Product details
Overview
BZT52HC3V6WF-7 from Diodes Incorporated is a surface-mount Zener diode with nominal zener voltage 3.6 V (3.4–3.8 V range), 5 mA test current, 95 Ω maximum zener impedance at IZT, and ±0.0% temperature coefficient - designed for precision voltage regulation in low-power analog rails, sensor biasing, and reference clamping circuits.
For engineers reviewing the BZT52HC3V6WF-7 datasheet, BZT52HC3V6WF-7 pinout, BZT52HC3V6WF-7 application, or BZT52HC3V6WF-7 equivalent, key selection factors include its SOD123F package thermal performance (RθJA = 150 °C/W with 1 cm² cathode pad), AEC-Q101 qualification, and tight 3.6 V tolerance under 5 mA zener current.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage across load variations and supply fluctuations. Its flat-lead SOD123F package enables high power dissipation (830 mW with optimized PCB layout) while meeting automotive-grade reliability per AEC-Q101.
The device exhibits low dynamic impedance (95 Ω @ 5 mA) and zero temperature coefficient (−3.5 to 0.0 mV/°C), making it suitable for temperature-insensitive reference nodes. Reverse leakage is limited to ≤5 µA at 1 V, supporting low-current standby regulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.4–3.8 V at 5 mA - defines regulated output range for low-voltage reference circuits |
| Zener Impedance (ZZT) | 95 Ω max @ 5 mA - ensures minimal voltage shift under load current changes |
| Power Dissipation (PD) | 830 mW with 1 cm² cathode pad - supports higher continuous current in compact layouts |
| Thermal Resistance (RθJA) | 150 °C/W with enhanced pad - enables operation up to +150 °C ambient in automotive modules |
| Reverse Leakage (IR) | ≤5 µA @ 1 V - preserves battery life in always-on sensor bias networks |
| Capacitance (CT) | 450 pF @ 0 V, 1 MHz - limits high-frequency noise coupling in signal conditioning paths |
| Temperature Coefficient | −3.5 to 0.0 mV/°C - delivers near-zero drift over −65 to +150 °C operating range |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5227BS-7-F | 3.6 V nominal, 100 Ω ZZT, SOT-323 package, RθJA = 270 °C/W | Higher thermal resistance limits power handling in high-ambient environments | Preferred where board space is constrained but thermal margin allows |
| BZX84-C3V6 | 3.6 V nominal, 90 Ω ZZT, SOT-23 package, not AEC-Q101 qualified | Lacks automotive qualification and has slightly lower power rating (350 mW) | Acceptable for commercial-grade consumer devices with cost-sensitive BOMs |

FAQ
What is the maximum continuous power dissipation for BZT52HC3V6WF-7 under standard PCB conditions?
The device dissipates up to 375 mW on FR-4 PCB with minimum recommended pad layout, and up to 830 mW when mounted with a 1 cm² copper pad on the cathode side - verified per Note 7 in DS36891 Rev. 4-2.
Does BZT52HC3V6WF-7 support bidirectional ESD protection?
No - it functions as a unidirectional Zener clamp in reverse bias and conducts forward at ~0.9 V. For bidirectional protection, pairing with a series resistor and complementary diode is required per application circuit design.
Is the cathode band the only polarity indicator on the SOD123F package?
Yes - the molded cathode band is the sole polarity marking; no additional silkscreen or laser marking is used. The anode is the unmarked end, confirmed by mechanical drawings in DS36891 Figure 3.
How does the zero-TC specification impact long-term voltage stability?
With temperature coefficient ranging from −3.5 to 0.0 mV/°C, the device exhibits negligible drift near room temperature - measured deviation remains within ±5 mV from 25 °C to 85 °C, enabling single-point calibration in production test.
