Product details
Overview
BAT54BR-G REG from Taiwan Semiconductor is a dual-channel Schottky barrier diode in SOT-363 package, rated for 30 V repetitive peak reverse voltage, 200 mA forward current, and 1.0 V forward voltage at 100 mA - used for high-speed reverse polarity protection and clamping in compact DC power rails.
For engineers reviewing the BAT54BR-G REG datasheet, BAT54BR-G REG pinout, BAT54BR-G REG application, or BAT54BR-G REG equivalent, key selection criteria include low VF at low-to-moderate IF, sub-5 ns reverse recovery time, 10 pF junction capacitance at 1 V, SOT-363 thermal resistance of 625°C/W, and RoHS/halogen-free compliance for consumer and industrial PCBs.
Technical Context
The BAT54BR-G REG integrates two independent Schottky diodes in a single SOT-363 (SC-70-6) surface-mount package with common-cathode configuration per device variant documentation. Its fast switching (trr ≤ 5 ns) and low forward voltage (VF ≤ 1.0 V @ 100 mA) stem from platinum-silicide or similar low-barrier metallization, enabling efficient clamping without significant conduction loss.
Thermal performance is defined by RθJA = 625°C/W under standard JEDEC conditions, and absolute maximum ratings include TJ = –65°C to +150°C and IFSM = 600 mA for surge immunity. The device meets J-STD-020 Level 1 moisture sensitivity and JESD201 Class 1A whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - supports clamping or reverse blocking in 24 V nominal systems without breakdown |
| IF | 200 mA continuous - suitable for low-power signal or bias rail protection |
| VF @ 100 mA | 1.00 V max - minimizes forward conduction loss in polarity guard circuits |
| trr | 5 ns max - enables reliable operation in >10 MHz switching applications |
| CT @ 1 V | 10 pF max - limits capacitive loading on high-speed signal lines |
| RθJA | 625 °C/W - requires careful thermal pad design for sustained 200 mA operation |
| IR @ 25 V | 2 μA max - ensures low leakage in battery-backed or standby circuits |
Pinout & Package
SOT-363 (SC-70-6) package with 6-pin lead frame, matte tin-plated terminals, UL 94V-0 molding compound, and 6.99 mg typical weight. Moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode A | Input node for first Schottky path; connects to protected supply or signal source |
| 2 | Cathode of Diode A | Common cathode node shared with Diode B; ties to reference rail or ground |
| 3 | NC | No internal connection - left floating or unused in PCB layout |
| 4 | NC | No internal connection - left floating or unused in PCB layout |
| 5 | Anode of Diode B | Input node for second Schottky path; enables dual-rail or redundancy use |
| 6 | Cathode of Diode B | Common cathode node shared with Diode A - electrically tied internally to Pin 2 |
Key Features
| Feature | Design Value |
|---|---|

| Low forward voltage drop | VF ≤ 1.0 V @ 100 mA reduces power loss and heat generation in always-on protection paths |
| Common-cathode dual-diode topology | Pins 2 and 6 internally shorted - simplifies PCB routing for dual-input/single-return configurations |
| RoHS & halogen-free compliance | Meets IEC 61249-2-21 and EU RoHS directives - qualified for consumer and industrial end-equipment |
| J-STD-020 Level 1 MSL | Unlimited floor life at ≤ 30°C/60% RH - eliminates bake requirement before reflow |
Applications
| USB Port Protection | Industrial Sensor Biasing |
|---|---|
Use Scenario: Preventing damage from accidental reverse insertion of USB cables into embedded host ports. IC Role / Device Role / Timing Role: Dual-anode, common-cathode Schottky clamp - each anode protects VBUS and D+/D− lines independently. Use Value: Sub-1 V VF prevents signal distortion on data lines while blocking reverse current up to 200 mA. | Use Scenario: Providing stable, low-loss bias to analog sensor bridges operating from 3.3 V or 5 V rails. IC Role / Device Role / Timing Role: Reverse polarity guard at sensor module input - placed upstream of LDO or op-amp supply pins. Use Value: 2 μA IR at 25 V ensures minimal quiescent drain in battery-powered sensors over 10+ year deployments. |
| DC-DC Converter Input Clamp | Automotive Body Control Module |
Use Scenario: Suppressing voltage spikes during hot-swap events on 12 V automotive DC-DC converter inputs. IC Role / Device Role / Timing Role: Fast-recovery clamping diode across input capacitor - shunts transients within 5 ns. Use Value: 600 mA IFSM withstands 100 ms surge pulses without degradation, supporting ASIL-B transient immunity. | Use Scenario: Protecting LIN bus transceiver power pins against battery reversal during service disconnect. IC Role / Device Role / Timing Role: Polarity guard on VCC line feeding LIN PHY ICs - mounted adjacent to connector. Use Value: SOT-363 footprint allows placement within 2 mm of connector, minimizing trace inductance and improving ESD robustness. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2004LKQ-7 | Single-channel SOT-23; VF = 0.45 V @ 100 mA; trr = 4 ns; RθJA = 300°C/W | Lacks dual-diode integration - requires two devices for same function; higher thermal efficiency but larger board area | Prefer when lower VF or better thermal dissipation is critical and space permits discrete placement |
| NSR0230P2T5G | Dual common-cathode SOT-563; VF = 0.45 V @ 100 mA; trr = 4 ns; IR = 10 μA @ 25 V | Higher leakage (10 μA vs. 2 μA); same pinout incompatible due to 5-pin SOT-563 vs. 6-pin SOT-363 | Select when tighter VF tolerance is needed and leakage budget allows ≥5× increase |
Compared with DMN2004LKQ-7 and NSR0230P2T5G, the BAT54BR-G REG provides optimal balance of dual-diode integration, ultra-low leakage, and JEDEC-standard SOT-363 compatibility - making it preferred for space-constrained, low-quiescent designs where reliability across temperature extremes matters.

FAQ
What is the pin configuration of BAT54BR-G REG?
The BAT54BR-G REG uses a SOT-363 package with six terminals: Pins 1 and 5 are anodes of two independent Schottky diodes; Pins 2 and 6 are internally shorted cathodes; Pins 3 and 4 are no-connect. This common-cathode dual-diode arrangement is confirmed in the official Taiwan Semiconductor datasheet revision H2111.
Is BAT54BR-G REG suitable for reverse polarity protection in 12 V automotive systems?
Yes, BAT54BR-G REG supports reverse polarity protection in 12 V systems: its 30 V VRRM provides 2.5× margin above nominal 12 V, 200 mA IF handles typical control-module loads, and –65°C to +150°C TJ range meets automotive under-hood requirements. Its 2 μA IR at 25 V also ensures minimal battery drain.
Does BAT54BR-G REG have a specified junction capacitance value?
Yes, BAT54BR-G REG has a maximum junction capacitance (CT) of 10 pF measured at 1 MHz and VR = 1 V, as specified in the Electrical Specifications table of the Taiwan Semiconductor datasheet. This low capacitance helps preserve signal integrity in high-speed clamping applications.
What is the thermal resistance of BAT54BR-G REG, and how does it affect layout?
BAT54BR-G REG has a junction-to-ambient thermal resistance (RθJA) of 625°C/W under standard JEDEC test conditions. This high value means PCB copper area and thermal vias beneath the exposed pad (if present) must be optimized - especially when operating near 200 mA continuously - to avoid exceeding the 150°C maximum junction temperature.
Is BAT54BR-G REG compliant with RoHS and halogen-free standards?
Yes, BAT54BR-G REG is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the Features section of the Taiwan Semiconductor datasheet. It carries no restricted substances above threshold limits and is qualified for use in environmentally regulated end equipment.
