Product details
Overview
BAV23,215 from Nexperia is a dual high-voltage switching diode in SOT143B package, configured as two independent silicon PN junction diodes with isolated anodes and cathodes. It delivers 250 V repetitive peak reverse voltage (VRRM), ≤50 ns reverse recovery time (trr), and ≤2 pF capacitance per diode - enabling reliable high-speed switching in flyback snubbers, relay drivers, and HV logic interface circuits.
For engineers reviewing the BAV23,215 datasheet, BAV23,215 pinout, BAV23,215 application, or BAV23,215 equivalent, key selection criteria include verified dual-diode isolation, sub-50 ns trr at IF = 10 mA/IR = 10 mA, 200 V DC blocking capability, thermal resistance of 500 K/W (junction-to-ambient), and compatibility with standard FR4 reflow soldering footprints.
Technical Context
The BAV23,215 integrates two electrically isolated high-voltage switching diodes in a single 4-pin SOT143B package, with separate anode (A1, A2) and cathode (K1, K2) terminals. Its fast recovery behavior is characterized under defined test conditions: IF = 10 mA, IR = 10 mA, IR(meas) = 1 mA, RL = 100 Ω, Tamb = 25 °C.
Thermal performance is specified for mounting on FR4 PCB with single-sided copper and standard footprint: Rth(j-a) = 500 K/W and Rth(j-sp) = 360 K/W. Absolute maximum ratings include VRRM = 250 V, IFRM = 625 mA, and Tj(max) = 150 °C - supporting operation in industrial power supply and signal routing applications up to 85 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 250 V - supports repetitive blocking of high-voltage transients in DC-DC converters and relay coil suppression |
| trr | ≤50 ns - enables clean switching at >1 MHz in high-frequency snubber and clamp circuits |
| Cd | ≤2 pF at VR = 0 V, f = 1 MHz - minimizes capacitive loading in high-impedance timing and sampling nodes |
| IR | ≤100 nA at VR = 200 V, 25 °C - ensures low leakage in high-impedance bias networks and HV hold-off paths |
| VF | 1.25 V max at IF = 200 mA - limits forward conduction loss in moderate-current switching paths |
| Ptot | 250 mW at Tamb ≤ 25 °C - defines thermal derating envelope for continuous operation on standard FR4 PCB |
Pinout & Package
SOT143B: 4-lead surface-mount plastic package, 2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch, optimized for automated placement and reflow soldering on FR4 PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 | Cathode of diode 1 - connects to return path for first high-voltage switching leg |
| 2 | K2 | Cathode of diode 2 - provides independent return for second switching channel |
| 3 | A2 | Anode of diode 2 - accepts high-voltage input for second isolated switching function |
| 4 | A1 | Anode of diode 1 - accepts high-voltage input for primary switching leg with full electrical isolation from A2/K2 |
Key Features
| Feature | Design Value |
|---|---|
| High-speed switching | trr ≤ 50 ns ensures minimal switching loss and reduced EMI in >1 MHz power control loops |
| Dual-diode isolation | Independent A1/K1 and A2/K2 terminals enable fully separated high-voltage signal paths without internal coupling |
| Low leakage current | IR ≤ 100 nA at 200 V supports stable biasing in precision HV monitoring and sample-hold circuits |
| Small SMD footprint | SOT143B package saves board space versus discrete SO-8 or TO-236 alternatives while maintaining 250 V rating |

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 |
|---|---|---|---|
| BAV21,215 | VRRM = 200 V (vs. 250 V); trr ≤ 50 ns; same SOT143B package and pinout | Limited to ≤200 V systems; unsuitable for 250 V-rated snubbers or relay drivers | Select when 200 V rating suffices and cost optimization is prioritized over margin |
| MMBD2837LT1G | VRRM = 200 V; trr ≤ 4 ns (faster); Cd = 1.5 pF; SOT-23-3 package with common cathode | Single-package dual-cathode configuration reduces layout flexibility; not pin-compatible | Choose only when ultra-fast recovery (<5 ns) is required and shared cathode architecture fits the design |
Compared with BAV21,215, the BAV23,215 offers higher voltage margin (250 V vs. 200 V) for robustness in fluctuating HV rails; compared with MMBD2837LT1G, it trades speed for full terminal isolation and pin-compatibility - critical for dual-channel protection where anode separation is mandatory.

FAQ
Is BAV23,215 automotive-qualified?
No. The BAV23,215 is explicitly marked as non-automotive qualified in the 2023 datasheet revision. It lacks AEC-Q101 qualification and is intended for industrial, commercial, and general-purpose applications. For automotive use, Nexperia recommends its -Q qualified alternatives such as the BAV23W-Q series, which undergo extended reliability testing including temperature cycling and humidity bias HAST.
What is the thermal derating behavior above 25 °C ambient?
Per Figure 5 in the datasheet, the BAV23,215's forward current rating decreases linearly with ambient temperature: at 85 °C ambient, the maximum continuous forward current drops to ~150 mA per diode (single-loaded), and to ~100 mA when both diodes are simultaneously active. Derating follows a fixed slope of −1.25 mA/°C beyond 25 °C for double-diode loading.
Can BAV23,215 be used in reverse-series configuration for higher voltage blocking?
No. The BAV23,215 contains two independent diodes with no internal series connection; its absolute maximum reverse voltage rating (VRRM = 250 V) applies per diode. Connecting A1–K2 or other cross-terminal configurations violates the device's pinning and may cause premature breakdown due to unequal voltage sharing and uncontrolled junction heating.
Does the marking code %L3 indicate RoHS compliance?
Yes. The "%L3" top-side marking on BAV23,215 devices conforms to Nexperia's standardized RoHS-compliant coding system, where "L" denotes lead-free termination and halogen-free packaging. All BAV23,215 units shipped since 2010 meet EU RoHS Directive 2011/65/EU and JEDEC J-STD-609A Class 1 requirements.
