Product details
Overview
1N5356BRL from onsemi is a 5 W axial-lead Zener diode with nominal zener voltage of 19 V (±5%), maximum zener impedance of 65 Ω at 3 mA test current, 0.5 mA leakage current at 14.4 V, and surge rating of 250 A at 8.3 ms. It operates across −65 °C to +200 °C and is used for precision voltage regulation in DC power supplies and overvoltage protection circuits.
For engineers reviewing the 1N5356BRL datasheet, pinout, applications, or equivalent options, key selection criteria include zener voltage tolerance, thermal resistance (25 °C/W junction-to-lead), surge current capability, lead temperature limit (260 °C), and Pb-free compliance per JEDEC standards.
Technical Context
This device uses silicon-oxide passivated junction technology to achieve tight voltage tolerance (±5%), low zener impedance, and high ESD robustness (>16 kV HBM). Its axial-lead Surmetic 40 package enables reliable heat dissipation via lead conduction, with thermal resistance dependent on lead length (e.g., 25 °C/W at 3/8″).
The 1N5356BRL exhibits a positive temperature coefficient above 5 V, with typical TC of +0.075 mV/°C/V at 19 V. Regulation is specified at two test currents (10% and 50% of IZM), ensuring stable performance under varying load conditions in feedback and reference circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 18.05–19.95 V @ IZT = 3 mA - defines regulated output voltage window for precision references |
| Power Dissipation (PD) | 5 W @ TL = 25 °C - sets maximum continuous DC power handling before thermal derating |
| Zener Impedance (ZZT) | 65 Ω max @ IZT = 3 mA - determines AC regulation stability under dynamic load changes |
| Leakage Current (IR) | 0.4 mA max @ VR = 14.4 V - ensures minimal standby current in high-impedance bias networks |
| Surge Current (IRM) | 250 A peak @ 8.3 ms - supports transient overvoltage clamping without failure |
| Junction-to-Lead RθJL | 25 °C/W - enables thermal design using lead as primary heat path; derates 40 mW/°C above 25 °C |
| Operating Temperature | −65 °C to +200 °C - suitable for automotive under-hood and industrial environments with wide ambient swings |
Pinout & Package
Package: Axial-lead Surmetic 40, Case 017AA - void-free thermosetting plastic with corrosion-resistant leads, cathode indicated by band, mountable in any orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Zener cathode reference ground | Connected to circuit ground or lower-potential node; establishes reference polarity for reverse-bias operation |
| Cathode | Zener breakdown terminal / regulated output node | Connected to unregulated input; delivers stable 19 V output when reverse-biased above VZ |
Key Features
| Feature | Design Value |
|---|---|
| Pb-Free compliant packaging | Meets RoHS Directive 2011/65/EU; compatible with lead-free reflow and wave soldering processes |
| ESD robustness | Class 3 (>16 kV) per Human Body Model - reduces risk of field failure during handling and assembly |
| Tight voltage tolerance | ±5% zener voltage - eliminates need for post-production trimming in voltage reference designs |
| High surge capability | 180 W non-repetitive surge rating - withstands lightning-induced transients and inductive kickback |
| Stable temperature coefficient | +0.075 mV/°C/V typical at 19 V - enables predictable drift compensation in temperature-critical references |
Applications
| Industrial Power Supply Reference | Automotive Overvoltage Clamp |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5356B | Same electrical specs; differs only in packaging - bulk box (1000 units) vs. tape-and-reel (4000 units) | No functional difference; identical thermal, electrical, and reliability performance | Select 1N5356B for manual prototyping or low-volume assembly; choose 1N5356BRL for automated SMT line compatibility |
| BZX85C18 | 18 V nominal, ±5%, 1.3 W rating, DO-41 package - lower power, higher ZZT (100 Ω), no surge rating specified | Suitable only for low-power biasing; cannot replace 1N5356BRL in 5 W regulation or surge-clamp roles | Use BZX85C18 where space or cost constraints preclude axial-leaded 5 W devices; verify thermal margin at full load |
Compared with 1N5356B and BZX85C18, the 1N5356BRL delivers full 5 W power handling and validated 250 A surge immunity in a Pb-free axial package - making it the only option among the three qualified for industrial-grade transient suppression and continuous high-power regulation.

FAQ
What is the exact zener voltage range for 1N5356BRL at 3 mA test current?
The 1N5356BRL has a guaranteed zener voltage range of 18.05 V to 19.95 V when tested at IZT = 3 mA and TA = 25 °C. This ±5% tolerance is specified per JEDEC standard and applies to all B-suffix devices in the 1N53 series, including the 1N5356BRL.
Can 1N5356BRL be used in surface-mount assemblies?
No - the 1N5356BRL uses an axial-lead Surmetic 40 package (Case 017AA) with 0.330–0.350 inch body length and 0.130–0.145 inch diameter. It is not a surface-mount device and requires through-hole mounting with 3/8 inch lead length for thermal derating compliance. The 1N5356BRL is incompatible with SMT reflow profiles.
What is the maximum allowable lead temperature during soldering for 1N5356BRL?
The maximum lead temperature for soldering the 1N5356BRL is 260 °C, applied at a point 1/16 inch from the case for up to 10 seconds. Exceeding this limit risks internal bond damage or delamination. This specification is defined in the onsemi mechanical characteristics section and applies identically to all 1N53xxB devices including the 1N5356BRL.
How does the 1N5356BRL handle thermal derating above 25 °C?
The 1N5356BRL derates linearly at 40 mW/°C above 25 °C ambient, based on its 5 W maximum power dissipation at TL = 25 °C. For example, at 75 °C lead temperature, maximum power drops to 3 W. Derating follows the formula PD(TL) = 5 W − 0.04 W/°C × (TL − 25 °C), as confirmed in the Maximum Ratings table for the 1N5356BRL.
Is the 1N5356BRL RoHS-compliant and halogen-free?
Yes - the 1N5356BRL carries the "G" suffix indicating Pb-free packaging per EU RoHS Directive 2011/65/EU. While the datasheet confirms Pb-free construction and RoHS compliance, it does not specify halogen-free status; therefore, halogen content for the 1N5356BRL should be verified separately via onsemi's material declarations or IPC-1752 reports.
