Product details
Overview
BAT54AD 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 clamping and polarity protection in compact DC power rails.
For engineers reviewing the BAT54AD REG datasheet, BAT54AD REG pinout, BAT54AD REG application, or BAT54AD REG equivalent, key selection factors include its 5 ns reverse recovery time, 2 μA max reverse leakage at 25 V, dual-diode configuration with common cathode topology, and moisture sensitivity level 1 compliance for standard reflow assembly.
Technical Context
The BAT54AD REG integrates two independent Schottky diodes sharing a common cathode terminal in a single SOT-363 surface-mount package, enabling compact dual-function implementation without discrete pairing. Its low VF (≤1.0 V @ 100 mA) and fast trr (≤5 ns) support efficient high-frequency switching in space-constrained layouts.
Designed for ambient operation from –65°C to +150°C, it delivers stable clamping performance across industrial temperature ranges while maintaining ≤10 pF junction capacitance at 1 V reverse bias - critical for minimizing signal distortion in RF-adjacent power domains.
Key Specifications

| IR @ 25 V | 2 μA - minimal leakage preserves battery life in always-on backup circuits |
| CT @ 1 V | 10 pF - low capacitance avoids signal coupling in mixed-signal PCB zones |
| TJ max | +150 °C - qualified for under-hood automotive and industrial control environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Diodes Inc. BAT54CWT | Same SOT-363 package, common-cathode configuration, but VF = 0.85 V @ 100 mA (typical) | Lower conduction loss suits higher-current (>150 mA) OR-ing; slightly tighter VF matching tolerance | Select BAT54CWT where <0.9 V VF is required at full load; verify IR spec matches 2 μA requirement |
| Nexperia PMEG3002AEB | SOT-363, single diode (not dual), VF = 0.51 V @ 100 mA, IR = 0.5 μA @ 25 V | Requires two devices for dual-path use; superior leakage performance for battery-backed circuits | Choose PMEG3002AEB when ultra-low IR dominates design priority and board area allows duplication |
Compared with BAT54CWT and PMEG3002AEB, the BAT54AD REG uniquely balances dual-diode integration, industry-standard 1.0 V VF ceiling, and 2 μA IR - making it optimal for cost-sensitive, space-constrained dual-rail protection where moderate leakage is acceptable.

FAQ
What is the pin configuration of the BAT54AD REG?
The BAT54AD REG uses a SOT-363 package with six terminals: pins 1 and 3 are anodes of the two Schottky diodes, pin 2 is their shared cathode, and pins 4–6 are internally unconnected. This common-cathode dual-diode layout enables compact reverse-polarity and OR-ing functions without external wiring. Always refer to the official Taiwan Semiconductor marking diagram for orientation verification before PCB layout.
Does the BAT54AD REG support reflow soldering without baking?
Yes, the BAT54AD REG has moisture sensitivity level 1 per J-STD-020, meaning it can be subjected to standard lead-free reflow profiles (e.g., JEDEC J-STD-020 Class 3) without prior dry-pack or baking. Its matte tin-plated leads meet J-STD-002 solderability requirements, ensuring reliable joint formation in automated assembly lines handling high-mix production.
What is the maximum junction temperature rating for BAT54AD REG?
The BAT54AD REG is rated for a maximum junction temperature of +150°C, with a storage temperature range of –65°C to +150°C. This rating is validated per absolute maximum ratings table in the H2111 datasheet revision and supports deployment in under-hood automotive modules, industrial motor drives, and enclosed power supplies where thermal derating must be calculated using RθJA = 625°C/W.
How does the reverse recovery time of BAT54AD REG compare to standard silicon diodes?
The BAT54AD REG exhibits a reverse recovery time (trr) of ≤5 ns, significantly faster than typical silicon PN-junction diodes (often >100 ns). This enables clean commutation in high-frequency switching circuits such as DC-DC converter snubbers and ESD-clamped data lines, eliminating tail current-induced shoot-through and reducing electromagnetic interference in sensitive analog sections.
Is BAT54AD REG suitable for battery-powered applications with low standby current requirements?
Yes, the BAT54AD REG draws ≤2 μA reverse leakage current at 25 V and 25°C, making it suitable for battery-powered systems where standby drain must be minimized - such as smart meters, wireless sensors, and IoT edge nodes. Its low IR value helps extend shelf life and operational runtime in coin-cell or Li-SOCl₂ powered designs where every nanoamp counts.
