Product details
Overview
BAV23-7 from Diodes Incorporated is a dual surface-mount switching diode in SOT143 package, featuring two electrically isolated diode elements, 250 V repetitive peak reverse voltage (VRRM), 400 mA forward current (IF), and 50 ns reverse recovery time (trr), used in high-speed polarity protection and signal routing circuits.
For engineers reviewing the BAV23-7 datasheet, BAV23-7 pinout, BAV23-7 application, or BAV23-7 equivalent, key selection criteria include reverse breakdown voltage, switching speed, dual-element isolation, thermal derating behavior, and SOT143 footprint compatibility with space-constrained PCB layouts.
Technical Context
The BAV23-7 integrates two independent silicon planar epitaxial switching diodes in a single SOT143 package, enabling compact dual-path signal control without cross-coupling. Each element supports up to 250 V reverse blocking and exhibits low 100 nA leakage at 200 V and 25°C.
Its 50 ns reverse recovery time and 2.0 pF junction capacitance at 0 V bias support operation in 1–10 MHz switching applications. Thermal resistance of 312 °C/W (junction-to-ambient, FR-4 board) mandates power derating above 25°C ambient per Figure 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 250 V - Maximum repetitive reverse voltage each diode withstands without breakdown |
| trr | 50 ns - Time for diode to transition from conduction to full blocking under specified test conditions |
| IF | 400 mA - Continuous forward current per element; defines max DC load-handling capability |
| CT | 2.0 pF - Junction capacitance at 0 V bias and 1 MHz; impacts high-frequency signal integrity |
| RθJA | 312 °C/W - Thermal resistance limiting power dissipation on standard FR-4 PCB |
| VF @ 100 mA | 1.0 V - Forward voltage drop determining conduction loss and self-heating at typical signal levels |
| IR @ 200 V | 100 nA - Reverse leakage per element at rated DC blocking voltage and 25°C |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV21W-7-F (Diodes Inc.) | VRRM = 200 V; trr = 50 ns; same SOT143 package; lower reverse voltage rating | Not suitable for 250 V surge-prone industrial lines; acceptable for 12–24 V automotive logic inputs | Select when cost optimization outweighs need for 250 V margin and system-level surge immunity is externally managed |
| MMBD231LT1G (ON Semiconductor) | VRRM = 250 V; trr = 4 ns (faster); SOT23-3 package (single diode); requires two devices for dual function | Higher board area and routing complexity; faster switching enables >100 MHz RF detector use | Choose only if sub-10 ns recovery is mandatory and dual-element integration is not required |
Compared with BAV23-7, BAV21W-7-F trades 50 V reverse margin for cost, while MMBD231LT1G delivers superior speed but sacrifices monolithic dual integration-making BAV23-7 optimal for space-constrained, medium-speed dual-path protection where voltage headroom and layout simplicity are critical.

FAQ
What is the maximum junction temperature for continuous operation of the BAV23-7?
The BAV23-7 has an operating junction temperature range of –65°C to +150°C. For continuous operation at full 400 mA forward current, ambient temperature must be limited to ≤25°C on a standard FR-4 board due to its 312 °C/W thermal resistance; derating curves in Figure 1 define safe power limits at higher ambient temperatures.
Can the two diodes in the BAV23-7 share a common cathode or anode connection?
No-the BAV23-7 contains two fully electrically isolated diode elements. Pin 1 (Anode 1) and Pin 3 (Anode 2) are separate; Pin 2 (Cathode 1) and Pin 4 (Cathode 2) are also independent. No internal connection exists between either anodes or cathodes, enabling true dual-channel signal routing or protection.
Is the BAV23-7 suitable for use in automotive applications requiring AEC-Q101 qualification?
The BAV23-7 is not AEC-Q101 qualified. While its –65°C to +150°C operating temperature range meets automotive ambient requirements, Diodes Incorporated does not list it in their AEC-Q101 stress-tested portfolio. For automotive-grade dual diodes, consider the AEC-Q101-qualified BAV23A-7 variant or equivalent qualified alternatives.
How does the 2.0 pF junction capacitance affect performance in RF signal paths?
At 1.0 MHz and 0 V bias, the BAV23-7's 2.0 pF total capacitance introduces minimal reactance (>80 kΩ), making it suitable for RF detector and low-MHz mixer applications. However, above 10 MHz, this capacitance may attenuate signals or distort edges-designers should verify impedance matching and bandwidth impact using measured S-parameters or SPICE models.
