Product details
Overview
HZC6.2Z4TRF-E from Renesas Electronics is a silicon epitaxial planar Zener diode designed for surge absorption in low-power signal line protection. It delivers a nominal zener voltage of 6.2 V (min 5.86 V, max 6.53 V) at 5 mA, with dynamic resistance of 50 Ω, power dissipation of 150 mW, and ESD capability of ±30 kV (IEC 61000-4-2). It is used in I/O port transient suppression for microcontroller-based industrial sensors.
For engineers reviewing the HZC6.2Z4TRF-E datasheet, HZC6.2Z4TRF-E pinout, HZC6.2Z4TRF-E application, or HZC6.2Z4TRF-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 above 25°C ambient.
Technical Context
The HZC6.2Z4TRF-E operates as a voltage-reference clamp in reverse-biased mode, leveraging epitaxial planar junction technology for stable breakdown characteristics. Its 50 Ω dynamic resistance ensures tight voltage regulation under transient current surges up to 5 mA, while the −55°C to +150°C storage temperature range supports wide-environment deployment.
Designed specifically for surface-mount surge absorb applications, it features a cathode-marked two-terminal configuration in the UFP (Ultra small Flat Lead Package), with no internal series resistance or integrated TVS structure - functioning purely as a discrete zener element without integrated capacitance or bidirectional symmetry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.86–6.53 V at IZ = 5 mA; defines precise clamping threshold for 6.2 V nominal rail protection |
| Dynamic Resistance (rd) | 50 Ω max at IZ = 5 mA; ensures minimal voltage rise during transient current injection |
| Power Dissipation (Pd) | 150 mW at Ta = 25°C; limits continuous dissipation; derates linearly above 25°C per Fig.2 |
| ESD Capability | ±30 kV per IEC 61000-4-2 (C = 150 pF, R = 330 Ω); qualifies for high-level system-level ESD immunity |
| Junction Temperature (Tj) | 150°C max; sets absolute thermal limit for reliability under surge duty cycles |
| Reverse Current (IR) | 2.0 µA max at VR = 3.0 V; guarantees low leakage in standby signal lines |

Equivalent & Alternatives
The following parts are listed as comparable options for similar zener diode surge absorption applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5234BS-7-F | Zener voltage 6.2 V (same nominal), but higher dynamic resistance (70 Ω), lower ESD rating (±25 kV), and SOT-323 package (larger footprint) | Suitable for general-purpose clamping where board space is less constrained and ESD requirement is ≤±25 kV | Select when cost sensitivity outweighs ESD margin and size constraints |
| BZX84-C6V2 | 6.2 V zener, but rated only to 250 mW Pd, higher leakage (5 µA at 4.0 V), and SOT-23 package (1.3 mm taller) | Applicable in non-safety-critical consumer electronics where thermal headroom and leakage are less critical | Choose if higher power handling is needed and UFP height restriction does not apply |
Compared with MMBZ5234BS-7-F and BZX84-C6V2, the HZC6.2Z4TRF-E offers superior ESD immunity (±30 kV), tighter zener tolerance (±5.3%), and smallest package volume - making it optimal for space-limited, high-reliability industrial sensor nodes requiring repeatable clamping performance.

FAQ
What is the exact zener voltage tolerance of HZC6.2Z4TRF-E at 5 mA test current?
The HZC6.2Z4TRF-E has a guaranteed zener voltage range of 5.86 V to 6.53 V when tested at IZ = 5 mA and Ta = 25°C. This ±5.3% tolerance reflects manufacturing control for precision clamping applications and is confirmed in the Electrical Characteristics table on page 2 of the official Renesas datasheet REJ03G1204-0200.
Does HZC6.2Z4TRF-E meet IEC 61000-4-2 ESD requirements?
Yes, the HZC6.2Z4TRF-E is rated for ±30 kV contact discharge per IEC 61000-4-2 (C = 150 pF, R = 330 Ω, 10 pulses in both polarities), as specified in the Electrical Characteristics table. This exceeds standard industrial immunity requirements and is validated in Renesas' characterization testing documented in the HZC Series datasheet.
What is the thermal derating behavior of HZC6.2Z4TRF-E above 25°C ambient?
The HZC6.2Z4TRF-E power dissipation derates linearly above 25°C ambient, reaching zero at approximately 125°C, as shown in Fig.2 (Power Dissipation vs. Ambient Temperature) on page 4 of the datasheet. The slope is −1.2 mW/°C, meaning at 75°C ambient, usable Pd is reduced to ~90 mW - critical for sealed enclosure designs.
Is HZC6.2Z4TRF-E suitable for bidirectional transient suppression?
No, the HZC6.2Z4TRF-E is a unidirectional zener diode with defined anode and cathode terminals. It clamps only when cathode voltage exceeds anode voltage by ≥6.2 V. For bidirectional protection (e.g., AC signal lines), a back-to-back pair or dedicated TVS array is required - the HZC6.2Z4TRF-E alone does not provide symmetrical clamping.
What packaging format is used for HZC6.2Z4TRF-E, and is it compatible with standard SMT pick-and-place?
HZC6.2Z4TRF-E is supplied in embossed carrier tape conforming to EIA-481, with 3,000 units per reel. Its UFP package (SC-79 footprint) is fully compatible with standard 0402-class SMT placement equipment using standard nozzle tooling and vision alignment - confirmed by Renesas' packaging specification PWSF0002ZA-A.
