Product details
Overview
BZD27B100P-HE3_A08 from Vishay Semiconductors is a surface-mount, AEC-Q101 qualified Zener diode with nominal breakdown voltage of 100 V, ±2 % tolerance, 5 mA test current, and 134 V clamping voltage at 1 A surge current. It delivers 150 W non-repetitive peak surge power (10/1000 μs), operates from −65 °C to +175 °C, and is used for overvoltage protection in automotive power rails and industrial DC bus lines.
For engineers reviewing the BZD27B100P-HE3_A08 datasheet, BZD27B100P-HE3_A08 pinout, BZD27B100P-HE3_A08 application, or BZD27B100P-HE3_A08 equivalent, key selection criteria include Zener voltage accuracy, surge power rating, temperature coefficient (+0.09 to +0.13 %/°C), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This unidirectional Zener diode functions as a precision voltage reference and transient voltage suppressor in DC circuits. Its silicon planar construction ensures low leakage current (<5 μA at VR = 82 V), stable dynamic resistance (75 Ω at IZT = 5 mA), and tight voltage tolerance across temperature.
The device uses the SMF (DO-219AB) package-low-profile, MSL level 1 compliant, wave and reflow solderable-with thermal resistance RthJA = 180 K/W on 3 mm × 3 mm Cu pads and RthJL = 30 K/W, enabling robust thermal performance in high-power pulse conditions.

FAQ
What is the Zener voltage tolerance of BZD27B100P-HE3_A08?
The BZD27B100P-HE3_A08 has a Zener voltage range of 98.0 V to 102.0 V at 5 mA test current, corresponding to ±2 % tolerance around the nominal 100 V rating. This tight tolerance is specified per the BZD27B Series datasheet (Rev. 2.1, Dec. 2022) and applies across the full operating temperature range of −65 °C to +175 °C.
Is BZD27B100P-HE3_A08 suitable for automotive applications?
Yes, BZD27B100P-HE3_A08 is AEC-Q101 qualified and explicitly rated for automotive use. Its construction meets JESD 201 Class 2 whisker testing, HBM ESD >8 kV, and operates reliably from −65 °C to +175 °C-making it appropriate for engine control, body electronics, and ADAS subsystems per ISO 16750-2 requirements.
What is the maximum clamping voltage of BZD27B100P-HE3_A08 during surge events?
The BZD27B100P-HE3_A08 clamps to 134 V at 1 A peak reverse current under the 10/1000 μs waveform condition, as confirmed in the "Electrical Characteristics" table on page 3 of the Vishay datasheet (Document No. 85921). This value defines its overvoltage limiting behavior during standardized surge tests.
Which package does BZD27B100P-HE3_A08 use, and what are its key mechanical features?
BZD27B100P-HE3_A08 uses the SMF (DO-219AB) package: a low-profile surface-mount outline measuring 2.7 mm × 3.5 mm × 0.85 mm, with MSL level 1 moisture sensitivity and compatibility with standard reflow profiles up to 260 °C peak temperature. Its cathode is marked by a visible band on the top surface.
How does the temperature coefficient affect BZD27B100P-HE3_A08's performance in wide-temperature environments?
The BZD27B100P-HE3_A08 exhibits a positive temperature coefficient of +0.09 to +0.13 %/°C, meaning its Zener voltage increases predictably with junction temperature. This allows designers to compensate for thermal drift in high-temperature applications such as under-hood automotive electronics or industrial motor drives where ambient exceeds 100 °C.
