Product details
Overview
BAS21AVD-Q from Nexperia is a triple high-voltage switching diode array in SOT457 (TSOP6) package, designed for automotive and communication circuits requiring fast reverse recovery (trr ≤ 50 ns), 250 V repetitive peak reverse voltage (VRRM), and low capacitance (Cd ≤ 5 pF). It integrates three independent diodes with isolated anodes and cathodes for discrete high-side switching in compact SMD layouts.
For engineers reviewing the BAS21AVD-Q datasheet, BAS21AVD-Q pinout, BAS21AVD-Q application, or BAS21AVD-Q equivalent, key selection criteria include verified AEC-Q101 qualification, per-diode 200 mA pulsed forward current rating, 16 ns typical reverse recovery time at 30 mA, and thermal resistance of 425 K/W junction-to-solder-point under standard FR4 mounting.
Technical Context
This triple diode device implements three independent PN-junction switching elements in a single TSOP6 package, each with fully isolated terminals (A1/K1, A2/K2, A3/K3) enabling flexible series/parallel or multi-rail configurations. Its design targets high-voltage transient suppression and signal routing where low charge storage and minimal capacitive loading are critical.
The device operates within a −65 °C to 150 °C ambient range, with junction temperature limited to 150 °C and thermal resistance from junction to solder point specified at 140 K/W. Reverse leakage remains ≤100 nA at VR = 200 V and 25 °C, rising to ≤100 µA at 150 °C - a behavior confirmed by Figure 3 in the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 250 V - supports repetitive blocking of transients up to this voltage without avalanche breakdown |
| trr (typ) | 16 ns - enables clean switching in >10 MHz pulse applications with minimal tail current |
| Cd (typ) | 0.6 pF - reduces capacitive crosstalk and signal distortion in RF-coupled or high-speed logic interfaces |
| IFRM | 1 A - allows sustained 1 A peak forward current per diode under 25% duty cycle conditions |
| IR @ 200 V | 25 nA (typ) - ensures negligible leakage-induced offset in precision high-impedance bias networks |
| Rth(j-sp) | 140 K/W - defines thermal path efficiency from die to PCB solder joint under recommended pad layout |
| Ptot | 295 mW - maximum total power dissipation at Tamb ≤ 25 °C with standard FR4 footprint |
Pinout & Package
Package: SOT457 (TSOP6), 6-lead surface-mount plastic package with 0.65 mm lead pitch, 2.7 mm × 1.7 mm body size, and exposed cathode thermal pad geometry per Figure 8 and Figure 9.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (Diode 1) | Input terminal for first diode; connects to high-side switching node or signal source |

| 3 | Anode (Diode 3) | Third isolated anode; supports triple-output protection or multi-channel isolation |
| 4 | Cathode (Diode 3) | Return path for third diode; shares no internal connection with other cathodes |
| 5 | Cathode (Diode 2) | Independent return for second diode; allows separate grounding or rail referencing |
| 6 | Cathode (Diode 1) | Dedicated return for first diode; enables true 3× independent diode operation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including HTOL, TC, HAST, and ESD testing per JESD47 |
| Triple isolated diodes | No shared anodes or cathodes - enables independent routing, biasing, and failure containment |
| Low trr dispersion | 16 ns typical / 50 ns max at IF = IR = 30 mA - ensures consistent timing across production lots |
| FR4-optimized thermal design | 425 K/W Rth(j-a) on standard single-sided tin-plated FR4 - simplifies thermal management in cost-sensitive designs |
| Small outline footprint | TSOP6 package occupies < 4.6 mm² PCB area - saves space vs. three discrete SOD-323 devices |

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 |
|---|---|---|---|
| ON Semiconductor NSR20F20NXT5G | Single diode, 200 V VRRM, 35 ns trr, SOD-523 package | Lacks triple-diode integration; requires three devices for equivalent channel count | Select when board space permits discrete placement and thermal separation is preferred |
| Diodes Incorporated BAV21WQ-7-F | Triple diode in SOT-363, 250 V VRRM, 50 ns trr, AEC-Q101 qualified | Higher Cd (8 pF typ); larger 2.2 mm × 2.4 mm footprint than TSOP6 | Choose when existing layout uses SOT-363 land pattern and higher capacitance is acceptable |
Compared with NSR20F20NXT5G and BAV21WQ-7-F, BAS21AVD-Q delivers superior space efficiency (4.6 mm² vs ≥12 mm²), lower capacitance (0.6 pF vs 8 pF), and tighter trr consistency (16 ns typ), making it optimal for dense automotive and high-speed communication modules.

FAQ
What is the maximum pulsed forward current per diode in BAS21AVD-Q?
The maximum pulsed forward current per diode is 200 mA under conditions of tp ≤ 300 µs and duty cycle δ ≤ 0.02 on a standard FR4 PCB. This rating is validated per Table 1 and Table 5 in the datasheet and reflects safe operation without thermal runaway during short-duration switching events.
Is BAS21AVD-Q suitable for bidirectional transient voltage suppression?
Yes - each diode supports reverse blocking up to 250 V (VRRM) and forward conduction up to 200 mA, enabling use in bidirectional TVS configurations. Its 16 ns typical trr and low leakage ensure effective clamping of both positive and negative transients without oscillation or latch-up.
How does the TSOP6 package affect thermal performance compared to SOD-323?
The TSOP6 package provides 425 K/W junction-to-ambient thermal resistance on standard FR4, significantly better than typical SOD-323 (≈600 K/W), due to its larger copper exposure and optimized leadframe geometry. This allows higher sustained power dissipation without derating in space-constrained automotive modules.
Can BAS21AVD-Q replace three individual BAS21LT1G diodes in a design?
Yes - BAS21AVD-Q integrates three functionally identical high-voltage switching diodes with matching specifications (VRRM = 250 V, trr ≤ 50 ns, Cd ≤ 5 pF) in one TSOP6 package. Pin mapping is fully independent, enabling direct substitution when board layout accommodates the 6-pin footprint and thermal pad requirements.
