Product details
Overview
HZC8.2TRF-E from Renesas Electronics is a silicon epitaxial planar Zener diode designed for surge absorption in low-power signal and power rail protection circuits, with a nominal zener voltage of 8.2 V (7.76–8.64 V), 150 mW power dissipation, 30 Ω dynamic resistance at 5 mA, and ESD capability of ±30 kV (IEC 61000-4-2, C=150 pF, R=330 Ω). It is used in consumer electronics power supply clamping and I/O line transient suppression.
For engineers reviewing the HZC8.2TRF-E datasheet, HZC8.2TRF-E pinout, HZC8.2TRF-E application, or HZC8.2TRF-E equivalent, key selection criteria include zener voltage tolerance (±5.5%), temperature coefficient (−0.03 %/°C at 8.2 V), ultra-small UFP package footprint (1.7 × 1.2 × 0.6 mm), cathode-anode polarity marking, and compliance with JEITA SC-79 standard.
Technical Context
The HZC8.2TRF-E operates as a precision voltage reference and transient voltage suppressor in reverse-biased mode, delivering stable clamping at 8.2 V under 5 mA test current. Its planar epitaxial construction ensures tight VZ distribution and low leakage (≤0.5 µA at 5.0 V).
Designed for surface-mount applications, it features a single-junction structure with a maximum junction temperature of 150°C and storage range from −55°C to +150°C. The device exhibits a negative temperature coefficient of −0.03 %/°C, enabling predictable drift behavior across industrial ambient conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 7.76–8.64 V at IZ = 5 mA - defines clamping threshold for overvoltage protection on 5–9 V rails |
| Power Dissipation (Pd) | 150 mW at Ta = 25°C - limits continuous surge energy handling without derating |
| Dynamic Resistance (rd) | 30 Ω max at IZ = 5 mA - determines voltage regulation stiffness during transient events |
| Reverse Leakage (IR) | ≤0.5 µA at VR = 5.0 V - ensures minimal standby current in always-on protection circuits |
| ESD Capability | ±30 kV (HBM, C=150 pF, R=330 Ω) - qualifies for direct I/O port protection without external series impedance |
| Temperature Coefficient | −0.03 %/°C at 8.2 V - enables predictable VZ drift compensation in temperature-sensitive designs |

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 |
|---|---|---|---|
| BZX584-C8V2 | Same VZ (8.2 V), but SOD-523 package (1.3 × 0.85 mm); higher rd (50 Ω); lower Pd (200 mW derated) | Higher board density possible, but reduced surge energy handling due to smaller thermal mass | Select when PCB area is critical and peak pulse power <100 mW; verify thermal margin in reflow profile. |
| MMSZ5238B | VZ = 8.2 V, SOD-123 package (3.7 × 1.6 mm); rd = 35 Ω; Pd = 500 mW; no specified ESD rating | Higher power handling supports longer surge durations, but lacks documented ±30 kV ESD immunity | Select for high-energy transients where ESD is mitigated upstream; avoid in direct-connect I/O applications. |
Compared with BZX584-C8V2 and MMSZ5238B, the HZC8.2TRF-E uniquely balances ultra-compact size, industry-leading ±30 kV ESD robustness, and tight 5.5% VZ tolerance-making it optimal for space-limited, high-reliability consumer interfaces where both form factor and electrostatic immunity are design-critical.

FAQ
What is the exact zener voltage tolerance of the HZC8.2TRF-E?
The HZC8.2TRF-E has a guaranteed zener voltage range of 7.76 V to 8.64 V at 5 mA test current, representing a ±5.5% tolerance about the nominal 8.2 V value. This specification is measured per Renesas' REJ03G1204-0200 datasheet Rev.2.00 and applies across the full operating temperature range of −25°C to +85°C.
Does the HZC8.2TRF-E meet JEDEC or JEITA package standards?
Yes, the HZC8.2TRF-E uses the Ultra Small Flat Lead (UFP) package, which conforms to JEITA package code SC-79 and Renesas internal code PWSF0002ZA-A. Its mechanical dimensions (1.7 × 1.2 × 0.6 mm) and terminal layout match SC-79 requirements, ensuring compatibility with standard SMT pick-and-place equipment and reflow profiles.
Can the HZC8.2TRF-E be used as a voltage reference in precision analog circuits?
The HZC8.2TRF-E is not optimized for precision voltage reference use due to its relatively high dynamic resistance (30 Ω) and moderate temperature coefficient (−0.03 %/°C). While usable in non-critical biasing, the HZC8.2TRF-E is primarily intended for surge suppression-not low-drift reference applications. For precision references, consider dedicated bandgap or buried-zener ICs.
What is the meaning of the 'TRF-E' suffix in HZC8.2TRF-E?
The 'TRF-E' suffix denotes tape-and-reel packaging with embossed carrier tape (E-type), standard for automated SMT assembly. 'TR' indicates tape-and-reel format, and 'F' specifies the taping method per Renesas' ordering convention. This ensures consistent orientation (cathode mark visible), part count accuracy, and compatibility with high-speed placement machines.
Is the HZC8.2TRF-E rated for automotive applications?
No, the HZC8.2TRF-E is classified as a Standard-grade Renesas product, intended for consumer, office, and communications equipment-not automotive or safety-critical systems. It does not meet AEC-Q200 stress testing requirements. For automotive-grade Zener diodes, consult Renesas' "Automotive" or "High Quality" product lines with explicit AEC qualification.
