Product details
Overview
BAT74,215 from Nexperia is a planar Schottky barrier double diode in SOT143B package, featuring two electrically isolated diodes with integrated guard ring for stress protection. It delivers 800 mV forward voltage at 100 mA, 30 V reverse voltage rating, and 5 ns reverse recovery time-enabling ultra-high-speed switching in compact power management and signal clamping circuits.
For engineers reviewing the BAT74,215 datasheet, BAT74,215 pinout, BAT74,215 application, or BAT74,215 equivalent, key selection criteria include low VF for efficiency-critical biasing, dual-diode isolation for independent channel control, fast trr for high-frequency rectification, and SOT143B thermal performance under 125 °C junction operation.
Technical Context
This dual Schottky diode integrates two independent anode–cathode junctions in a single SOT143B package, with guard-ring protection to suppress edge breakdown under transient stress. Each diode operates up to 200 mA forward current and withstands 30 V reverse voltage independently.
Its 5 ns reverse recovery time and 10 pF capacitance at 1 V reverse bias support clean switching in RF detector, sample-and-hold, and high-speed logic clamping applications. Temperature coefficient of VF is −0.6 %/K, enabling predictable forward drop across −65 °C to +125 °C ambient range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VF @ 100 mA | 800 mV - Enables low-loss DC biasing and minimizes conduction loss in portable power rails. |
| trr | 5 ns - Supports >100 MHz switching in RF envelope detection and high-speed digital clamping. |
| Cd @ 1 V | 10 pF - Limits capacitive loading on high-impedance signal nodes such as op-amp inputs or ADC references. |
| VR | 30 V - Suitable for 24 V industrial bus clamping and 5 V/12 V logic-level protection without derating. |
| Ptot @ 25 °C | 230 mW - Allows continuous dual-diode operation in thermally constrained SMT layouts with no forced airflow. |
| Rth(j-a) | 500 K/W - Defines thermal rise of ~115 K at full 230 mW dissipation, guiding board copper area requirements. |
Pinout & Package
Encapsulated in a 4-lead SOT143B surface-mount plastic package (3.0 × 1.4 × 1.1 mm), the BAT74,215 provides mechanical robustness and standardized reflow compatibility per JEDEC MO-178.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Reference node for first Schottky junction; connects to ground or common return path in dual-rail clamp. |
| 2 | Cathode (Diode 2) | Independent cathode terminal enabling separate biasing or floating reference for second channel. |
| 3 | Anode (Diode 2) | Input node for second diode; used for bidirectional signal steering or independent input clamping. |
| 4 | Anode (Diode 1) | Primary input node for first diode; commonly tied to supply rail or signal source in series blocking. |
Key Features
| Feature | Design Value |
|---|---|
| Guard-ring protected junction | Suppresses edge leakage and improves ESD robustness (IEC 61000-4-2 Level 2) without external components. |
| Low VF at low IF | 240 mV @ 0.1 mA enables reliable turn-on in micropower sensor bias networks and wake-up circuits. |
| Electrically isolated diodes | Prevents cross-talk between channels in dual-supply monitoring or redundant signal paths. |
| Small SOT143B footprint | Reduces PCB area by 40% vs. SOIC-8 dual diodes while maintaining thermal performance via exposed pad alternatives. |
Applications
| USB Data Line Protection | RF Detector Input Clamp |
|---|---|
Use Scenario: Clamping ±15 V transients on USB 2.0 D+/D− lines during hot-plug events. IC Role / Device Role / Timing Role: Dual-channel voltage limiter-each diode clamps one data line to VDD and GND rails. Use Value: 800 mV VF ensures minimal signal distortion during normal 3.3 V operation; 5 ns trr avoids pulse smearing at 480 Mbps. |
Use Scenario: Limiting input swing to ±0.8 V at mixer IF port to prevent front-end saturation. IC Role / Device Role / Timing Role: AC-coupled bidirectional clamp-diodes conduct only during overvoltage peaks. Use Value: 10 pF capacitance preserves bandwidth beyond 500 MHz; guard ring prevents latch-up under RF stress. |
| DC-DC Converter Bootstrap Diode Pair | Industrial Sensor Signal Conditioning |
Use Scenario: Providing isolated bootstrap charging paths for high-side gate drivers in half-bridge converters. IC Role / Device Role / Timing Role: Dual independent anode-cathode paths-one per phase leg's bootstrap capacitor. Use Value: 200 mA per diode supports 1 A gate charge delivery at 100 kHz; low VF reduces bootstrap voltage droop. |
Use Scenario: Protecting 24-bit sigma-delta ADC inputs from field-wire surge in 4–20 mA loop receivers. IC Role / Device Role / Timing Role: Back-to-back clamping configuration-diodes shunt overvoltage to supply rails. Use Value: 30 V VR rating covers 36 V loop compliance; 2 μA IR at 25 V ensures <1 LSB error contribution at 1 MΩ input impedance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky double diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAT74,215 | Same die, identical electrical specs; differs only in marking code ('L4' vs 'L5') and traceable wafer lot origin. | No functional difference; accepted interchangeably in automotive AEC-Q200-compliant designs. | Select when requiring Nexperia's extended temperature grade validation (−65 °C to +150 °C storage). |
| NSR0230HT1G | Single-diode SOD-123 package; 30 V VR, 200 mA IF, but no dual-isolation or guard ring. | Requires two devices for dual-channel use; lacks integrated stress protection for harsh environments. | Choose only for space-constrained single-path clamping where dual isolation is unnecessary. |
Compared with SBAT74,215, BAT74,215 offers identical performance with standard qualification; versus NSR0230HT1G, it saves 35% board area and eliminates inter-device timing skew in synchronized clamping.

FAQ
What is the maximum continuous forward current per diode in BAT74,215?
The BAT74,215 supports 200 mA continuous forward current per diode at Tamb ≤ 25 °C, as specified in Table 5 (Limiting Values). When both diodes conduct simultaneously, total device current must not exceed 110 mA to maintain thermal safety within the 230 mW total power dissipation limit.
Does BAT74,215 have a built-in guard ring, and how does it affect reliability?
Yes-the BAT74,215 integrates a planar guard ring around each Schottky junction to suppress edge breakdown under voltage transients and electrostatic stress. This structure improves long-term reliability in industrial and automotive environments by reducing leakage drift and preventing premature failure during repetitive 30 V reverse-bias exposure.
Can BAT74,215 be used in reverse-series configuration for bipolar clamping?
Yes-its electrically isolated diodes allow back-to-back connection (anode-to-anode or cathode-to-cathode) to create symmetrical ±0.8 V clamping thresholds. The 240 mV VF at 0.1 mA ensures precise turn-on symmetry, and the 5 ns trr prevents overshoot during fast polarity reversals in AC-coupled signal paths.
What is the thermal resistance from junction to ambient, and how does it impact layout design?
The Rth(j-a) is 500 K/W in free air, meaning a 230 mW power dissipation causes ~115 K junction-to-ambient rise. To keep Tj ≤ 125 °C at 85 °C ambient, designers must ensure ≥ 12 mm² of 1-oz copper connected to pins 1 and 2 (cathodes) or use thermal vias-verified per Nexperia's SOT143B standard mounting conditions.
