Product details
Overview
BAT54,215 from Nexperia is a planar Schottky barrier diode with integrated guard ring for stress protection, housed in an SOT23 (TO-236AB) surface-mount package. It delivers 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 - enabling ultra-high-speed switching in compact DC/DC converter feedback paths.
For engineers reviewing the BAT54,215 datasheet, BAT54,215 pinout, BAT54,215 application, or BAT54,215 equivalent, key selection criteria include low VF for efficiency-critical clamping, low Cd for high-frequency signal integrity, and n.c. terminal configuration for layout flexibility in space-constrained PCBs.
Technical Context
The BAT54,215 implements a single Schottky junction with guard ring structure to suppress edge breakdown under transient stress. Its low barrier height enables sub-800 mV conduction at 100 mA while maintaining 30 V VR capability - a trade-off optimized for speed over high-voltage blocking.
Thermal resistance is 500 K/W (junction-to-ambient, free air), and it operates across −55 °C to 150 °C ambient. The n.c. (pin 2) terminal eliminates parasitic coupling in high-isolation applications, distinguishing it from dual-diode variants like BAT54A/C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR | 30 V maximum reverse voltage - sets absolute upper limit for clamping or reverse polarity protection circuits |
| VF @ 100 mA | 800 mV typical - minimizes conduction loss in low-voltage power path switching |
| IR @ 25 V | 2 µA typical - ensures low standby leakage in battery-powered line termination |
| Cd @ 1 V | 10 pF typical - supports >100 MHz signal integrity in RF detector or high-speed logic clamp |
| trr | 5 ns typical - enables clean switching in >50 MHz clock line or data bus protection |
| Ptot | 250 mW maximum at 25 °C ambient - defines thermal derating envelope on standard FR4 PCB |
| Tj max | 150 °C junction temperature - constrains continuous current in thermally isolated layouts |
Pinout & Package
Package: SOT23 (TO-236AB), 3-terminal surface-mount plastic package, 2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Forward current entry point; connects to higher-potential node in clamping or rectification |
| 2 | Not Connected (n.c.) | Internally isolated - eliminates routing complexity and parasitic capacitance in single-diode use cases |
| 3 | Cathode (K) | Forward current exit point; ties to reference or return path; reverse-biased for clamping |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Prevents premature edge breakdown under ESD or voltage transients - improves reliability in unregulated input stages |
| Low forward voltage | 800 mV at 100 mA enables ≥95% efficiency in 3.3 V rail clamping without significant IR drop |
| Ultra-low capacitance | 10 pF at 1 V allows use in >100 MHz signal paths without measurable rise-time degradation |
| Fast reverse recovery | 5 ns trr supports clean switching in 20+ MHz digital bus termination without ringing or overshoot |
Applications
| Ultra-High-Speed Switching | Line Termination |
|---|---|
Use Scenario: High-frequency clock distribution networks requiring minimal capacitive loading and fast turn-off. IC Role / Device Role / Timing Role: Signal path clamp diode placed at receiver inputs to absorb reflections and limit overshoot. Use Value: 10 pF capacitance and 5 ns trr prevent signal integrity degradation up to 150 MHz. |
Use Scenario: RS-485 or CAN bus stubs where impedance matching must be maintained without adding series resistance. IC Role / Device Role / Timing Role: Passive termination element shunting excess energy to ground or VCC during differential transitions. Use Value: Low VF (800 mV) ensures clamping occurs before IC-level damage thresholds are exceeded. |
| Voltage Clamping | Reverse Polarity Protection |
Use Scenario: Input protection for 3.3 V or 5 V microcontroller I/O pins exposed to external connectors. IC Role / Device Role / Timing Role: Shunt clamp limiting transient voltage to < VF + Vrail, preventing latch-up or gate oxide damage. Use Value: 2 µA IR at 25 V ensures negligible quiescent current draw in always-on systems. |
Use Scenario: Battery-powered portable devices where accidental reverse battery insertion must not damage downstream circuitry. IC Role / Device Role / Timing Role: Series-connected anode-to-source diode blocking reverse current flow into the system. Use Value: 30 V VR rating covers common Li-ion (4.2 V) and 9 V battery configurations with margin. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSS40201MR6T1G | Same SOT23 package; VF = 750 mV @ 100 mA; Cd = 12 pF @ 1 V; trr = 4 ns | Slightly lower VF but higher capacitance - better for ultra-low-loss rectification, less ideal for >100 MHz signal lines | Select when minimizing conduction loss dominates over signal bandwidth requirements |
| Diodes Incorporated BAT54C-7-F | Dual-common-cathode configuration (2 diodes); VF = 800 mV; Cd = 10 pF; trr = 5 ns; same VR | Enables dual-rail clamping or complementary signal handling in one footprint - adds redundancy but increases layout area | Choose only when dual-diode functionality is required; otherwise BAT54,215 offers lower cost and simpler routing |
Compared with NSS40201MR6T1G and BAT54C-7-F, BAT54,215 uniquely combines single-diode simplicity, 10 pF capacitance, and guaranteed n.c. pin isolation - making it optimal for space-constrained, high-frequency clamping where layout parasitics must be minimized.

FAQ
Is BAT54,215 suitable for automotive applications?
No. BAT54,215 is explicitly non-automotive qualified per Nexperia's 2022 revision history. It lacks AEC-Q101 qualification, automotive-grade screening, and extended temperature validation beyond 150 °C junction. For automotive use, Nexperia offers BAT54 variants with "-Q" suffix and full AEC-Q101 compliance.
What does the "n.c." pin mean in practice?
Pin 2 is physically present but electrically unconnected internally. It must remain unconnected on the PCB - no soldering, routing, or grounding. This eliminates parasitic coupling paths and simplifies layout versus dual-diode packages, preserving signal integrity in high-frequency applications.
How does thermal resistance affect real-world current handling?
With Rth(j-a) = 500 K/W, dissipating 250 mW raises junction temperature by 125 K above ambient. At 25 °C ambient, Tj reaches 150 °C - its absolute maximum. Therefore, continuous IF must be reduced below 100 mA in still-air environments or with limited copper area to maintain safe operating temperature.
Can BAT54,215 replace BAT54A or BAT54C in existing designs?
No - BAT54,215 is a single-diode device with pin 2 n.c., whereas BAT54A is dual-anode and BAT54C is dual-cathode. Swapping requires schematic and layout changes. Electrical parameters match closely, but functional topology differs fundamentally.
