Product details

Overview

BAV23C-7 from Diodes Incorporated is a surface-mount dual high-voltage switching diode in SOT23 package, featuring 250 V repetitive peak reverse voltage (V_RRM), 400 mA forward current (I_FM), and 50 ns reverse recovery time (t_RR). It serves as a compact, low-leakage signal routing or clamping element in DC-DC converter feedback paths, battery protection circuits, and level-shifting interfaces.

For engineers reviewing the BAV23C-7 datasheet, BAV23C-7 pinout, BAV23C-7 application, or BAV23C-7 equivalent, key selection criteria include its dual-common-cathode configuration, 100 nA reverse leakage at 200 V/25°C, 1.0 V forward drop at 100 mA, and JEDEC-qualified reliability for portable and industrial power management designs.

Technical Context

This dual diode integrates two independent silicon junctions in a single SOT23-3 package with common cathode connection-confirmed by top-view marking diagrams and internal schematic in DS30042 Rev. 23–2. Its fast recovery (t_RR ≤ 50 ns) and low capacitance (C_T ≤ 5.0 pF at 0 V) support high-frequency switching up to ~10 MHz in flyback snubbers and signal clamping.

The device operates across –55°C to +150°C with thermal resistance R_θJA = 357°C/W on standard FR-4, and derates linearly above 25°C per Figure 1. Its 200 V working peak reverse voltage (V_RWM) and 250 V breakdown (V_(BR)R) enable robust overvoltage tolerance in 12–48 V rail monitoring and transient suppression.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	250 V - Withstands repetitive 250 V reverse transients without avalanche conduction.
I_FM	400 mA - Continuous forward current per diode; supports parallel-loaded dual-diode operation per Note 7.
t_RR	50 ns - Enables efficient switching in 1–10 MHz DC-DC converters and pulse shaping circuits.
C_T	5.0 pF - Low junction capacitance minimizes signal distortion in RF detector and sample-hold applications.
I_R	100 nA @ 200 V, 25°C - Ultra-low leakage preserves battery life in always-on sensor nodes and backup power paths.
P_D	350 mW - Maximum dissipation on standard FR-4 PCB; requires thermal derating above 25°C ambient.

IC Role / Device Role / Timing Role: Dual-anode clamping diode isolates battery terminals while sharing cathode return.

Use Value: 100 nA leakage at 200 V ensures <1 µA standby drain, extending shelf life beyond 12 months.

Use Scenario: Routes error amplifier output to optocoupler input in isolated flyback controllers.

IC Role / Device Role / Timing Role: Signal-level rectifier and transient suppressor on feedback loop.

Use Value: 50 ns t_RR avoids phase lag in 500 kHz–1 MHz control loops; 5.0 pF C_T prevents loop instability.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual high-voltage switching diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BAV23A-7-F	Same package and ratings, but common-anode configuration (vs. BAV23C's common-cathode).	Requires inverted PCB layout and reversed biasing in clamping circuits.	Select when cathode-referenced load switching is preferred over anode-referenced sourcing.
MMBD2836LT1G	Lower V_RRM (100 V), higher leakage (500 nA), same SOT23-3 footprint.	Suitable only for ≤24 V systems; not recommended for 48 V industrial or automotive use.	Choose only for cost-sensitive, low-voltage consumer applications where 250 V margin is unnecessary.

Compared with BAV23A-7-F and MMBD2836LT1G, BAV23C-7 offers unique common-cathode topology for grounded-load configurations, superior 250 V ruggedness for industrial 48 V rails, and lowest leakage among SOT23 dual diodes in its voltage class-making it optimal for battery-critical and high-reliability signal routing.

FAQ

What is the pin configuration of BAV23C-7?

BAV23C-7 uses a SOT23-3 package with Pin 1 = Anode of Diode 1, Pin 2 = Common Cathode, Pin 3 = Anode of Diode 2. This common-cathode arrangement is confirmed in the top-view diagram of DS30042 Rev. 23–2 and distinguishes it from the common-anode BAV23A variant.

Is BAV23C-7 suitable for automotive applications?

BAV23C-7 itself is not AEC-Q200 qualified; however, the automotive-compliant version BAV23CQ is explicitly listed in the datasheet as qualified to AEC-Q standards. For automotive designs, BAV23CQ must be specified-BAV23C-7 is intended for industrial and commercial applications meeting JEDEC reliability requirements.

How does BAV23C-7 differ from BAV23S-7-F?

BAV23S-7-F has a series-connected dual-diode configuration (anode-to-cathode), whereas BAV23C-7 uses common-cathode. This makes BAV23C-7 appropriate for parallel-load clamping, while BAV23S-7-F suits voltage-doubling or cascade rectification. Their electrical specs are identical, but circuit topology and PCB layout differ fundamentally.

What is the maximum operating temperature for continuous use?

BAV23C-7 is rated for continuous operation from –55°C to +150°C junction temperature. At ambient temperatures above 25°C, power dissipation must be derated linearly per Figure 1 in DS30042: 350 mW at 25°C drops to zero at ~125°C ambient on standard FR-4 board.
