Product details

Overview

BAV23S,235 from Nexperia is a dual high-voltage switching diode in SOT23 package, configured as two independent diodes sharing a common terminal (pin 3 = K1/A2). It delivers V_RRM = 250 V, trr ≤ 50 ns, and C_d ≤ 2 pF per diode, enabling fast, low-capacitance switching in high-voltage DC-DC converters and flyback snubbers.

For engineers reviewing the BAV23S,235 datasheet, BAV23S,235 pinout, BAV23S,235 application, or BAV23S,235 equivalent, this device supports dual-diode topologies requiring shared-cathode/anode routing, low leakage (<100 nA at 200 V), and thermal robustness up to T_j = 150 °C on FR4 PCBs.

Technical Context

The BAV23S,235 integrates two discrete silicon switching diodes in a single SOT23-3 package with pin 1 = A1, pin 2 = K2, and pin 3 = K1/A2 - enabling series-connected or common-node configurations. Its epitaxial construction ensures consistent trr ≤ 50 ns under IF = 10 mA / IR = 10 mA test conditions.

Thermal performance is defined for FR4 PCB mounting: R_th(j-a) = 500 K/W (free air) and R_th(j-sp) = 360 K/W (solder point), with P_tot = 250 mW at T_amb ≤ 25 °C. Reverse leakage remains ≤100 µA at VR = 200 V and T_j = 150 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	250 V repetitive peak reverse voltage - supports 200 V DC bus designs with 25 % safety margin
trr	≤50 ns reverse recovery time - enables >1 MHz switching in SMPS without excessive switching loss
C_d	≤2 pF diode capacitance at 0 V / 1 MHz - minimizes capacitive coupling in high-frequency gate-drive or signal-clamp paths
I_F	125 mA continuous forward current per diode - suitable for low-power auxiliary supplies and bias networks
I_FRM	625 mA repetitive peak forward current - handles pulsed loads in relay drivers or LED strobes
R_th(j-a)	500 K/W junction-to-ambient thermal resistance - requires minimal copper area for thermal management on standard FR4

Pinout & Package

Encapsulated in SOT23 (TO-236AB) plastic SMD package: 3-terminal, 1.9 mm pitch, 2.9 × 1.3 × 1.0 mm body, optimized for reflow soldering on standard FR4 PCBs.

Pin/Terminal	Circuit Role	Design Meaning
1	Anode of Diode 1 (A1)	Input node for first diode; connects to high-side switch or positive rail in clamp configuration
2	Cathode of Diode 2 (K2)	Output node for second diode; routes to load or feedback network in dual-path topology
3	Cathode of Diode 1 (K1) and Anode of Diode 2 (A2)	Shared internal node - enables series connection (A1–K1/A2–K2) or common-cathode/anode layout

Key Features

Feature	Design Value
High-speed switching	trr ≤ 50 ns ensures minimal tail current and reduced EMI in >500 kHz power stages
Low leakage current	IR ≤ 100 nA at VR = 200 V preserves efficiency in high-impedance bias and sensing circuits
Dual-diode integration	Single SOT23 footprint replaces two discrete diodes - saves 30 % board area vs. separate SOT23 devices
Low junction capacitance	Cd ≤ 2 pF limits displacement current in fast-edge applications like pulse shaping or RF detection

Applications

Switch-Mode Power Supply Snubbers

High-Voltage Signal Clamping

Use Scenario: Suppressing voltage spikes across MOSFET drains in 200 V flyback converters.

IC Role / Device Role / Timing Role: Fast-recovery clamping diode absorbing turn-off energy into RC network.

Use Value: trr ≤ 50 ns prevents secondary breakdown; V_RRM = 250 V accommodates 200 V input + 25 % transients.

Use Scenario: Protecting ADC inputs from ±200 V transient overvoltage in industrial sensor interfaces.

IC Role / Device Role / Timing Role: Bidirectional clamping element limiting input swing to safe range using dual-diode back-to-back configuration.

Use Value: Low C_d ≤ 2 pF avoids signal distortion; IR ≤ 100 nA prevents loading of high-Z sensor outputs.

Relay Coil Suppression

High-Speed Logic-Level Translation

Use Scenario: Dissipating inductive kickback from 24 V/125 mA relay coils in PLC I/O modules.

IC Role / Device Role / Timing Role: Freewheeling diode providing low-loss path during coil de-energization.

Use Value: I_F = 125 mA rating matches typical relay hold current; compact SOT23 fits dense I/O layouts.

Use Scenario: Level-shifting TTL signals between 3.3 V logic and 200 V gate-drive circuits in half-bridge drivers.

IC Role / Device Role / Timing Role: High-voltage open-collector interface diode enabling bidirectional voltage translation.

Use Value: Dual-diode structure allows configurable anode/cathode routing; V_RRM = 250 V isolates logic domain from HV domain.

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
BAV23,215	Same die, but in SOT23-3 with different marking (%V4); identical V_RRM, trr, and thermal specs	No functional difference; differs only in traceability code and packaging tape format	Select when sourcing consistency with legacy BAV23 design-in or specific tape-and-reel requirements
MMBD2331LT1G	V_RRM = 200 V (lower), trr = 50 ns (same), C_d = 2.5 pF (slightly higher), I_F = 200 mA (higher)	Better forward current handling but reduced reverse margin; not suitable for 200 V+ systems needing headroom	Prefer for cost-sensitive 100–150 V applications where higher I_F justifies lower V_RRM

Compared with BAV23S,235, BAV23,215 offers identical electrical and thermal behavior with alternate logistics coding, while MMBD2331LT1G trades 50 V reverse margin for +75 mA forward capacity - making it viable only where system voltage stays ≤175 V.

FAQ

What is the maximum junction temperature for continuous operation?

The BAV23S,235 has a rated maximum junction temperature (T_j) of 150 °C. Operation at this limit requires strict adherence to derating curves: total power dissipation must be reduced linearly above T_amb = 25 °C, reaching zero at T_amb = 125 °C for double-diode loading per Figure 5.

Can pin 3 be used as both cathode and anode simultaneously in a circuit?

Yes - pin 3 is internally bonded to both K1 (cathode of diode 1) and A2 (anode of diode 2), enabling simultaneous use in configurations such as series-connected diodes (A1→K1/A2→K2) or common-node clamps. This dual-role terminal is electrically verified and specified in Table 2 of the datasheet.

Is the BAV23S,235 qualified for automotive applications?

No - the BAV23S,235 is explicitly marked as non-automotive qualified in the revision history (Section 14). Nexperia provides automotive-grade alternatives under the -Q suffix (e.g., BAV23S-Q), which undergo AEC-Q101 stress testing and include extended temperature and reliability validation.

How does thermal resistance change when both diodes conduct simultaneously?

When both diodes are loaded, total power dissipation remains within the 250 mW limit, but junction-to-ambient thermal resistance increases due to shared thermal path. Derating curves in Figure 5 show that maximum allowable I_F drops from 125 mA (single diode) to 110 mA (double diode) at T_amb = 25 °C, reflecting cumulative self-heating effects.
