Product details
Overview
BAS28,215 from Nexperia is a high-speed double diode in SOT143B package, comprising two isolated silicon planar switching diodes. It delivers trr ≤ 4 ns reverse recovery time, VRRM = 85 V, and IFRM = 500 mA, with AEC-Q101 qualification for automotive-grade reliability in compact surface-mounted circuits.
For engineers reviewing the BAS28,215 datasheet, BAS28,215 pinout, BAS28,215 application, or BAS28,215 equivalent, this dual diode supports high-frequency signal routing, clamping, and polarity protection where low capacitance (Cd = 1.5 pF), fast switching, and thermal robustness (Tj = 150 °C) are critical.
Technical Context
The BAS28,215 integrates two electrically independent high-speed switching diodes on a single die, fabricated using planar technology to ensure consistent trr ≤ 4 ns under IF = 10 mA / IR = 10 mA test conditions. Its isolation enables flexible configuration in dual-path signal conditioning or redundancy-critical nodes.
Thermal performance is defined by Rth(j-a) = 500 K/W (FR4, single-sided copper) and Rth(j-sp) = 360 K/W, supporting stable operation up to 150 °C junction temperature. Reverse leakage remains ≤ 1 µA at VR = 75 V and 25 °C, rising to 50 µA at 150 °C - a key constraint for high-temperature automotive sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Recovery Time (trr) | 4 ns max - enables reliable operation above 100 MHz in RF detector and pulse shaping circuits. |
| Repetitive Peak Reverse Voltage (VRRM) | 85 V - supports use in 48 V automotive power domains with margin against transients. |
| Repetitive Peak Forward Current (IFRM) | 500 mA - sufficient for dual-channel ESD clamp or logic-level signal steering without derating. |
| Diode Capacitance (Cd) | 1.5 pF at VR = 0 V, 1 MHz - minimizes signal distortion in high-speed data line protection. |
| Forward Voltage (VF) | 1.25 V max at IF = 150 mA - ensures low conduction loss in active rectification or level-shifting paths. |
| Junction Temperature (Tj) | 150 °C max - validated for under-hood automotive modules per AEC-Q101 stress testing. |
Pinout & Package
SOT143B plastic surface-mount package: 4-lead, 1.9 mm pitch, 2.9 mm × 1.3 mm × 1.0 mm body, optimized for reflow soldering with defined footprint per Figure 9.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (cathode of diode 1) | Reference terminal for first diode's reverse-biased path; connects to ground or lower-potential node in clamping. |
| 2 | K2 (cathode of diode 2) | Independent cathode for second diode; allows separate biasing or dual-direction transient suppression. |
| 3 | A2 (anode of diode 2) | Input terminal for diode 2; used in series-switching or OR-ing configurations with diode 1. |
| 4 | A1 (anode of diode 1) | Input terminal for diode 1; enables parallel or complementary routing with A2/K2 for differential signal handling. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control units and ADAS sensor interfaces. |
| trr ≤ 4 ns | Enables clean edge transitions in 100+ Mbps digital signal lines without ringing or timing skew. |
| VRRM = 85 V | Provides 15 V headroom above 48 V nominal vehicle systems, accommodating load-dump spikes. |
| Cd = 1.5 pF | Preserves signal integrity in USB 2.0, CAN FD, and LVDS receiver protection networks. |
| IFRM = 500 mA | Supports dual-diode current sharing in redundant power path designs without external current limiting. |
Applications
| Automotive Sensor Signal Conditioning | High-Speed Data Line Clamping |
|---|---|
Use Scenario: Protecting analog outputs of wheel speed or crankshaft position sensors from ESD and inductive kickback in 12 V/48 V hybrid vehicles. IC Role / Device Role / Timing Role: Dual-diode clamping network with independent cathodes tied to separate reference rails for bidirectional overvoltage suppression. Use Value: Prevents sensor output saturation during 8 kV contact ESD events while maintaining <1 ns propagation delay due to low Cd and trr. |
Use Scenario: Shielding USB 2.0 D+/D− lines from system-level transients in infotainment head units. IC Role / Device Role / Timing Role: Two discrete clamping diodes placed in series with each data line, leveraging isolated anodes/cathodes for precise voltage threshold control. Use Value: Limits line voltage to ±0.7 V beyond VDD without distorting 480 Mbps eye diagrams, enabled by 1.5 pF capacitance and sub-4 ns recovery. |
| Dual-Channel Logic-Level Translation | Redundant Power Path OR-ing |
Use Scenario: Level-shifting between 3.3 V microcontroller GPIOs and 5 V peripheral buses in telematics modules. IC Role / Device Role / Timing Role: Back-to-back diode configuration using A1/K1 and A2/K2 to enable bidirectional voltage translation with minimal forward drop. Use Value: Achieves <10 ns transition delay across 0–3.3 V and 0–5 V thresholds, avoiding latch-up risk inherent in MOSFET-based translators. |
Use Scenario: Combining outputs from two independent 5 V DC-DC converters in safety-critical domain controllers. IC Role / Device Role / Timing Role: Anode-connected diodes (A1/A2 to sources, K1/K2 to common rail) providing passive OR-ing with automatic fault isolation. Use Value: Delivers 500 mA total shared current capacity with <1.25 V forward drop at full load, eliminating need for active ideal diode ICs. |
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 |
|---|---|---|---|
| ON Semiconductor NSR20F40NXT5G | trr = 3.5 ns (slightly faster), VRRM = 40 V (lower), SOD-323 package (smaller, 2-pin) | Limited to ≤24 V systems; unsuitable for 48 V automotive transients due to lower VRRM. | Select only when board space is constrained and voltage requirements are ≤36 V. |
| Diodes Inc. BAV99W-7-F | trr = 4 ns (same), VRRM = 70 V (5 V lower), SOT-363 package (6-pin, shared cathode) | Shared cathode prevents independent biasing; not suitable for dual-rail clamping or OR-ing. | Prefer BAS28,215 when cathode isolation is required for asymmetric reference schemes. |
Compared with NSR20F40NXT5G and BAV99W-7-F, the BAS28,215 uniquely combines 85 V VRRM, fully isolated cathodes/anodes, and AEC-Q101 qualification - making it the only option qualified for dual-diode roles in 48 V automotive power domains requiring independent terminal control.

FAQ
Is BAS28,215 suitable for 48 V automotive power rail protection?
Yes. With VRRM = 85 V and AEC-Q101 qualification, the BAS28,215 withstands load-dump transients up to ISO 7637-2 Pulse 5a (110 V peak) when used with appropriate series impedance. Its 150 °C Tj rating supports under-hood deployment without derating in ambient temperatures up to 125 °C.
Can BAS28,215 be used as a dual-channel ESD protector for USB 2.0 lines?
Yes. Its 1.5 pF diode capacitance and 4 ns trr preserve signal integrity up to 480 Mbps, and its dual-isolated structure allows independent clamping of D+ and D− to separate VBUS and GND rails - meeting IEC 61000-4-2 Level 4 (8 kV contact) requirements when laid out per Nexperia's layout guidelines.
What is the maximum continuous forward current per diode in BAS28,215?
The maximum continuous forward current per diode is 215 mA under standard FR4 PCB mounting (single-sided copper, standard footprint), as specified in Table 1. At higher ambient temperatures, derating applies: Fig. 5 shows linear reduction to zero at 150 °C ambient, with 100 mA allowable at 100 °C ambient.
Does BAS28,215 have matched characteristics between its two diodes?
No. The datasheet does not specify matching - parameters like VF, trr, and IR are given as absolute maximums or typicals for individual diodes, with no tolerance correlation stated between diode 1 and diode 2. For matched-pair applications (e.g., precision rectifiers), discrete single-diode variants with binning data should be selected instead.
