Product details
Overview
BAV74 from Nexperia is a high-speed double diode with common cathode configuration in SOT23 package, designed for fast switching applications requiring low reverse recovery time (4 ns), 50 V continuous reverse voltage, and 450 mA repetitive peak forward current. It serves as a dual anode–common cathode switching pair in compact surface-mount circuits.
For engineers reviewing the BAV74 datasheet, BAV74 pinout, BAV74 application, or BAV74 equivalent, key selection criteria include reverse recovery time, thermal resistance (Rth(j-a) = 500 K/W), AEC-Q101 qualification, and dual-diode layout suitability for space-constrained signal routing and clamping.
Technical Context
The BAV74 integrates two independently operable planar silicon switching diodes sharing a single cathode terminal, enabling compact dual-path signal steering or level-clamping without inter-device mismatch. Its 4 ns trr and 1.5 pF capacitance at 0 V support >100 MHz signal integrity in thin-film and high-density PCB layouts.
Thermal design is constrained by Rth(j-sp) = 360 K/W to solder point and Ptot = 250 mW at 25 °C ambient, requiring FR4 PCB mounting with standard footprint per Figure 9. Junction temperature must remain ≤150 °C under double-diode load (125 mA max continuous).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse recovery time (trr) | 4 ns - enables clean edge transitions in >100 MHz digital signal routing and pulse shaping |
| Repetitive peak reverse voltage (VRRM) | 60 V - supports transient suppression in 24 V automotive and industrial control bus lines |
| Repetitive peak forward current (IFRM) | 450 mA - allows pulsed operation in logic-level clamping and protection circuits |
| Diode capacitance (Cd) | 1.5 pF at 0 V, 1 MHz - minimizes signal loading in RF detector and sampling applications |
| Forward voltage (VF) | 855 mV at 10 mA, 25 °C - ensures low conduction loss in high-frequency rectification paths |
| Junction-to-ambient thermal resistance (Rth(j-a)) | 500 K/W - defines derating curve for continuous operation above 25 °C ambient |
Pinout & Package
SOT23 plastic surface-mount package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm pin pitch), optimized for reflow soldering on FR4 PCBs with standard footprint per Figure 9.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of diode 1 (A1) | Independent input path for first switching channel; routed separately to avoid crosstalk |
| 2 | Anode of diode 2 (A2) | Independent input path for second switching channel; electrically isolated from A1 |
| 3 | Common cathode (CC) | Shared output node enabling OR-ing, clamping, or dual-input–single-output logic functions |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
| 4 ns reverse recovery time | Reduces switching losses and overshoot in high-frequency (>25 MHz) digital signal conditioning |
| 1.5 pF junction capacitance | Minimizes capacitive coupling between channels in RF front-end and sampling circuitry |
| Common-cathode dual-diode topology | Enables compact implementation of dual-input logic gates or bidirectional signal clamping |
Applications
| Automotive CAN Bus Protection | Digital Signal Clamping |
|---|---|
Use Scenario: Bidirectional transient suppression on CAN_H/CAN_L lines in 12 V vehicle networks. IC Role / Device Role / Timing Role: Dual-diode clamp with common cathode referenced to ground, absorbing ±60 V transients while preserving signal integrity. Use Value: Leverages 60 V VRRM and 4 ns trr to suppress ISO 7637-2 pulses without distorting 1 Mbps CAN edges. |
Use Scenario: Level-shifting and overvoltage clamping for 3.3 V/5 V logic signals interfacing mixed-voltage subsystems. IC Role / Device Role / Timing Role: Dual-anode clamp limiting inputs to safe thresholds using shared cathode tied to supply rail. Use Value: 855 mV VF at 10 mA ensures minimal forward drop during active clamping, preserving noise margins. |
| High-Speed Logic Gate Input Protection | RF Detector Diode Pair |
Use Scenario: Input protection for FPGA I/O banks exposed to ESD and signal reflections in test equipment interfaces. IC Role / Device Role / Timing Role: Dual-path ESD clamp with separate anodes for differential or parallel signal lines, common cathode to VCC or GND. Use Value: 1.5 pF capacitance prevents bandwidth degradation up to 500 MHz, critical for high-speed serial links. |
Use Scenario: Precision RF envelope detection in 868 MHz ISM-band receivers using matched diode pair. IC Role / Device Role / Timing Role: Two matched planar diodes sharing cathode for balanced demodulation and DC offset cancellation. Use Value: Matched trr and Cd ensure symmetrical response across both paths, reducing distortion in low-power detector outputs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed dual-diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99,215 | Same SOT23 package, but higher VRRM (70 V) and slightly slower trr (6 ns); VF = 1.25 V at 100 mA | Better suited for 48 V industrial bus protection where higher reverse margin is needed | Select when reverse voltage headroom >60 V is required and 2 ns slower recovery is acceptable |
| MMBD7000LT1G | Lower VF (715 mV at 1 mA), same trr (4 ns), but not AEC-Q101 qualified; Rth(j-a) = 625 K/W | Targeted at consumer electronics where automotive qualification is unnecessary | Choose for cost-sensitive non-automotive designs needing identical speed but relaxed reliability requirements |
Compared with BAV99,215 and MMBD7000LT1G, the BAV74 uniquely balances AEC-Q101 compliance, 4 ns trr, and 50 V VR in a single SOT23 footprint-making it optimal for space-limited automotive signal conditioning where both speed and qualification are mandatory.

FAQ
Is the BAV74 suitable for bidirectional TVS applications?
No-the BAV74 is a switching diode, not a TVS device. It lacks the avalanche breakdown characteristic and energy-handling capability required for transient voltage suppression. Its 60 V VRRM is a maximum blocking rating, not a clamping voltage. For bidirectional TVS, use dedicated devices like PESD5V0S1BA.
Can both diodes operate simultaneously at full rated current?
No-when both diodes conduct continuously, the maximum permissible forward current drops to 125 mA per diode due to thermal limits (Ptot = 250 mW). At 450 mA peak, only one diode may be pulsed per square-wave cycle with tp ≤ 1 µs and Tj held ≤150 °C.
What is the significance of the 'JA%' marking code?
'JA%' indicates the BAV74 is manufactured at Nexperia's Asia-Pacific facility ('JA'), with '%' representing a site-specific manufacturing code (e.g., JAB, JAC). This code enables traceability to wafer lot and assembly batch but does not affect electrical performance or package dimensions.
Does the common cathode configuration support reverse-biased operation of one diode while the other is forward-biased?
Yes-each anode operates independently. With CC grounded, applying +5 V to A1 forward-biases D1 while A2 remains reverse-biased at 0 V. The 30 nA IR at 25 °C ensures negligible leakage current coupling between paths under such asymmetric bias conditions.
