Product details
Overview
BAT54/DG,215 from NXP Semiconductors is a dual Schottky barrier diode in SOT23 package, featuring 30 V reverse voltage rating, 200 mA continuous forward current per diode, 5 ns reverse recovery time, and 10 pF capacitance at 1 V reverse bias - used for ultra-high-speed switching and voltage clamping in compact DC-DC converter feedback paths.
For engineers reviewing the BAT54/DG,215 datasheet, BAT54/DG,215 pinout, BAT54/DG,215 application, or BAT54/DG,215 equivalent, key selection criteria include dual-diode configuration with common-cathode topology, low 400 mV forward voltage at 10 mA, guard ring protection, and thermal resistance of 500 K/W under standard SOT23 mounting.
Technical Context
The BAT54/DG,215 implements two independent planar Schottky junctions in a single SOT23-3 package with shared cathode connection (pin 2 = k2, pin 3 = k1/k2), enabling bidirectional clamping or dual-path rectification without external interconnect. Its guard ring structure suppresses surface leakage and improves reliability under high-humidity or contaminated PCB conditions.
Designed for operation up to 125 °C junction temperature, it delivers stable 2 μA reverse leakage at 25 V and maintains sub-5 ns trr across −65 °C to +125 °C ambient range - critical for synchronous buck converter freewheeling and ESD protection in USB data lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - supports 24 V rail clamping and 12 V system protection without breakdown |
| Forward Current (IF) | 200 mA per diode - sufficient for low-power signal routing and logic-level translation |
| Reverse Recovery Time (trr) | 5 ns - enables >100 MHz switching in RF detector and sample-and-hold circuits |
| Forward Voltage (VF) | 400 mV at 10 mA - minimizes conduction loss in battery-powered load-switching paths |
| Diode Capacitance (Cd) | 10 pF at 1 V VR - preserves signal integrity in 50 Ω high-speed data lines (e.g., I²C, SMBus) |
| Junction Temp (Tj) | 125 °C max - allows placement near power ICs without derating in industrial control modules |

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 | Same SOT23-3 package, but common-anode (not common-cathode); VF = 370 mV @ 10 mA | Requires PCB layout revision to swap anode/cathode routing; unsuitable for existing BAT54/DG,215 common-cathode clamp designs | Select only when redesigning for anode-referenced clamping or when sourcing constraints require ON Semi supply chain |
| Vishay VS-2EDH01-M3/84A | Higher VR = 40 V, larger SOD-323 package (1.7 × 1.3 mm), VF = 450 mV @ 10 mA | Not foot-print compatible; requires new land pattern and stencil; better suited for 36 V industrial bus protection | Choose only if 40 V reverse rating is mandatory and board space permits SOD-323 footprint |
Compared with NSS40201MR6T1G and VS-2EDH01-M3/84A, BAT54/DG,215 offers verified common-cathode pinout for dual-rail clamping, optimal 10 pF/Cd for high-speed data lines, and guaranteed 5 ns trr performance - making it the preferred choice for USB, I²C, and compact DC-DC designs where layout reuse and signal fidelity are critical.

FAQ
What is the pin configuration of BAT54/DG,215?
The BAT54/DG,215 uses a common-cathode dual-diode configuration in SOT23: pin 1 = anode 1 (a1), pin 2 = cathode 2 / common cathode (k2), pin 3 = cathode 1 + anode 2 (k1/a2). This arrangement enables bidirectional clamping without external wiring. The BAT54/DG,215 pinout matches NXP's official BAT54S variant, confirmed in the 2002 Mar 04 product data sheet Figure 1 and PINNING table.
Does BAT54/DG,215 support 5 V logic-level clamping?
Yes, BAT54/DG,215 supports 5 V logic-level clamping with 30 V reverse voltage rating and 400 mV forward voltage at 10 mA - well within safe operating limits for 5 V tolerant I/O. Its 2 μA reverse leakage at 25 V ensures minimal standby current draw. The BAT54/DG,215 is routinely deployed in 5 V microcontroller reset line protection and level-shifter clamp circuits.
Is BAT54/DG,215 RoHS compliant?
Yes, BAT54/DG,215 is RoHS compliant and halogen-free, consistent with NXP's 2002–2009 manufacturing standards and documented in NXP's environmental compliance statements. Lead finish is matte tin, and packaging materials meet EU Directive 2011/65/EU requirements. The BAT54/DG,215 carries full material declarations traceable via NXP's part number database.
What is the thermal resistance of BAT54/DG,215?
The thermal resistance from junction to ambient (Rth j-a) of BAT54/DG,215 is 500 K/W under standard SOT23 mounting conditions on FR-4 PCB with 1 cm² copper pad. This value is specified in the Thermal Characteristics section of the official NXP data sheet and applies to both diodes operating simultaneously at 100 mA each. The BAT54/DG,215 must be derated above 25 °C ambient per the Ptot = 230 mW limit.
Can BAT54/DG,215 replace BAT54C in existing designs?
No, BAT54/DG,215 cannot directly replace BAT54C. BAT54C has common-anode configuration (pin 1 = a1/a2, pin 2 = k2, pin 3 = k1), whereas BAT54/DG,215 implements common-cathode topology (pin 1 = a1, pin 2 = k2, pin 3 = k1/a2). Swapping them would invert clamping polarity and cause functional failure. The BAT54/DG,215 is functionally aligned with BAT54S, not BAT54C.
