Product details
Overview
BZD27B6V2P-HE3_A18 from Vishay Semiconductors is a surface-mount, AEC-Q101-qualified Zener diode with nominal breakdown voltage of 6.2 V, ±2 % tolerance, 100 mA test current, and 150 W peak surge power rating (10/1000 μs). It operates as a precision voltage reference and transient voltage suppressor in automotive power rail protection circuits.
For engineers reviewing the BZD27B6V2P-HE3_A18 datasheet, BZD27B6V2P-HE3_A18 pinout, BZD27B6V2P-HE3_A18 application, or BZD27B6V2P-HE3_A18 equivalent, key selection criteria include its 6.2 V zener voltage stability, low dynamic resistance (3 Ω), -0.01 to +0.06 %/°C temperature coefficient, AEC-Q101 qualification, and DO-219AB (SMF) package compatibility.
Technical Context
This unidirectional Zener diode uses silicon planar technology for stable voltage regulation under DC bias and clamping during transient overvoltage events. Its design supports both voltage reference and surge suppression roles, with specified clamping voltage of 10.9 V at 13.3 A (10/1000 μs waveform).
The device features low leakage current (≤5 μA at VR = 5 V), excellent long-term stability, and meets JESD201 Class 2 whisker testing and MSL Level 1 reflow requirements (peak 260 °C). Thermal resistance is 30 K/W junction-to-lead and 180 K/W junction-to-ambient on 3 mm × 3 mm Cu pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.08 V min. / 6.2 V nom. / 6.32 V max. - tight ±2 % tolerance enables accurate voltage reference in feedback loops. |
| Test Current (IZT) | 100 mA - standard operating point for specifying VZ, ensuring stable regulation under typical bias conditions. |
| Dynamic Resistance (ZZ) | 3 Ω max. at IZT - low impedance maintains regulation accuracy against load or line variations. |
| Clamping Voltage (VC) | 10.9 V at IRSM = 13.3 A (10/1000 μs) - defines maximum voltage seen by protected circuit during surge. |
| Peak Surge Power (PRSM) | 150 W - sustains high-energy transients without failure, critical for automotive load-dump immunity. |
| Temperature Coefficient (αVZ) | -0.01 to +0.06 %/°C - near-zero drift minimizes voltage error across -65 °C to +175 °C operating range. |
| Junction Temperature (Tj) | 175 °C max. - supports under-hood automotive environments without derating. |
