Product details
Overview
HZC2.0TRF-E from Renesas Electronics is a silicon epitaxial planar Zener diode optimized for surge absorption in low-voltage signal and power rail protection circuits, featuring a nominal zener voltage of 2.0 V (1.90–2.20 V), 150 mW power dissipation, and ultra-small UFP (SC-79) surface-mount package. It delivers 120 µA maximum reverse current at 0.5 V, 30 Ω typical dynamic resistance at 5 mA, and ±30 kV ESD capability per IEC 61000-4-2 (C = 150 pF, R = 330 Ω).
For engineers reviewing the HZC2.0TRF-E datasheet, HZC2.0TRF-E pinout, HZC2.0TRF-E application, or HZC2.0TRF-E equivalent, key selection considerations include its precise 2.0 V clamping threshold, low-temperature-coefficient performance (−0.05 %/°C typical), compatibility with automated SMT assembly due to tape-and-reel packaging, and suitability for space-constrained consumer and industrial electronics requiring robust transient suppression.
Technical Context
The HZC2.0TRF-E operates as a two-terminal voltage-reference clamp, leveraging epitaxial planar junction technology to achieve stable breakdown behavior under transient overvoltage conditions. Its design targets fast response to ESD and surge events while maintaining low leakage and tight VZ tolerance across temperature.
It functions exclusively in reverse-bias mode with cathode-anode polarity, exhibits a negative temperature coefficient (γZ ≈ −0.05 %/°C), and is rated for junction temperatures up to 150°C. The device is not intended for regulation in active bias circuits but for passive clamping in protection networks where predictable, repeatable breakdown onset is critical.
Key Specifications

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 |
|---|---|---|---|
| ON Semiconductor NZX2V0B | Same 2.0 V nominal VZ, but SOD-123 package (2.8 × 1.7 mm) and higher rd (50 Ω) | Less suitable for ultra-dense layouts; requires larger PCB footprint | Choose when legacy board space allows and higher surge energy rating (500 mW) is prioritized over size |
| Vishay PLZ2.0 | 2.0 V VZ, DO-35 glass package (4.5 × 1.8 mm), 500 mW Pd, but no ESD rating specified | Not qualified for IEC 61000-4-2; limited to non-portable industrial equipment | Prefer for high-energy, low-frequency surge scenarios where ESD immunity is secondary |
Compared with NZX2V0B and PLZ2.0, the HZC2.0TRF-E offers the smallest footprint, lowest dynamic resistance, and certified ±30 kV ESD performance-making it optimal for modern portable and space-constrained designs requiring guaranteed electrostatic robustness.

FAQ
What is the exact zener voltage tolerance of HZC2.0TRF-E at 5 mA test current?
The HZC2.0TRF-E has a guaranteed zener voltage range of 1.90 V to 2.20 V when tested at IZ = 5 mA and Ta = 25°C. This ±0.15 V tolerance ensures consistent clamping behavior across production lots and supports reliable interface-level protection for 2.0 V–2.5 V logic families. The HZC2.0TRF-E datasheet specifies this range in its Electrical Characteristics table under "Zener Voltage".
Is HZC2.0TRF-E rated for automotive applications?
The HZC2.0TRF-E is classified as a "Standard" quality grade device per Renesas' quality grading system and is intended for computers, office equipment, communications gear, and industrial robots-not for automotive transportation systems. It lacks AEC-Q200 qualification and is not approved for use in vehicles without explicit written consent from Renesas Electronics. For automotive-grade alternatives, consult Renesas' AEC-Q200-qualified Zener series.
Does HZC2.0TRF-E require external series resistance for safe operation?
No, the HZC2.0TRF-E does not require an external series resistor for basic ESD clamping, as its 150 mW power rating and 30 Ω dynamic resistance allow direct placement across protected nodes and ground. However, for sustained surge events exceeding IEC 61000-4-5 Level 3, a current-limiting resistor is recommended upstream to prevent junction overheating. The HZC2.0TRF-E datasheet provides derating curves for ambient temperature.
What does the "TRF" suffix indicate in HZC2.0TRF-E?
The "TRF" suffix denotes tape-and-reel packaging: "TR" = tape and reel, "F" = flat lead (UFP) variant. This format supports automated SMT placement with standard 8 mm carrier tape, 2 mm pocket pitch, and 3,000 units per reel. The HZC2.0TRF-E is supplied in this configuration to ensure compatibility with high-volume manufacturing lines.
Can HZC2.0TRF-E be used as a voltage reference in precision analog circuits?
No, the HZC2.0TRF-E is not designed or characterized for precision voltage reference use. Its zener voltage exhibits a −0.05 %/°C temperature coefficient and ±0.15 V initial tolerance-insufficient for stable reference applications. It is explicitly intended for surge absorption and transient clamping only. For precision references, Renesas offers dedicated bandgap or buried-zener ICs such as the uPC1093 or RA4M2-based reference solutions-not the HZC2.0TRF-E.
