Product details
Overview
BZW04-213RL from STMicroelectronics is a unidirectional transient voltage suppression (TVS) diode in DO-15 package, designed for high-energy ESD and surge protection in power rails and signal lines. It features a standoff voltage (VRM) of 213 V, clamping voltage (VCL) of 348 V at 1.7 A (10/1000 µs), peak pulse power of 400 W, and operates up to 175 °C junction temperature - deployed in industrial AC/DC converters and telecom power supplies.
For engineers reviewing the BZW04-213RL datasheet, BZW04-213RL pinout, BZW04-213RL application, or BZW04-213RL equivalent, key selection criteria include verified clamping performance at elevated Tj, low dynamic resistance (RD = 1.9 Ω), IEC 61000-4-2 ±30 kV contact discharge compliance, and DO-15 thermal derating behavior above 125 °C.
Technical Context
This TVS diode uses planar silicon junction technology optimized for low leakage (<1 µA at VRM) and stable VBR over temperature (αT = 10 × 10⁻⁴ /°C). Its unidirectional configuration provides asymmetric clamping - forward conduction only during reverse overvoltage events - enabling precise rail protection without interfering with normal DC bias paths.
The device meets IEC 61000-4-4 Level 4 (4 kV) and exceeds IEC 61000-4-2 Level 4 (±30 kV air/contact discharge). Thermal design relies on FR4 PCB copper area under leads, with Rth(j-a) dropping from 4.5 °C/W (no copper) to <2.0 °C/W at 3 cm² per lead - critical for sustained 230 W dissipation at Tj = 175 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage (VRM) | 213 V - maximum continuous reverse operating voltage before breakdown; sets minimum system rail margin for reliable blocking. |
| Breakdown Voltage (VBR) | 237–264 V at 1 mA - defines onset of avalanche conduction; tight tolerance ensures predictable trigger point across temperature. |
| Clamping Voltage (VCL) | 348 V at 1.7 A (10/1000 µs) - peak voltage seen by protected circuit during surge; directly limits stress on downstream MOSFETs or controllers. |
| Peak Pulse Power (PPP) | 400 W (10/1000 µs), 230 W at Tj = 175 °C - determines single-event energy handling; derates linearly above 25 °C per Figure 3. |
| Dynamic Resistance (RD) | 1.9 Ω - governs VCL rise vs. current (ΔV = RD × ΔI); lower RD enables tighter clamping under high di/dt transients. |
| Junction Capacitance (CJ) | 11 pF at VR = 0 V - minimal signal distortion in data-line protection; confirmed via 1 MHz measurement per Figure 7. |
| Leakage Current (IRM) | 1 µA max at VRM - ensures negligible standby power loss in high-impedance sensing or battery-backed circuits. |
Pinout & Package
DO-15 (JEDEC DO-204AC) axial-leaded package with matte tin-plated leads. Cathode indicated by band marking; anode is unmarked end. Lead spacing (B) = 26–31 mm, body diameter (D) = 0.71–0.88 mm, overall length (A) = 6.05–6.75 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Forward current entry / Reverse voltage reference | Connects to protected line's lower-potential side (e.g., GND or return path); defines polarity-sensitive clamping direction. |
| Cathode (banded end) | Avalanche conduction node / Clamping output | Connected to higher-potential rail (e.g., +24 V, +48 V); sinks surge current into ground when VAK exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature operation | Rated for continuous use up to Tj = 175 °C - enables placement near hot components (e.g., MOSFET heatsinks) without derating penalties. |
| Low dynamic resistance | RD = 1.9 Ω - reduces clamping voltage overshoot during fast-rising surges (e.g., lightning-induced ring waves). |
| ESD robustness | ±30 kV contact/air discharge (IEC 61000-4-2) - protects front-end interfaces (RS-485, CAN, Ethernet PHY) without external shielding. |
| Thermal stability | VBR tempco αT = 10 × 10⁻⁴ /°C - ensures <±5% VBR shift from −55 °C to +175 °C, critical for wide-temperature industrial deployments. |
| Lead-free reflow compatibility | Meets J-STD-020 MSL Level 1 - supports standard Pb-free reflow profiles up to 245 °C peak, no pre-baking required. |
Applications
| Industrial AC/DC Power Supplies | Telecom DC Distribution Panels |
|---|---|
|

|
Use Scenario: Protection of IGBT gate drivers and bus voltage sense nodes against inductive kickback from 3-phase motor windings. IC Role / Device Role / Timing Role: Fast-response unidirectional clamp shunting energy from snubber networks into local ground planes. Use Value: RD = 1.9 Ω ensures clamping voltage stays below 350 V during 100 A/µs di/dt events, preserving driver IC SOA margins. |
Use Scenario: Input-stage protection for polyphase electricity meters connected to overhead distribution lines prone to induced surges. IC Role / Device Role / Timing Role: Primary overvoltage limiter on voltage divider inputs feeding ADCs and isolation amplifiers. Use Value: 11 pF junction capacitance avoids phase error in 50/60 Hz metrology paths while sustaining 30 kV ESD strikes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ210A | DO-214AA package; 210 V VRM; 347 V VCL at 1.7 A; 600 W PPP (10/1000 µs) | Higher power rating but larger footprint; requires >2× PCB area vs. DO-15 | Select when system-level surge testing exceeds 400 W and board space permits SMB footprint. |
| P6KE220A | DO-15 package; 220 V VRM; 356 V VCL at 1.6 A; 600 W PPP (10/1000 µs); Tj max = 150 °C | Lower max junction temperature; higher VCL; wider VBR tolerance (±10%) | Choose only if legacy P6KE footprint reuse is mandatory and 175 °C operation is not required. |
Compared with SMBJ210A and P6KE220A, BZW04-213RL delivers superior thermal endurance (175 °C vs. 150 °C), tighter VBR control (±5.5% vs. ±10%), and lower dynamic resistance - making it optimal for compact, high-reliability industrial power designs where thermal margin and clamping precision are critical.

FAQ
What is the maximum clamping voltage for BZW04-213RL under a 10/1000 µs surge?
The maximum clamping voltage (VCL) is 348 V at 1.7 A for a 10/1000 µs waveform, measured at Tamb = 25 °C. This value increases with junction temperature at a rate defined by αT = 10 × 10⁻⁴ /°C, reaching ~365 V at Tj = 175 °C per DS0660 Figure 5.
Can BZW04-213RL be used in bidirectional protection configurations?
No - BZW04-213RL is a unidirectional TVS diode, marked with a single cathode band. Bidirectional variants exist in the same family (e.g., BZW04-213B), but they feature symmetric clamping and dual-band marking. Using this part in reverse-biased mode risks permanent breakdown.
How does thermal derating affect its 400 W rating?
The 400 W peak pulse power applies only at Tj = 25 °C. Per Figure 3 in DS0660, power capability drops linearly to 230 W at Tj = 175 °C. Effective derating requires PCB copper area ≥2.5 cm² per lead to maintain Rth(j-a) ≤3.0 °C/W during repeated surges.
Is BZW04-213RL compliant with RoHS and REACH?
Yes - it carries STMicroelectronics' ECOPACK2 designation, confirming full compliance with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Matte tin plating and halogen-free epoxy meet J-STD-020 MSL Level 1 and UL94 V0 flammability requirements.
