Product details
Overview
BAT54A,215 from Nexperia is a dual common-anode Schottky barrier diode in SOT23 package, designed for ultra-high-speed switching and reverse polarity protection. It features 30 V reverse voltage rating, 800 mV typical 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 use in USB line termination and low-voltage DC power rail clamping.
For engineers reviewing the BAT54A,215 datasheet, BAT54A,215 pinout, BAT54A,215 application, or BAT54A,215 equivalent, key selection criteria include its dual-diode common-anode configuration, low VF/low trr trade-off for high-frequency signal routing, thermal resistance of 500 K/W on FR4 PCB, and non-automotive qualification status per revision history.
Technical Context
The BAT54A,215 integrates two Schottky diodes sharing a common anode terminal (Pin 3), with isolated cathodes (Pins 1 and 2), forming a compact dual-diode structure optimized for bidirectional clamping or independent signal path protection. Its planar construction includes a guard ring for ESD and transient stress protection.
It operates within −55 °C to 150 °C ambient range, with junction temperature limited to 150 °C and total power dissipation capped at 250 mW at Tamb ≤ 25 °C. The device exhibits negligible minority-carrier storage, resulting in near-zero reverse recovery charge and sub-5 ns trr - critical for >100 MHz digital interface protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V maximum - sets absolute upper limit for clamping or blocking applications without breakdown. |
| Forward Voltage (VF) | 800 mV typical at 100 mA - enables low-loss voltage clamping in 3.3 V and 5 V systems. |
| Reverse Current (IR) | 2 µA typical at 25 V - ensures minimal leakage-induced power loss in battery-backed or low-quiescent circuits. |
| Diode Capacitance (Cd) | 10 pF at 1 V, 1 MHz - supports clean signal integrity in USB 2.0 and LVDS line termination. |
| Reverse Recovery Time (trr) | 5 ns typical - allows reliable operation in >100 MHz digital switching and pulse shaping. |
| Thermal Resistance (Rth(j-a)) | 500 K/W in free air on FR4 PCB - defines derating curve for continuous 200 mA forward current. |
| Peak Forward Current (IFSM) | 600 mA non-repetitive - supports surge tolerance during hot-plug or ESD event recovery. |
Pinout & Package
Encapsulated in SOT23 (TO-236AB) plastic surface-mount package: 3-terminal, 1.9 mm pitch, 2.9 mm × 1.3 mm × 1.0 mm body, standard footprint per Fig. 6 (reflow) and Fig. 7 (wave).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode 1) | Output node for first diode; connects to protected signal line or load return path. |
| 2 | K2 (Cathode 2) | Independent output node for second diode; enables dual-rail clamping or separate channel protection. |
| 3 | A1/A2 (Common Anode) | Shared anode tied to reference rail (e.g., VCC or ground); determines clamping polarity direction. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | 800 mV @ 100 mA - reduces conduction loss and self-heating in high-duty-cycle clamp circuits. |
| Low junction capacitance | 10 pF @ 1 V - preserves signal edge rate in high-speed data lines without RC filtering distortion. |
| Guard ring integration | Planar structure with integrated guard ring - improves ruggedness against EOS and localized ESD overstress. |
| Ultra-fast switching | 5 ns trr - eliminates tail current and cross-conduction risk in synchronous rectifier or OR-ing applications. |
Applications
| USB 2.0 Data Line Protection | Low-Voltage DC Power Rail Clamping |
|---|---|
|
Use Scenario: Protecting D+ and D− lines from ESD transients and overvoltage during hot-plug events in portable USB peripherals. IC Role / Device Role / Timing Role: Dual-cathode Schottky clamping diode with common anode tied to 3.3 V rail - provides bidirectional voltage limiting to ±0.3 V beyond rail. Use Value: 10 pF capacitance avoids signal integrity degradation at 480 Mbps; 5 ns trr prevents data eye closure from recovery lag. |
Use Scenario: Preventing reverse current flow and voltage inversion when multiple power sources (e.g., battery + USB) share a common load. IC Role / Device Role / Timing Role: Common-anode dual diode used as ideal diode OR-ing element - blocks reverse current while minimizing forward drop. Use Value: 800 mV VF at 100 mA reduces power loss by >40% vs. standard silicon diodes, extending battery runtime in portable devices. |
| LVDS Receiver Input Protection | RS-232 Transceiver Clamp Network |
|
Use Scenario: Safeguarding differential receiver inputs against I/O overvoltage and ESD in industrial sensor interfaces. IC Role / Device Role / Timing Role: Two independent cathodes (Pins 1 & 2) connected to LVDS+ and LVDS−, common anode to 3.3 V - forms symmetrical rail-to-rail clamp. Use Value: Matched VF and Cd across both diodes ensure balanced common-mode rejection; 2 µA IR avoids DC offset drift in high-impedance receivers. |
Use Scenario: Limiting RS-232 driver output swing to safe levels for mixed-voltage system interfacing (e.g., 3.3 V MCU with ±12 V transceiver). IC Role / Device Role / Timing Role: Cathodes tied to TX/RX lines, common anode to 3.3 V - clamps negative excursions to −0.3 V and positive to +3.6 V. Use Value: 30 V VR rating accommodates RS-232's ±12 V swing with margin; SOT23 footprint enables compact placement near connector pins. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual common-anode Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSR0230HT1G | Single diode, SOD-123, 30 V VR, 420 mV VF @ 100 mA - lower VF but no dual configuration. | Requires two devices for dual-line protection; lacks integrated common-anode topology. | Select when lowest possible forward drop is critical and board space permits discrete duplication. |
| Vishay SDM10U30-7 | Dual common-cathode (not common-anode), SOT23, 30 V VR, 550 mV VF @ 100 mA - inverted polarity configuration. | Requires redesign of clamp rail connection (cathodes to rail instead of anode); not drop-in. | Choose only if existing layout uses cathode-to-rail clamping and rework is acceptable. |
Compared with NSR0230HT1G and SDM10U30-7, BAT54A,215 uniquely delivers dual-channel protection in a single SOT23 with common-anode architecture - reducing component count and layout complexity for rail-symmetric clamping without sacrificing speed or leakage performance.

FAQ
Is BAT54A,215 qualified for automotive applications?
No. Per the 2022 revision history, BAT54A,215 was explicitly changed to non-automotive qualification. Automotive-grade alternatives (e.g., BAT54A-Q) are available from Nexperia but require separate part numbering and qualification documentation. This part is intended for industrial, computing, and consumer applications only.
What is the correct orientation for mounting BAT54A,215 on PCB?
Pin 1 (K1) is marked with a dot or notch on the package top side; Pin 3 (common anode) is the rightmost terminal when the marking side faces up and the tab/polarity indicator is left-aligned. Reflow soldering footprint matches Figure 6 in the datasheet: 0.6 mm pad width, 0.7 mm length, 1.9 mm center-to-center pitch.
Can BAT54A,215 be used for 5 V logic-level clamping?
Yes. With common anode tied to 5 V and cathodes connected to signal lines, it clamps negative excursions to ~−0.8 V and limits positive overshoot to ~5.8 V. Its 30 V VR rating and 2 µA IR at 25 V ensure safe operation under 5 V rail conditions, provided peak transient energy remains within IFSM (600 mA) limits.
How does BAT54A,215 differ from BAT54C or BAT54S?
BAT54A has a common-anode configuration (Pins 1&2 = cathodes, Pin 3 = shared anode); BAT54C is common-cathode (Pins 1&2 = anodes, Pin 3 = shared cathode); BAT54S is series-connected (Pin 1 = anode, Pin 2 = center tap, Pin 3 = cathode). These configurations are electrically distinct and not interchangeable without circuit redesign.
