Product details
Overview
BAS21AVD from Nexperia is a triple high-voltage switching diode in SOT457 (TSOP6) package, designed for fast-switching applications requiring ≤50 ns reverse recovery time, 250 V repetitive peak reverse voltage (VRRM), and AEC-Q101 qualification for automotive use. It integrates three independent diodes with anode-cathode pairing per channel and supports pulsed forward currents up to 200 mA per diode.
For engineers reviewing the BAS21AVD datasheet, BAS21AVD pinout, BAS21AVD application, or BAS21AVD equivalent, key selection criteria include its triple-diode topology, low 5 pF capacitance at 0 V, 16 ns typical trr, AEC-Q101 qualification, and thermal resistance of 425 K/W junction-to-solder-point - critical for compact automotive and telecom power rail switching designs.
Technical Context
The BAS21AVD implements three monolithically integrated silicon switching diodes in a single TSOP6 package, each with independently accessible anode and cathode terminals. Its design targets high-speed voltage clamping and signal routing where low stored charge and minimal reverse recovery tail current are essential.
It operates with a maximum junction temperature of 150 °C and exhibits stable reverse leakage (≤100 nA at 200 V, 25 °C) and forward voltage (≤1.25 V at 200 mA, 25 °C). Thermal performance is defined relative to FR4 PCB mounting with standardized solder pad geometry per IEC 60134 limiting values.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 250 V - supports surge-tolerant switching in 24 V/48 V automotive power rails without derating |
| trr (typ) | 16 ns - enables >10 MHz switching frequency in flyback snubbers and signal clamping circuits |
| Cd (max) | 5 pF at 1 MHz, 0 V - minimizes capacitive loading on high-impedance RF or data line interfaces |
| IFRM | 1 A - handles repetitive pulse loads in relay driver or solenoid control outputs |
| IR (max) | 100 nA at VR = 200 V, 25 °C - ensures low standby leakage in battery-backed or always-on systems |
| Rth(j-sp) | 140 K/W - defines thermal path efficiency from junction to cathode solder point under standard PCB layout |
Pinout & Package
Package: SOT457 (TSOP6), 6-pin surface-mount plastic package with 0.65 mm pitch, 3.0 × 1.7 mm footprint, and exposed cathode-side thermal pad geometry optimized for FR4 PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A1 - Anode of Diode 1 | Input node for first diode; connects to high-side switching node or signal source |
| 2 | A2 - Anode of Diode 2 | Independent input for second diode; enables dual-rail or differential clamping |
| 3 | A3 - Anode of Diode 3 | Third independent anode; supports triple-channel protection or redundancy schemes |
| 4 | K3 - Cathode of Diode 3 | Output return for third diode; shares common cathode plane with pins 5 and 6 in layout |
| 5 | K2 - Cathode of Diode 2 | Return path for second diode; electrically isolated but thermally coupled to K3/K1 |
| 6 | K1 - Cathode of Diode 1 | Return for first diode; designated pin 1 index location aligns with cathode-side thermal pad |
Key Features
| Feature | Design Value |
|---|---|
| Triple-diode integration | Three independent high-voltage diodes in one TSOP6 footprint - reduces board area by ~60% vs. discrete SOD-323 solutions |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD - suitable for under-hood ECUs |
| Low trr dispersion | 16 ns typical / 50 ns max - tight distribution enables predictable timing in synchronous rectifier gate drive circuits |
| Thermal optimization | Rth(j-sp) = 140 K/W - enables 295 mW total power dissipation with <10 °C junction rise over ambient on standard FR4 |
| Low IR at high VR | 25 nA typical reverse current at 200 V - preserves signal integrity in high-impedance sensor bias networks |
Applications
| Automotive Power Rail Protection | Telecom Line Interface Clamping |
|---|---|
Use Scenario: Transient suppression on 12 V/24 V battery-fed microcontroller I/O lines in body control modules. IC Role / Device Role / Timing Role: Fast clamping diode array absorbing load-dump spikes and ISO 7637-2 pulses before they reach sensitive logic inputs. Use Value: 250 V VRRM withstands 100 V transients; 16 ns trr limits energy dissipation during sub-microsecond surges. |
Use Scenario: ESD and overvoltage protection on RS-485/RS-422 differential bus lines in base station backhaul equipment. IC Role / Device Role / Timing Role: Bidirectional voltage clamp using paired diodes across differential pairs to limit common-mode excursions. Use Value: 5 pF capacitance avoids signal integrity degradation at 10 Mbps; AEC-Q101 grade ensures field reliability. |
| Industrial Sensor Signal Conditioning | High-Speed Switch-Mode Power Supply Snubbing |
Use Scenario: Bias network protection for precision analog sensors (e.g., RTDs, strain gauges) in PLC analog input modules. IC Role / Device Role / Timing Role: Low-leakage voltage limiter preventing sensor excitation circuit damage from accidental 24 V miswiring. Use Value: 100 nA max IR at 200 V prevents offset drift; triple configuration allows simultaneous protection of V+, V−, and REF lines. |
Use Scenario: RCD snubber network in 100 kHz–500 kHz flyback converters for industrial AC/DC adapters. IC Role / Device Role / Timing Role: High-speed recovery diode in snubber leg to absorb transformer leakage energy without oscillation. Use Value: 50 ns max trr ensures clean turn-off before next switching cycle; 1 A IFRM sustains repeated snubber conduction. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAS21DW,115 | Same triple-diode SOT363 package; VRRM = 250 V but trr = 50 ns max (no typ value specified); Cd = 4 pF max | Smaller footprint (2.1 × 1.25 mm) but higher thermal resistance (Rth(j-a) = 500 K/W); less suitable for sustained 1 A pulsed loads | Select when board space is constrained and thermal margin exceeds 20 °C; verify snubber timing with worst-case trr |
| MMBD2103LT1G | Triple diode in SOT-23-6; VRRM = 200 V; trr = 4 ns typ (faster); Cd = 2 pF max; not AEC-Q101 qualified | Superior speed and capacitance for RF/data line clamping, but lacks automotive qualification and has lower VRRM margin | Prefer for non-automotive high-frequency signal routing; avoid in safety-critical or temperature-cycled environments |
Compared with BAS21AVD, BAS21DW offers smaller size but reduced thermal capability, while MMBD2103LT1G delivers faster switching and lower capacitance but sacrifices automotive qualification and voltage headroom - making BAS21AVD the optimal balance for automotive and industrial power rail protection where reliability and 250 V margin are mandatory.

FAQ
What is the maximum allowable junction temperature for BAS21AVD during continuous operation?
The absolute maximum junction temperature (Tj) for BAS21AVD is 150 °C, as defined in IEC 60134 limiting values. Continuous operation must maintain Tj ≤ 150 °C under worst-case ambient and power dissipation conditions. Derating curves in Figure 5 show that at Tamb = 100 °C, VR must be reduced to ~150 V to stay within thermal limits on standard FR4 PCBs.
Can BAS21AVD be used in parallel configurations to increase current handling?
No - BAS21AVD is not characterized or recommended for parallel operation. Its forward voltage variation (VF = 1.0–1.25 V at 200 mA) and thermal coupling between diodes in the same package create imbalance risks. For higher current, use discrete diodes with matched VF or select a higher-rated single-diode part like PMEG2010CEH.
Is the SOT457 package lead-free and RoHS compliant?
Yes - BAS21AVD is manufactured in a lead-free, RoHS-compliant SOT457 package per Nexperia's product compliance documentation. The device meets JEDEC J-STD-020 moisture sensitivity level (MSL) 1 and supports standard reflow profiles including IPC/JEDEC J-STD-020 Rev. E.
How does the AEC-Q101 qualification impact BAS21AVD's use in non-automotive applications?
AEC-Q101 qualification confirms extended reliability testing (e.g., 1000-hour HTOL, temperature cycling, ESD ≥ 8 kV HBM), which directly benefits industrial and telecom applications requiring long service life and field robustness. It does not restrict usage outside automotive - rather, it provides verified margin for harsh environments.
