Product details
Overview
BAT54J,115 from Nexperia is a planar Schottky barrier single diode with integrated guard ring for stress protection, housed in an SOD323F (SC-90) surface-mount package. It delivers 320 mV forward voltage at 1 mA, 30 V reverse voltage rating, and 10 pF capacitance at 1 V/1 MHz, enabling low-loss clamping and polarity protection in space-constrained portable electronics.
For engineers reviewing the BAT54J,115 datasheet, BAT54J,115 pinout, BAT54J,115 application, or BAT54J,115 equivalent, key selection criteria include forward voltage vs. current behavior, thermal resistance to solder point (55 K/W), junction temperature limit (150 °C), and SC-90 coplanarity performance under reflow.
Technical Context
The BAT54J,115 employs a planar Schottky junction with an integrated guard ring to suppress edge breakdown and improve robustness against transient overstress. Its low VF–IF characteristics stem from optimized metal–semiconductor interface design and thin epitaxial layer control.
Thermal performance is defined by Rth(j-sp) = 55 K/W to cathode solder point on FR4 PCB, supporting reliable operation up to 150 °C junction temperature. The device operates exclusively in forward conduction and reverse blocking modes-no switching control logic or integrated drivers are present.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Voltage (VF) | 320 mV at 1 mA pulsed - enables ultra-low-loss signal clamping in battery-powered receivers |
| Reverse Voltage (VR) | 30 V maximum - supports USB 2.0, I²C, and low-voltage logic line protection |
| Diode Capacitance (Cd) | 10 pF at 1 V / 1 MHz - preserves signal integrity in >100 MHz data lines |
| Forward Current (IF) | 200 mA continuous - sufficient for ESD clamp hold-off and moderate power rail protection |
| Junction Temperature (Tj) | 150 °C max - allows operation in sealed industrial enclosures without active cooling |
| Thermal Resistance (Rth(j-sp)) | 55 K/W to cathode solder point - enables predictable thermal rise on standard FR4 PCBs |
Pinout & Package
The BAT54J,115 is packaged in the SOD323F (SC-90) plastic SMD case: 1.7 mm × 1.25 mm × 0.7 mm body, flat leads for coplanarity, and cathode marked by a bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to ground or lower-potential node; marking bar identifies this terminal |
| 2 | Anode (A) | Connected to signal source or positive rail; current flows anode-to-cathode during forward bias |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Suppresses edge leakage and improves surge robustness without increasing die area |
| Low VF across IF range | 240–800 mV from 0.1–100 mA - reduces conduction loss in bidirectional signal paths |
| Flat lead geometry | Ensures ≤0.1 mm coplanarity - critical for void-free reflow on fine-pitch PCBs |
| Low thermal resistance to solder point | 55 K/W - enables direct thermal coupling to copper pour without thermal vias |
Applications
| Voltage Clamping | Line Termination |
|---|---|
Use Scenario: Protecting 3.3 V I²C bus lines from ESD transients and overshoot during hot-plug events. IC Role / Device Role / Timing Role: Passive clamping diode shunting excess voltage to ground before it reaches MCU pins. Use Value: 320 mV VF ensures minimal signal distortion; 10 pF Cd avoids capacitive loading of 400 kHz bus timing. | Use Scenario: Matching impedance on high-speed UART TX lines in handheld medical sensors. IC Role / Device Role / Timing Role: DC termination element providing stable bias while minimizing AC loading. Use Value: Low 10 pF capacitance maintains signal edge rate; flat leads ensure repeatable solder joint thermal mass. |
| Reverse Polarity Protection | Signal-Level Shifting |
Use Scenario: Preventing damage when CR2032 coin-cell batteries are inserted backward in wearable trackers. IC Role / Device Role / Timing Role: Series-connected anode-to-load diode blocking reverse current flow. Use Value: 200 mA IF rating handles peak sensor burst current; 30 V VR covers worst-case battery stack reversal. | Use Scenario: Level-shifting 1.8 V GPIO signals to 3.3 V peripherals in IoT edge nodes. IC Role / Device Role / Timing Role: Passive forward-biased diode dropping ~0.3 V between rails. Use Value: Tight VF distribution (240–320 mV at low IF) enables predictable 1.8 → 3.3 V translation without calibration. |
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 NSR0230HT1G | Same SOD-323 package; VF = 370 mV @ 1 mA; Cd = 12 pF @ 1 V | Slightly higher VF increases conduction loss in low-current clamping | Prefer BAT54J,115 where sub-330 mV VF is required for signal fidelity |
| Diodes Incorporated SD103AW-7-F | SOD-123 package (larger); VF = 450 mV @ 1 mA; Cd = 15 pF @ 1 V | Larger footprint limits use in ultra-compact wearables | Select BAT54J,115 when board space < 2.2 mm² per diode is mandatory |
Compared with NSR0230HT1G and SD103AW-7-F, the BAT54J,115 offers the lowest VF and smallest package among these three SMD Schottky diodes, making it optimal for miniaturized, low-power signal path protection where voltage headroom and layout area are constrained.

FAQ
What is the maximum continuous forward current for BAT54J,115?
The BAT54J,115 supports 200 mA continuous forward current at ambient temperatures ≤25 °C on an FR4 PCB with specified copper pad layout. Derating applies above 25 °C ambient, reaching zero allowable current at 150 °C junction temperature per its thermal resistance profile.
Does BAT54J,115 have automotive qualification?
No. The BAT54J,115 is explicitly designated as non-automotive qualified in its revision history and legal disclaimers. It lacks AEC-Q101 testing and is not warranted for use in safety-critical or automotive environments. Automotive alternatives require -Q suffix variants from Nexperia.
How is cathode identification implemented on BAT54J,115?
The cathode (Pin 1) is identified by a visible marking bar on the top surface of the SOD323F package. This aligns with the simplified outline in Nexperia's datasheet Figure 4 and confirms polarity during automated optical inspection and manual placement verification.
What soldering method is recommended for BAT54J,115?
Reflow soldering is the only recommended method, per Nexperia's thermal characteristics documentation. Wave or hand soldering is not advised due to thermal stress risks. The device's Rth(j-a) = 230 K/W in free air and sensitivity to localized heating necessitate controlled reflow profiles matching JEDEC J-STD-020.
