Product details
Overview
BAS21VD from Nexperia is a triple high-voltage switching diode array in a SOT457 (TSOP6) package, designed for fast-switching, low-capacitance, high-reliability applications requiring up to 200 V reverse voltage, ≤50 ns reverse recovery time, and ≤5 pF junction capacitance. It serves as a compact, AEC-Q101-qualified solution for high-voltage signal routing and protection in automotive and telecom front-end circuits.
For engineers reviewing the BAS21VD datasheet, BAS21VD pinout, BAS21VD application, or BAS21VD equivalent, key selection criteria include verified trr ≤ 50 ns at IF = 30 mA, VR = 200 V reverse blocking capability, Cd ≤ 5 pF at f = 1 MHz, and triple-diode configuration with independent anode/cathode terminals per diode - all validated for surface-mounted automotive-grade deployment.
Technical Context
The BAS21VD integrates three independent silicon switching diodes in a single TSOP6 package, each rated for repetitive peak reverse voltage (VRRM) of 250 V and forward surge current (IFSM) up to 16 A (tp = 10 µs). Its design targets high-speed transient suppression and signal path switching where low stored charge and minimal capacitive loading are critical.
Thermal performance is defined by Rth(j-a) = 500 K/W (FR4, standard footprint) and Rth(j-sp) = 140 K/W, supporting operation up to Tj = 150 °C. The device meets AEC-Q101 stress test requirements for discrete semiconductors, confirming suitability for under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 250 V - Maximum repetitive reverse voltage per diode without breakdown |
| trr | 16–50 ns - Verified reverse recovery time under IF = 30 mA / IR = 30 mA test conditions |
| Cd | 0.6–5 pF - Junction capacitance at f = 1 MHz and VR = 0 V, enabling RF-friendly signal routing |
| IFRM | 1 A - Repetitive peak forward current at δ ≤ 25 % duty cycle, supporting pulsed power handling |
| VF | 1.25 V max at IF = 200 mA - Low forward drop ensures minimal conduction loss in switching paths |
| IR | 100 nA typ at VR = 200 V / Tamb = 25 °C - Ultra-low leakage preserves signal integrity in high-impedance nodes |
Pinout & Package
Package: SOT457 (TSOP6), 6-lead surface-mount plastic package with 1.3 mm height, 2.5 mm width, and 3.0 mm length; optimized for automated reflow assembly on FR4 PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 | Cathode of diode 1 - referenced ground node for first switching path |
| 2 | K2 | Cathode of diode 2 - isolated cathode terminal enabling independent bias control |
| 3 | K3 | Cathode of diode 3 - third independent cathode for multi-rail clamping or steering |
| 4 | A3 | Anode of diode 3 - high-side input for third diode path |
| 5 | A2 | Anode of diode 2 - second high-side input, electrically isolated from A1/A3 |
| 6 | A1 | Anode of diode 1 - primary high-side input, positioned opposite K1 for optimal layout symmetry |
Key Features
| Feature | Design Value |
|---|---|
| Triple independent diodes | Three fully isolated PN junctions in one TSOP6 footprint - reduces board area vs. discrete SOD-323 solutions |
| AEC-Q101 qualification | Validated for automotive temperature range (−65 °C to +150 °C) and mechanical stress - enables direct use in ADAS and body control modules |
| Low trr (≤50 ns) | Minimizes switching losses and ringing in 100 kHz–1 MHz DC-DC flyback snubbers and signal clamps |
| Low Cd (≤5 pF) | Preserves bandwidth in RF detector, antenna switch, and high-frequency data line protection circuits |
| High VR (200 V) | Supports 48 V automotive systems and PoE+ (IEEE 802.3at) interface protection without derating |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage switching diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAS21DW,115 | Same triple-diode topology and SOT363 package; trr = 16–50 ns but Cd = 6 pF (vs. 5 pF max); VRRM = 250 V identical | SOT363 has larger pad pitch (0.65 mm vs. TSOP6's 0.5 mm), easing hand-soldering but increasing PCB area | Select when manual rework or legacy footprint compatibility outweighs 1 pF capacitance penalty |
| MBR0520L | Single Schottky diode in SOD-123; VF = 0.33 V (lower), but VRRM = 20 V only and no triple configuration | Not functionally equivalent - lacks multi-diode integration and high-voltage capability | Only suitable for low-voltage (<24 V), low-loss forward conduction; not a replacement for BAS21VD's high-VR switching role |
Compared with BAS21VD, BAS21DW,115 offers identical electrical specs in a more manufacturable package but trades 1 pF higher capacitance; MBR0520L provides lower VF but fails to meet the 200 V VR and triple-diode functional requirements entirely.

FAQ
Is BAS21VD suitable for 48 V automotive battery rail protection?
Yes. With VRRM = 250 V and VR = 200 V, the BAS21VD supports full 48 V system operation including ISO 16750-2 load-dump transients (up to 60 V sustained + 100 V spikes). Its AEC-Q101 qualification confirms reliability under automotive thermal and vibration stress profiles.
Can BAS21VD replace three individual BAS21 diodes in a design?
No. While functionally equivalent per diode, the BAS21VD uses a non-standard pinout (K1/K2/K3/A3/A2/A1) that differs from the SOT23-3 BAS21. Layout redesign and netlist updates are required due to different terminal mapping and shared thermal path in the TSOP6 package.
What is the maximum continuous forward current per diode?
The datasheet specifies IF = 200 mA (pulsed, tp ≤ 300 µs, δ ≤ 0.02) and Ptot = 295 mW at Tamb ≤ 25 °C. Continuous DC current is limited by thermal dissipation; at 25 °C ambient, ~120 mA per diode is sustainable assuming one diode active and standard FR4 mounting.
Does BAS21VD support wave soldering?
Yes. Nexperia provides dedicated wave soldering footprints (Fig. 10) for TSOP6, specifying 1.45 mm solder land width, 0.45 mm resist opening, and preferred transport direction. Peak temperature must stay below 260 °C for ≤5 s to avoid package delamination or bond wire damage.
