Product details
Overview
BZD27B110P-E3-18 from Vishay Semiconductors is a silicon planar Zener diode optimized for overvoltage protection and precision voltage regulation in high-reliability power rails, with a nominal Zener voltage of 110 V, ±2 % tolerance at 5 mA test current, 145 V clamping voltage at 1 A surge, and 150 W non-repetitive peak surge power rating per 10/1000 μs waveform.
For engineers reviewing the BZD27B110P-E3-18 datasheet, BZD27B110P-E3-18 pinout, BZD27B110P-E3-18 application, or BZD27B110P-E3-18 equivalent, this device serves as a unidirectional, single-element transient voltage suppressor and reference element in automotive power management, industrial DC bus monitoring, and telecom surge protection circuits where stable 110 V regulation and robust 1 kV-class ESD immunity are required.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain a stable reference voltage across its terminals under regulated conditions, while switching to low-impedance clamping during transient overvoltage events. Its design integrates low leakage current (<1 μA at 91 V), tight ±2 % VZ tolerance, and a positive temperature coefficient (+0.09 to +0.13 %/°C) to ensure predictable drift behavior across -65 °C to +175 °C operating range.
The device uses a silicon planar junction structure housed in an SMF (DO-219AB) surface-mount package rated MSL level 1, supporting wave and reflow soldering up to 260 °C peak. It meets AEC-Q101 qualification for automotive use when ordered with -HE3 suffix, though BZD27B110P-E3-18 is RoHS-compliant commercial-grade with JESD201 Class 2 whisker resistance and >8 kV HBM ESD rating.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110A | TVS diode with 110 V standoff, 171 V max clamping at 1 A, 600 W peak power - higher surge capacity but looser voltage tolerance (±5 %) | Better suited for primary surge suppression; less precise for voltage reference use | Select when peak surge energy absorption is prioritized over regulation accuracy |
| BZX84-C110 | SOT-23 Zener with 110 V nominal, ±5 % tolerance, 300 mW power - smaller package, lower surge rating (40 W), no AEC-Q101 option | Limited to low-energy signal-line protection; unsuitable for DC bus clamping | Select only for space-constrained, low-power reference applications where 150 W surge capability is unnecessary |
Compared with SMBJ110A and BZX84-C110, BZD27B110P-E3-18 uniquely balances ±2 % regulation precision, 150 W surge handling, and AEC-Q101-ready construction in a thermally efficient DO-219AB package-making it optimal for automotive and industrial power rail protection where both accuracy and ruggedness are mandatory.

FAQ
What is the Zener voltage tolerance of BZD27B110P-E3-18?
The BZD27B110P-E3-18 has a Zener voltage tolerance of ±2 %, with a specified range of 107.8 V to 112.2 V at 5 mA test current. This tight tolerance ensures consistent voltage regulation performance across production lots and supports precision feedback loop design in power converters without requiring calibration. The value is measured under standard conditions (Tamb = 25 °C) and confirmed in Vishay's official datasheet revision 2.1.
Does BZD27B110P-E3-18 meet AEC-Q101 qualification?
No, BZD27B110P-E3-18 is the commercial-grade RoHS-compliant variant. AEC-Q101 qualification applies only to parts ordered with the -HE3 suffix (e.g., BZD27B110P-HE3_A18). The -E3-18 version shares identical electrical and thermal specifications but lacks formal automotive qualification documentation and stress-test reporting. For automotive applications, specify the -HE3 variant to ensure full AEC-Q101 compliance.
What is the maximum clamping voltage of BZD27B110P-E3-18 during a surge event?
The maximum clamping voltage (VC) of BZD27B110P-E3-18 is 145 V at 1 A peak surge current with a 10/1000 μs waveform. This value is measured per IEC 61000-4-5 and defines the upper voltage limit imposed on protected circuits during transient events. It reflects the device's ability to enter low-impedance conduction rapidly while maintaining thermal integrity within its 150 W PRSM rating.
Can BZD27B110P-E3-18 be used in reflow soldering processes?
Yes, BZD27B110P-E3-18 is fully compatible with standard lead-free reflow soldering processes, with a maximum peak temperature of 260 °C. Its SMF (DO-219AB) package meets J-STD-020 MSL level 1 requirements, meaning it can be stored indefinitely at ambient conditions without baking prior to assembly. The device also supports wave soldering and passes JESD201 Class 2 whisker testing.
What is the thermal resistance from junction to ambient for BZD27B110P-E3-18?
The junction-to-ambient thermal resistance (RthJA) of BZD27B110P-E3-18 is 180 K/W when mounted on an epoxy-glass PCB with 3 mm × 3 mm copper pads ≥40 μm thick. This value determines steady-state power derating: at 30 °C ambient, the device supports 800 mW continuous dissipation, dropping to zero at 105 °C board temperature. RthJA is validated per JEDEC test conditions and directly impacts thermal design margin in high-density layouts.
