Product details
Overview
BAT74V from Nexperia is a planar Schottky barrier double diode in SOT666 package, featuring two isolated dies with integrated guard rings for stress protection. It delivers 30 V reverse voltage rating, 200 mA forward current per diode, 800 mV forward voltage at 100 mA, 2 µA reverse leakage at 25 V, and 10 pF capacitance at 1 V - optimized for ultra-high-speed switching and polarity protection in space-constrained interfaces.
For engineers reviewing the BAT74V datasheet, BAT74V pinout, BAT74V application, or BAT74V equivalent, key selection criteria include low VF for efficiency-critical clamping, sub-10 pF Cd for RF line termination, dual-diode isolation for independent signal paths, and SOT666 coplanarity for reliable reflow assembly on high-density PCBs.
Technical Context
The BAT74V integrates two independent Schottky diodes on separate silicon dies within a single SOT666 package, each with guard-ring protection against electrical overstress. Its planar construction ensures stable junction characteristics across temperature, while flat leads improve thermal conduction and solder joint reliability.
Designed for pulsed operation (tp ≤ 300 µs, duty cycle δ = 0.02), it supports repetitive peak forward current up to 300 mA and non-repetitive surges to 600 mA. Thermal resistance Rth(j-a) is 416 K/W under standard FR4 mounting, defining its power handling in ambient-limited applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - defines maximum blocking capability per diode without breakdown in clamping or polarity protection circuits. |
| Forward Current (IF) | 200 mA continuous - sets steady-state current-handling limit for DC bias or low-duty-cycle signal paths. |
| Forward Voltage (VF) | 800 mV at 100 mA - enables low-loss voltage clamping and minimizes power dissipation in high-frequency switching nodes. |
| Reverse Leakage (IR) | 2 µA at 25 V - ensures minimal standby current in battery-powered polarity protection and level-shifting applications. |
| Diode Capacitance (Cd) | 10 pF at 1 V, 1 MHz - supports clean signal integrity in >100 MHz line termination and ESD front-end filtering. |
| Junction Temperature (Tj) | 125 °C max - constrains thermal design margin when operating near Ptot = 230 mW in sealed enclosures. |
| Package | SOT666 - 1.6 mm × 1.2 mm × 0.55 mm body with 0.5 mm pitch, enabling placement in <2.0 mm² board area. |
Pinout & Package
SOT666 is a 6-lead ultra-small surface-mount plastic package with flat leads, 0.5 mm pitch, and 1.6 mm × 1.2 mm footprint. Its coplanar lead geometry ensures consistent solder wetting and thermal performance on fine-pitch PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A1 | Anode of Diode 1 - connects to positive side of first Schottky path; used independently for dual-rail clamping or redundancy. |
| 2 | n.c. | Not connected - electrically isolated; no internal bond wire or die connection; must remain unconnected in layout. |
| 3 | K2 | Cathode of Diode 2 - common return node for second diode; enables independent cathode routing in split-bias designs. |
| 4 | A2 | Anode of Diode 2 - anode of second isolated Schottky; allows differential or mirrored signal conditioning paths. |
| 5 | n.c. | Not connected - electrically isolated; no internal bond wire or die connection; must remain unconnected in layout. |
| 6 | K1 | Cathode of Diode 1 - dedicated cathode terminal for Diode 1; supports separate grounding or biasing vs. K2. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | 800 mV at 100 mA - reduces conduction loss by >30% vs. standard silicon diodes in 3.3 V rail clamping. |
| Low capacitance | 10 pF at 1 V - preserves signal edge rate in USB 2.0 or LVDS line termination without added RC delay. |
| Guard ring integration | On-die stress protection - improves robustness against ESD transients up to ±8 kV HBM without external TVS. |
| Flat lead geometry | Enhanced coplanarity and thermal behavior - eliminates tombstoning risk and lowers junction-to-PCB thermal resistance. |
Applications
| USB Data Line Protection | LVDS Receiver Clamping |
|---|---|
|
Use Scenario: Protecting D+ and D− lines in USB 2.0 host ports against ESD and overvoltage events. IC Role / Device Role / Timing Role: Dual Schottky clamp providing bidirectional low-VF conduction to ground and VBUS rails. Use Value: 10 pF capacitance prevents signal degradation at 480 Mbps; dual-anode/cathode separation avoids cross-talk between data lanes. |
Use Scenario: Clamping differential inputs of LVDS receivers in industrial display interfaces. IC Role / Device Role / Timing Role: Independent diode pair limiting input swing to safe levels without loading the 100 Ω termination. Use Value: 800 mV VF ensures clamping threshold stays below receiver's absolute maximum rating while preserving common-mode range. |
| Redundant Power Rail OR-ing | Inverse Polarity Input Protection |
|
Use Scenario: Enabling seamless switchover between two 3.3 V backup supplies in telecom baseband modules. IC Role / Device Role / Timing Role: Two discrete Schottky paths acting as low-loss, fast-turn-on OR-ing elements. Use Value: 200 mA per diode supports parallel supply operation; guard ring withstands load-dump transients during switchover. |
Use Scenario: Preventing damage from reversed DC input in portable medical sensor modules powered by CR2032 coin cells. IC Role / Device Role / Timing Role: Single-diode path blocking reverse current while allowing normal forward conduction. Use Value: 2 µA IR at 25 V ensures <1 µA standby drain; SOT666 footprint fits within 3 mm × 3 mm battery connector zone. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky double diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB050M-30 | Single-diode SOD-323 package; 30 V VR, 500 mA IF, 500 mV VF @ 100 mA - higher current but no dual-diode isolation. | Lacks independent anode/cathode terminals; unsuitable for differential clamping or split-rail OR-ing. | Select only when single-path protection suffices and board area allows larger SOD-323 footprint. |
| NSR0230P2T5G | Dual-diode SOT-23 package; 30 V VR, 200 mA IF, 450 mV VF @ 100 mA - lower VF but no guard ring, 25 pF Cd. | Higher capacitance degrades >50 MHz signal integrity; no integrated stress protection limits ESD robustness. | Prefer where ultra-low VF dominates over RF performance or ruggedness requirements. |
Compared with BAT74V, RB050M-30 offers higher current but forfeits dual-diode flexibility, while NSR0230P2T5G trades guard ring and low-Cd for lower VF - making BAT74V optimal for compact, high-frequency, stress-prone dual-path designs.

FAQ
Is BAT74V automotive qualified?
No. BAT74V is explicitly marked as non-automotive qualified in the 2022 datasheet revision. It has not undergone AEC-Q101 testing or qualification for automotive environments, and Nexperia disclaims liability for use in safety-critical or automotive applications.
Can pins 2 and 5 be used as thermal pads or grounded?
No. Pins 2 and 5 are internally not connected - no bond wire or die connection exists. They must remain unconnected in PCB layout; grounding or thermal stitching violates the device's validated thermal model and may cause solder voiding or mechanical stress.
What is the maximum allowable solder temperature profile for BAT74V?
The only recommended soldering method is reflow. Peak temperature must not exceed 260 °C for ≤ 30 seconds, with ramp-up ≤ 3 °C/s and ramp-down ≤ 6 °C/s, per Nexperia's SOT666 reflow guidelines in Figure 5 of the datasheet.
Does BAT74V support bidirectional ESD protection?
Yes - when configured with A1/K1 and A2/K2 tied to complementary rails (e.g., VBUS and GND), its dual Schottky structure provides symmetrical clamping in both directions. However, effective protection requires proper PCB layout with minimized trace inductance to handle IEC 61000-4-2 transients.
