Product details
Overview
HZC6.2Z4JTRF-E from Renesas Electronics is a silicon epitaxial planar Zener diode designed for surge absorption in low-power signal and power rail protection circuits. It delivers 6.2 V nominal Zener voltage (5.86–6.53 V), 2.0 µA maximum reverse current at 3.0 V, 50 Ω dynamic resistance at 5 mA, and ESD capability of ±30 kV (HBM, C = 150 pF, R = 330 Ω). It is used in I/O port transient suppression on microcontroller-based industrial sensors.
For engineers reviewing the HZC6.2Z4JTRF-E datasheet, HZC6.2Z4JTRF-E pinout, HZC6.2Z4JTRF-E application, or HZC6.2Z4JTRF-E equivalent, key selection criteria include Zener voltage tolerance, low dynamic impedance for clamping fidelity, ultra-small UFP package footprint, ESD robustness, and thermal derating behavior up to 150°C junction temperature.
Technical Context
This device operates as a two-terminal voltage reference and transient voltage suppressor, leveraging silicon epitaxial planar construction for stable breakdown characteristics. Its Zener voltage exhibits a temperature coefficient of approximately +0.03 %/°C near 6.2 V, and it is rated for 150 mW power dissipation at 25°C ambient with linear derating above 25°C.
The HZC6.2Z4JTRF-E is optimized for surface-mount surge absorb applications where space-constrained PCBs require fast-response, low-capacitance overvoltage protection. It is not intended for precision regulation or high-current shunt applications due to its 5 mA test current and limited power handling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.86–6.53 V at IZ = 5 mA - defines clamping threshold range for 6.2 V nominal rail protection |
| Reverse Current (IR) | ≤2.0 µA at VR = 3.0 V - ensures minimal leakage below clamping voltage |
| Dynamic Resistance (rd) | 50 Ω at IZ = 5 mA - enables tight voltage regulation during transient events |
| Power Dissipation (Pd) | 150 mW at Ta = 25°C - sets maximum steady-state energy handling before thermal shutdown |
| ESD Capability | ±30 kV per HBM (C = 150 pF, R = 330 Ω) - qualifies for robust electrostatic discharge immunity in end-user interfaces |
| Junction Temperature (Tj) | −55 to +150°C - supports operation in extended-temperature industrial environments |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to protected node (e.g., MCU I/O); carries surge current during clamping |
| 2 | Anode | Connected to ground or lower-potential reference; completes clamp path during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small UFP package | 1.70 × 1.20 mm footprint enables placement adjacent to IC pins without trace stubs |
| Taped delivery | Supports automated SMT assembly with standard 8 mm carrier tape (EIA-481) |
| High ESD robustness | ±30 kV HBM rating eliminates need for external ESD diodes in many Class-3B interface designs |
| Stable Zener temperature coefficient | +0.03 %/°C near 6.2 V minimizes clamping voltage drift across −40 to +85°C operating range |
Applications
| Industrial Sensor I/O Protection | USB Port ESD Clamp |
|---|---|
Use Scenario: Protecting analog input pins of 6.2 V-supplied temperature/humidity sensors from ESD and cable-induced transients. IC Role / Device Role / Timing Role: Two-terminal shunt clamp that diverts surge current away from sensitive ADC inputs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode surge absorb applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C6V2 | Same 6.2 V nominal Zener voltage but higher 90 Ω dynamic resistance; SOD-523 package (1.3 × 0.85 mm) | Lower clamping fidelity under fast transients; slightly smaller footprint | Prefer HZC6.2Z4JTRF-E when low rd is critical for sub-100 ns surges |
| MMSZ4687 | 6.2 V Zener with 100 mW Pd rating and 100 Ω rd; SOD-123 package (3.7 × 1.6 mm) | Larger footprint; lower power and higher impedance limit use in high-repetition surge scenarios | Choose HZC6.2Z4JTRF-E for space-constrained designs requiring 150 mW and 50 Ω performance |
Compared with BZX584-C6V2 and MMSZ4687, the HZC6.2Z4JTRF-E offers superior clamping sharpness (50 Ω vs. ≥90 Ω) and higher power margin (150 mW vs. ≤100 mW), making it preferred for compact industrial I/O protection where transient energy and board area are both constrained.

FAQ
What is the Zener voltage tolerance of HZC6.2Z4JTRF-E at 5 mA test current?
The HZC6.2Z4JTRF-E has a Zener voltage range of 5.86 V to 6.53 V at IZ = 5 mA, corresponding to ±5.2% tolerance around the nominal 6.2 V rating. This specification is guaranteed per the Renesas HZC Series datasheet Rev.2.00 (Jul 04, 2005), page 2, Electrical Characteristics table.
Does HZC6.2Z4JTRF-E meet industrial temperature requirements?
Yes, the HZC6.2Z4JTRF-E supports operation from −55°C to +150°C junction temperature and is rated for storage across the same range. Its "Standard" quality grade aligns with Renesas' classification for industrial robots, test equipment, and industrial sensors - confirmed in the datasheet's Quality Grade notice (page 1, Section 7).
What is the package type and lead-free status of HZC6.2Z4JTRF-E?
HZC6.2Z4JTRF-E uses the Ultra Small Flat Lead (UFP) package, JEITA code PWSF0002ZA-A, SC-79 compatible. It is RoHS-compliant and lead-free, as stated in Renesas' environmental compliance guidance (Section 10, page 1) and verified via Renesas' official product page and distributor listings.
Can HZC6.2Z4JTRF-E be used as a precision voltage reference?
No, the HZC6.2Z4JTRF-E is not designed for precision voltage reference applications. Its Zener voltage tolerance (±5.2%), temperature coefficient (+0.03 %/°C), and dynamic resistance (50 Ω) are optimized for surge absorption-not regulation stability. For precision references, Renesas offers the uPC1093 or RA4M1-series internal references instead of the HZC6.2Z4JTRF-E.
Is the HZC6.2Z4JTRF-E pinout compatible with other SC-79 Zener diodes?
Yes, the HZC6.2Z4JTRF-E follows the standard SC-79 pinout: Pin 1 = Cathode, Pin 2 = Anode, with cathode marked by a visible band. This matches industry-standard SC-79 Zeners including BZX584 and MMSZ series, enabling layout reuse where electrical specs permit substitution.
