Product details
Overview
BZT52HC6V2WFQ from Diodes Incorporated is an AEC-Q101 qualified surface-mount Zener diode in SOD123F package, providing precise 5.8–6.6 V nominal Zener voltage at 5 mA test current, 10 Ω maximum Zener impedance, and ±3.7 mV/°C temperature coefficient. It delivers 375 mW power dissipation on standard FR-4 PCB and supports automotive voltage regulation and ESD protection circuits.
For engineers reviewing the BZT52HC6V2WFQ datasheet, BZT52HC6V2WFQ pinout, BZT52HC6V2WFQ application, or BZT52HC6V2WFQ equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (150 °C/W with 1 cm² cathode pad), reverse leakage (<3 µA at 4 V), junction-to-ambient thermal performance, and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable reference voltage under varying load and temperature conditions. Its low 10 Ω dynamic impedance at 5 mA ensures minimal voltage deviation during transient current changes, while the ±3.7 mV/°C temperature coefficient enables predictable drift compensation in precision bias networks.
The SOD123F package features a flat lead design optimized for high power density and low profile mounting. With 150 °C/W thermal resistance when mounted on 1 cm² copper pad, it supports sustained 830 mW power dissipation-critical for overvoltage clamping in automotive control modules and sensor signal conditioning paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.8–6.6 V at IZT = 5 mA - defines stable regulation range for 6.2 V nominal reference applications |
| Zener Impedance (ZZT) | ≤10 Ω at IZT = 5 mA - ensures <±60 mV output shift under ±60 mA load transients |
| Power Dissipation (PD) | 375 mW (FR-4, min pad) / 830 mW (1 cm² cathode pad) - determines thermal derating in compact PCB layouts |
| Temperature Coefficient (TC) | +0.4 to +3.7 mV/°C - enables predictable positive drift for temperature-compensated references |
| Reverse Leakage (IR) | ≤3 µA at VR = 4 V - guarantees low quiescent current in always-on monitoring circuits |
| Junction-to-Ambient RθJA | 150 °C/W with 1 cm² cathode pad - allows operation up to +125°C ambient in engine bay modules |
| Capacitance (CT) | ≤200 pF at f = 1 MHz, VR = 0 V - minimizes signal distortion in high-frequency clamp applications |
Pinout & Package
Package: SOD123F - flat-lead, low-profile surface-mount package with molded green plastic body (UL 94V-0), matte tin-plated copper alloy leads, and cathode band polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Zener breakdown return path | Connected to lower-potential node; forms current sink during reverse-bias regulation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMSZ4685-7-F | Zener voltage 6.2 V ±5%, ZZT = 15 Ω, PD = 500 mW (SOD-123), no AEC-Q101 qualification | Suitable for commercial-grade power supplies but not automotive environments requiring PPAP or thermal cycling validation | Select when cost sensitivity outweighs automotive qualification requirements and thermal derating margin is >20% |
| BZX84-C6V2 | Zener voltage 6.2 V ±5%, ZZT = 60 Ω, PD = 300 mW (SOT-23), higher impedance and lower power rating | Acceptable for low-current biasing in non-automotive consumer devices where voltage stability under load is less critical | Choose only if board space permits SOT-23 and system-level thermal budget allows ≥30% higher junction temperature rise |
Compared with MMSZ4685-7-F and BZX84-C6V2, BZT52HC6V2WFQ offers superior thermal performance (150 °C/W vs. ~200–250 °C/W), lower dynamic impedance (10 Ω vs. 15–60 Ω), and mandatory AEC-Q101 compliance-making it the sole choice for production automotive voltage references requiring validated reliability and tight regulation.

FAQ
What is the maximum reverse voltage this Zener diode can withstand before breakdown?
The BZT52HC6V2WFQ has a nominal Zener voltage of 5.8–6.6 V at 5 mA test current, meaning it enters controlled reverse breakdown within that range. Its absolute maximum reverse voltage is not specified separately-it is designed to operate continuously in breakdown at rated power. Exceeding 830 mW (with proper thermal pad) risks irreversible junction damage.
Is this part suitable for use in high-humidity environments like under-hood automotive applications?
Yes. The SOD123F package uses UL 94V-0 compliant green molding compound with moisture sensitivity level 1 per J-STD-020, and the device is manufactured in IATF 16949 certified facilities with AEC-Q101 qualification-including rigorous humidity exposure and temperature cycling tests required for engine bay deployment.
How does the temperature coefficient affect regulation accuracy over automotive temperature ranges?
With a TC of +0.4 to +3.7 mV/°C, the Zener voltage increases by up to 0.45 V across –40°C to +125°C. This predictable positive drift allows designers to compensate using complementary negative-TC components or software calibration-enabling ±1% total regulation error in closed-loop systems.
Can this Zener diode replace a 6.2 V TL431-based shunt regulator in low-power applications?
No. The BZT52HC6V2WFQ is a passive two-terminal device without internal amplification or adjustable feedback. It lacks the 2.5 V reference, high open-loop gain, and programmable output of the TL431. It serves only as a fixed-voltage clamp or simple shunt reference-not as an active precision regulator.
