Nexperia USA Inc. BAW101,215

Overview

BAW101,215 from Nexperia is a high-voltage double switching diode array in SOT143B package, featuring two electrically isolated diodes with 300 V continuous reverse voltage per diode, 50 ns max reverse recovery time, and 250 mA continuous forward current (single diode). It serves in automotive ignition circuits, telecom line interface protection, and high-speed flyback snubbers.

For engineers reviewing the BAW101,215 datasheet, BAW101,215 pinout, BAW101,215 application, or BAW101,215 equivalent, key selection criteria include reverse voltage rating, reverse recovery speed, thermal resistance (R_{th j-a} = 357 K/W), dual-diode isolation integrity, and SOT143B footprint compatibility in space-constrained HV switching layouts.

Technical Context

The BAW101,215 integrates two planar-processed silicon diodes on separate dice within one SOT143B body, enabling independent high-voltage switching paths without internal coupling. Its construction supports series connection up to 600 V reverse blocking and maintains <2 pF capacitance at 0 V bias for minimal signal distortion.

Designed for operation across −65 °C to +150 °C ambient, it delivers stable 150 nA reverse leakage at 250 V/25 °C and degrades predictably to 50 µA at 250 V/150 °C - critical for under-hood automotive reliability validation.

FAQ

What is the maximum allowable junction temperature for BAW101,215?

The absolute maximum junction temperature (T_j) is 150 °C, as specified in the Limiting Values table. Operation above this temperature risks permanent parametric shift or bond-wire failure. Derating begins at 25 °C ambient, with continuous forward current dropping to 140 mA when both diodes are active and ambient exceeds 70 °C.

Can BAW101,215 be used in series configuration for higher reverse voltage?

Yes - the datasheet explicitly states a 600 V repetitive peak reverse voltage (VRRM) for series connection. This requires matched diodes and balanced voltage sharing via equalizing resistors, especially under temperature gradients. The electrically insulated dice ensure no internal coupling compromises series operation.

Is the SOT143B package lead-free and RoHS compliant?

Yes - Nexperia confirms all SOT143B-packaged devices, including BAW101,215, meet RoHS Directive 2011/65/EU and are manufactured with lead-free terminations. The "215" suffix denotes tape-and-reel packaging compliant with J-STD-020 moisture sensitivity level 1 (unlimited floor life at ≤30 °C/60% RH).

How does reverse leakage change at elevated temperature and voltage?

At VR = 250 V and Tamb = 150 °C, reverse current reaches 50 µA - a 333× increase over the 150 nA value at 25 °C. This is documented in Figure 5 and reflects intrinsic silicon behavior; design margins must account for this exponential rise when operating near thermal limits.
