The BZD27B13P-HE3_A08 has a zener voltage tolerance of ±2 %, with a nominal value of 13.0 V and specified range of 12.74 V to 13.26 V at 50 mA test current. This tight tolerance is confirmed in the Vishay BZD27B Series datasheet revision 2.1, table on page 2. The BZD27B13P-HE3_A08 achieves this performance using silicon planar Zener technology and is factory-tested to meet this specification under standard conditions.
Is BZD27B13P-HE3_A08 qualified for automotive applications?
Yes, BZD27B13P-HE3_A08 is AEC-Q101 qualified, as indicated by the "-HE3" suffix in its ordering code and explicitly stated in the Vishay datasheet section "FEATURES". It also passes JESD201 Class 2 whisker testing and supports reflow soldering up to 260 °C. The BZD27B13P-HE3_A08 is intended for under-hood and powertrain applications where reliability across -65 °C to +175 °C is required.
What is the maximum clamping voltage of BZD27B13P-HE3_A08 during surge events?
The maximum clamping voltage of BZD27B13P-HE3_A08 is 17.8 V at 7.9 A peak surge current (10/1000 μs waveform), per the "ELECTRICAL CHARACTERISTICS" table on page 3 of the Vishay datasheet. This value defines the upper voltage limit imposed on protected circuits during standardized transients. The BZD27B13P-HE3_A08 maintains this clamping performance while dissipating up to 150 W peak surge power.
Which package does BZD27B13P-HE3_A08 use, and what are its dimensions?
BZD27B13P-HE3_A08 uses the DO-219AB (SMF) package, measuring 2.7 mm × 3.5 mm × 0.85 mm with cathode marking on the top surface. This low-profile SMD outline is documented in the "PACKAGE DIMENSIONS" section (page 5) of the Vishay datasheet. The BZD27B13P-HE3_A08's footprint recommendation specifies 1.3 mm × 1.3 mm pad size and 1.4 mm center-to-center spacing for reliable reflow soldering.
Does BZD27B13P-HE3_A08 have moisture sensitivity level (MSL) rating?
Yes, BZD27B13P-HE3_A08 is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and requires no baking prior to reflow soldering. This is confirmed in the "PACKAGE" table on page 1 of the Vishay datasheet and supports high-throughput manufacturing. The BZD27B13P-HE3_A08's MSL Level 1 status is enabled by its UL 94 V-0 molding compound and hermetic sealing process.
