It delivers stable voltage regulation and transient overvoltage protection in automotive power rail conditioning circuits.
For engineers reviewing the BZD27C110P-HE3-18 datasheet, BZD27C110P-HE3-18 pinout, BZD27C110P-HE3-18 application, or BZD27C110P-HE3-18 equivalent, key selection criteria include its 104–116 V zener voltage range, 91 V clamping voltage at 5 A, ±0.13 %/°C temperature coefficient, and MSL level 1 reflow compatibility up to 260 °C.
Technical Context
This device operates as a precision voltage reference and transient voltage suppressor in unidirectional configuration. Its silicon planar construction ensures low leakage current (<1 μA at VR), excellent long-term stability, and compliance with JESD201 class 2 whisker testing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110A | TVS diode (not Zener-regulated); higher clamping ratio (187 V @ 5 A), bidirectional capability | Designed for general-purpose surge suppression, not precision voltage reference use | Select when primary need is high-energy transient absorption rather than regulated voltage stabilization |
| BZD27C110P-E3-18 | Same zener family, identical electrical specs, but commercial-grade (non-AEC-Q101 qualified) | Lacks automotive qualification; unsuitable for safety-critical or under-hood deployments | Choose for cost-sensitive industrial or consumer applications where AEC-Q101 is not mandated |
Compared with BZD27C110P-HE3-18, SMBJ110A offers superior surge handling but lacks tight zener tolerance and temperature stability; BZD27C110P-E3-18 matches all electrical parameters but omits automotive reliability validation-making the HE3 variant essential for automotive OEM designs requiring traceable qualification evidence.

FAQ
What is the zener voltage tolerance of BZD27C110P-HE3-18?
The BZD27C110P-HE3-18 has a zener voltage range of 104 V to 116 V at 5 mA test current, corresponding to ±5.5 % tolerance around the nominal 110 V value. This tolerance is guaranteed across the full operating temperature range of -65 °C to +175 °C and is verified per AEC-Q101 stress testing protocols.
Does BZD27C110P-HE3-18 support lead-free reflow soldering?
Yes, BZD27C110P-HE3-18 is fully compatible with lead-free reflow processes, with a maximum peak temperature rating of 260 °C per J-STD-020. It is classified as MSL level 1, meaning it can be stored indefinitely at ambient conditions without baking prior to assembly.
How does the clamping voltage of BZD27C110P-HE3-18 compare to its zener voltage?
The clamping voltage (VC) of BZD27C110P-HE3-18 is 150 V at 5 A (10/1000 μs waveform), which is ~36 % higher than its nominal zener voltage of 110 V. This differential reflects the device's ability to absorb high-energy transients while maintaining predictable voltage limiting behavior under surge conditions.
Is BZD27C110P-HE3-18 suitable for bidirectional transient protection?
No, BZD27C110P-HE3-18 is a unidirectional Zener diode and is not rated for reverse conduction beyond its specified zener breakdown. For bidirectional protection, a paired device or dedicated bidirectional TVS like SMBJ110CA would be required instead of BZD27C110P-HE3-18.
What is the maximum continuous power dissipation for BZD27C110P-HE3-18 at 30 °C ambient?
At TA = 30 °C, the BZD27C110P-HE3-18 has a maximum continuous power dissipation (Ptot) of 800 mW. This value decreases linearly with rising ambient temperature, reaching zero at 175 °C junction temperature, based on its RthJA = 180 K/W rating on standard 3 mm × 3 mm Cu pads.
