ESD stress (IEC 61000-4-2 level 4 compatible when properly laid out) |
| Dual-diode common-cathode topology | Reduces board area by 40% vs. two discrete SOT23 diodes while maintaining independent anode routing |
Applications
| USB Data Line Protection | I/O Port Clamping |
|---|---|
Use Scenario: Protecting D+ and D− lines of USB 2.0 peripherals from ESD and overvoltage events during hot-plug insertion. IC Role / Device Role / Timing Role: Dual Schottky clamp conducting transient energy to ground while preserving signal rise/fall times. Use Value: 5 ns trr and 10 pF Cd maintain <10% signal distortion at 480 Mbps, meeting USB-IF eye diagram compliance. | Use Scenario: Safeguarding microcontroller GPIO pins connected to external sensors or actuators exposed to field wiring noise. IC Role / Device Role / Timing Role: Bidirectional voltage limiter referenced to MCU VDD/GND rails using shared cathode architecture. Use Value: 30 V VR and 2 µA IR ensure compatibility with 24 V industrial sensor inputs while drawing negligible quiescent current. |
| RS-485 Bus Termination | Reverse Polarity Input Protection |
Use Scenario: Providing AC-coupled termination on differential RS-485 receiver inputs to suppress common-mode ringing. IC Role / Device Role / Timing Role: Low-Cd Schottky pair acting as high-frequency shunt to stabilize bus impedance above 10 MHz. Use Value: 10 pF capacitance avoids resonance with 120 Ω termination, preventing overshoot in multi-drop networks. | Use Scenario: Preventing damage to DC-powered modules (e.g., PMICs, LDOs) when input connector is miswired. IC Role / Device Role / Timing Role: Series-connected Schottky (anode to supply, cathode to load) blocking reverse current flow. Use Value: 800 mV VF adds only 0.8 V dropout at full load, outperforming standard silicon diodes by >500 mV. |
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 NSR0230HT1G | Single diode in SOD-123; no dual configuration; VF = 450 mV @ 200 mA | Requires two devices for dual-rail protection; higher board area and assembly cost | Select when ultra-low VF dominates over integration and layout simplicity |
| Vishay SDM10030C-7-F | Common-anode dual Schottky; VF = 520 mV @ 100 mA; VR = 30 V; Cd = 30 pF | Less suitable for bidirectional clamping; higher capacitance limits >100 MHz use | Prefer for unidirectional rail-to-rail clamping where lower VF offsets higher Cd penalty |
Compared with NSR0230HT1G and SDM10030C-7-F, BAT54S,215 uniquely balances dual-diode integration, 5 ns speed, and 10 pF capacitance-making it optimal for space-constrained, high-speed bidirectional protection where layout efficiency and signal fidelity are co-prioritized.

FAQ
What is the maximum continuous forward current rating for BAT54S,215?
The BAT54S,215 has a maximum continuous forward current (IF) of 200 mA at Tamb = 25 °C, derating linearly above that ambient temperature. This rating assumes proper PCB thermal relief per Nexperia's SOT23 footprint guidelines (FR4, single-sided copper, tin-plated). Exceeding this limit risks thermal runaway due to Schottky's positive temperature coefficient of VF.
Does BAT54S,215 support automotive applications?
No-BAT54S,215 is explicitly designated as non-automotive qualified per Nexperia's 2022 revision history. It lacks AEC-Q101 qualification, automotive-grade screening, and extended temperature validation beyond −55 °C to +150 °C ambient. For automotive use, Nexperia offers the BAT54S-Q series with full AEC-Q101 certification and enhanced reliability testing.
How is the common-cathode configuration used in reverse polarity protection?
In reverse polarity protection, Pin 1 (A1) connects to the input supply, Pin 2 (K2) to system ground, and Pin 3 (K1/A2) to the load. With correct polarity, Diode 1 (A1→K2) conducts; with reversed polarity, Diode 2 (A2→K2) is reverse-biased and blocks current. This leverages the shared cathode to achieve single-point grounding and eliminate floating nodes.
Can BAT54S,215 be used in place of BAT54C or BAT54A?
No-BAT54S,215 has a common-cathode pinout (Pin 2 = K1/K2), whereas BAT54C is common-anode (Pin 2 = A1/A2) and BAT54A is series-connected (Pin 1 = A1, Pin 2 = K1/A2, Pin 3 = K2). Swapping them without circuit redesign causes functional failure: incorrect biasing, unintended conduction paths, or open-circuit behavior in clamping configurations.
