Product details
Overview
HZM3.3NB1TL-E from Renesas Electronics is a silicon epitaxial planar Zener diode designed for precision voltage stabilization in low-power analog and reference circuits. It delivers a nominal zener voltage of 3.3 V (min 3.40 V, max 3.65 V at IZ = 5 mA), with dynamic resistance of 130 Ω, reverse current ≤20 µA at VR = 1.0 V, and power dissipation up to 200 mW in the MPAK package - commonly used in power supply feedback loops and sensor biasing networks.
For engineers reviewing the HZM3.3NB1TL-E datasheet, HZM3.3NB1TL-E pinout, HZM3.3NB1TL-E application, or HZM3.3NB1TL-E equivalent, key selection criteria include its B1-grade voltage tolerance (±5% typical), low-temperature-coefficient performance near zero crossing (~0.01 mV/°C at 3.3 V), SC-59A-compatible footprint, and suitability for high-density SMT assembly in industrial and consumer power management designs.
Technical Context
This device operates as a two-terminal shunt regulator, maintaining stable output voltage across varying load and input conditions via controlled reverse-biased breakdown. Its epitaxial planar construction ensures consistent zener voltage distribution and tight grading (B1 tolerance band), while the MPAK package supports thermal dissipation up to 150 °C junction temperature.
The HZM3.3NB1TL-E exhibits a near-zero temperature coefficient (γZ ≈ +0.01 mV/°C) at 3.3 V, minimizing drift over ambient temperature ranges (–55 °C to +150 °C storage). It is characterized under pulsed test conditions (Pw = 40 ms), ensuring reliable DC and transient regulation without thermal runaway in low-duty-cycle applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.40 V to 3.65 V at IZ = 5 mA - defines precise regulation window for 3.3 V rail referencing. |
| Dynamic Resistance (rd) | 130 Ω max - determines output impedance and load regulation sensitivity. |
| Reverse Current (IR) | ≤20 µA at VR = 1.0 V - ensures low leakage in standby or high-impedance bias networks. |
| Power Dissipation (Pd) | 200 mW - sets maximum continuous power handling at Ta = 25 °C; derates linearly above. |
| Junction Temperature (Tj) | 150 °C max - enables operation in thermally constrained PCB layouts with minimal heatsinking. |
| Package | MPAK (JEITA PLSP0003ZC-A, SC-59A equivalent) - 3-pin surface-mount footprint with 1.0 mm × 1.3 mm body size. |
| Zener Tempco (γZ) | +0.01 mV/°C - provides minimal voltage drift over temperature, critical for precision references. |
Pinout & Package
MPAK package (JEITA code PLSP0003ZC-A), also known as SC-59A, is a 3-pin surface-mount plastic package with 1.0 mm × 1.3 mm body dimensions, 0.65 mm lead pitch, and 0.35–0.5 mm lead width. Designed for high-density placement and reflow compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage stabilization applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C3V3 (Diodes Inc.) | Same nominal VZ (3.3 V), but wider tolerance (±5% min/max not specified per grade); rd = 95 Ω typ, Pd = 300 mW. | Higher power rating allows greater current headroom; less precise grading limits use in tight-margin feedback loops. | Select when higher surge capability is needed and ±5% system tolerance suffices. |
| MMSZ4685 (ON Semiconductor) | VZ = 3.3 V (3.14–3.47 V), rd = 130 Ω max, Pd = 350 mW, SOD-123 package (larger than MPAK). | Larger footprint increases board area; higher Pd supports higher continuous current but requires more layout space. | Choose when thermal margin is critical and PCB real estate permits SOD-123 placement. |
Compared with BZX84-C3V3 and MMSZ4685, the HZM3.3NB1TL-E offers tighter B1-grade voltage binning and SC-59A footprint optimization for ultra-dense layouts, though at lower absolute power rating - making it ideal for space-constrained, precision-regulated subsystems rather than high-current clamping.

FAQ
What is the exact zener voltage range for HZM3.3NB1TL-E at 5 mA test current?
The HZM3.3NB1TL-E has a guaranteed zener voltage range of 3.40 V to 3.65 V when tested at IZ = 5 mA, per its B1 grade designation in the Renesas R07DS0358EJ0600 datasheet. This tighter tolerance band distinguishes it from standard B-grade variants (e.g., HZM3.3NB2TL-E: 3.25–3.50 V) and supports higher-accuracy regulation in feedback and reference applications.
Is Pin 1 of HZM3.3NB1TL-E electrically connected internally?
No - Pin 1 of the HZM3.3NB1TL-E is designated NC (No Connect) and is internally unconnected. The device functions as a two-terminal Zener diode using only Pins 2 (Anode) and 3 (Cathode). Pin 1 must remain unconnected on the PCB to avoid unintended parasitic coupling or mechanical stress on the die bond wire.
What is the maximum allowable reverse current for HZM3.3NB1TL-E at 1.0 V?
The maximum reverse current for HZM3.3NB1TL-E is 20 µA when measured at VR = 1.0 V, as specified in the Electrical Characteristics table on page 2 of the R07DS0358EJ0600 datasheet. This low leakage supports high-impedance bias networks and minimizes quiescent power loss in battery-powered or standby-critical circuits.
Can HZM3.3NB1TL-E be used in place of a standard 3.3 V Zener diode like 1N4728A?
No - the HZM3.3NB1TL-E is not a drop-in replacement for through-hole diodes such as 1N4728A. It uses a 3-pin MPAK (SC-59A) package with Pin 1 NC, whereas 1N4728A is DO-41 packaged with two terminals. Layout, soldering, and thermal design differ significantly; redesign is required to accommodate the surface-mount footprint and pinout.
What is the temperature coefficient behavior of HZM3.3NB1TL-E near its 3.3 V operating point?
The HZM3.3NB1TL-E exhibits a temperature coefficient (γZ) of approximately +0.01 mV/°C at 3.3 V, as shown in Figure 2 of the datasheet. This near-zero crossing makes it exceptionally stable over temperature - far superior to lower-voltage Zeners (<2.4 V, negative tempco) or higher-voltage types (>5.6 V, positive tempco) - ideal for precision references where drift must be minimized.
