Product details
Overview
HZC9.1TRF-E from Renesas Electronics is a silicon epitaxial planar Zener diode optimized for surge absorption in low-power signal-line protection circuits, featuring a nominal Zener voltage of 9.1 V (8.56–9.55 V), 150 mW power dissipation, and ultra-small UFP (SC-79) surface-mount package with cathode/anode terminals. It delivers ESD robustness up to ±30 kV (IEC 61000-4-2 contact discharge) and dynamic resistance of ≤30 Ω at 5 mA.
For engineers reviewing the HZC9.1TRF-E datasheet, HZC9.1TRF-E pinout, HZC9.1TRF-E application, or HZC9.1TRF-E equivalent, key selection criteria include Zener voltage tolerance, temperature coefficient (−0.02 %/°C typical), junction temperature limit (150°C), and compatibility with automated SMT assembly due to its tape-and-reel packaging (UFP, PWSF0002ZA-A).
Technical Context
This device operates as a voltage-reference and transient-suppression element in reverse-biased configuration, with specified Zener current range of 0.5 mA (min) to 5 mA (test condition). Its low dynamic resistance (≤30 Ω) ensures stable clamping under fast transients, while the negative temperature coefficient (−0.02 %/°C) supports predictable voltage drift across −55°C to +150°C ambient.
The HZC9.1TRF-E uses silicon epitaxial planar construction with polyimide-board-compatible thermal profile, rated for storage between −55°C and +150°C and junction temperature up to 150°C. It is not intended for high-current surge suppression but targets precision clamping in sensor interfaces, I/O line protection, and low-energy logic-level stabilization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 8.56–9.55 V at IZ = 5 mA - defines precise clamping threshold for 9 V nominal rail protection |
| Power Dissipation (Pd) | 150 mW at Ta = 25°C - limits continuous power handling; derates linearly above 25°C per Fig.2 |
| Dynamic Resistance (rd) | ≤30 Ω at IZ = 5 mA - ensures minimal voltage shift during transient current surges |
| ESD Capability | ±30 kV (IEC 61000-4-2 contact) - enables robust handling of human-body-model electrostatic events |
| Reverse Current (IR) | ≤0.5 µA at VR = 6.0 V - guarantees low leakage in standby or high-impedance sensing nodes |
| Temperature Coefficient | −0.02 %/°C typical - provides predictable, moderate negative drift over operating range |
| Junction Temperature (Tj) | 150°C max - sets absolute thermal limit for reliability under sustained stress |

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-C9V1 (Nexperia) | Same Zener voltage (9.1 V), but higher Pd = 300 mW and larger SOD-523 package (1.7 × 1.3 mm) | Preferred where higher surge energy handling is required; less suitable for ultra-dense layouts | Select if board space allows larger footprint and >150 mW transient margin is needed |
| MMBZ5240BLT1G (onsemi) | 9.1 V Zener, SOT-23 package (3.0 × 1.4 mm), Pd = 350 mW, but only ±8 kV ESD rating | Used where higher power dissipation matters more than ESD robustness; requires external ESD protection | Choose when integrating into legacy SOT-23 footprints and ESD is managed elsewhere in the system |
Compared with BZX584-C9V1 and MMBZ5240BLT1G, the HZC9.1TRF-E offers superior ESD immunity (±30 kV vs. ±8–15 kV) in the smallest available footprint (UFP/SC-79), making it optimal for miniaturized, high-reliability signal-line protection where space and electrostatic robustness are critical.

FAQ
What is the Zener voltage tolerance of HZC9.1TRF-E?
The HZC9.1TRF-E has a guaranteed Zener voltage range of 8.56 V to 9.55 V at 5 mA test current, corresponding to ±5.5% tolerance around the nominal 9.1 V rating. This tight spread ensures consistent clamping behavior across production lots and supports reliable design margins in 9 V rail protection circuits.
Does HZC9.1TRF-E support automated SMT assembly?
Yes, the HZC9.1TRF-E is supplied in tape-and-reel format compatible with standard 8 mm carrier tape (EIA-481), enabling seamless integration into high-volume SMT lines. Its UFP (SC-79) package features precise terminal positioning and low mass (0.0016 g), ensuring reliable pick-and-place yield and reflow compatibility per J-STD-020.
What is the maximum junction temperature for HZC9.1TRF-E?
The absolute maximum junction temperature for HZC9.1TRF-E is 150°C, as specified in the Absolute Maximum Ratings table. Operation beyond this limit risks irreversible degradation of the silicon junction. Derating curves in Figure 2 confirm usable power dissipation down to zero mW at ~125°C ambient, assuming standard PCB copper area.
How does the temperature coefficient affect HZC9.1TRF-E performance?
The HZC9.1TRF-E exhibits a typical Zener voltage temperature coefficient of −0.02 %/°C, meaning its clamping voltage decreases by ~1.8 mV/°C near 25°C. This predictable negative drift aids system-level compensation in precision references and avoids thermal runaway in cascaded protection schemes.
Is HZC9.1TRF-E RoHS compliant and lead-free?
Yes, HZC9.1TRF-E complies with the EU RoHS Directive (2011/65/EU) and is manufactured as lead-free. Renesas confirms halogen-free and green material compliance per their environmental policy, with full substance declarations available upon request through official Renesas channels.
