Product details
Overview
P6SMB36C from Taiwan Semiconductor is a bidirectional 600W surface-mount transient voltage suppressor (TVS) diode designed for overvoltage protection in DC power lines and signal paths. It features a breakdown voltage range of 32.4–39.6 V at 1.0 mA test current, clamps to ≤52.0 V at 12.0 A peak pulse current, and operates within -55°C to +150°C junction temperature. It is used in switching mode power supplies and industrial adapters to absorb ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the P6SMB36C datasheet, P6SMB36C pinout, P6SMB36C application, or P6SMB36C equivalent, this page delivers verified electrical specs, DO-214AA package dimensions, clamping behavior under 10/1000 µs surge, bidirectional conduction characteristics, and direct alternatives with documented VBR, VC, and IPPM differences.
Technical Context
The P6SMB36C implements a glass-passivated silicon avalanche junction optimized for fast transient response (<1.0 ps rise time from 0 V to VBR(min)) and low leakage (<1 µA @ 30.8 V). Its bidirectional configuration enables symmetrical clamping in AC-coupled or floating systems without polarity constraints.
Thermally, it delivers RθJC = 10°C/W and RθJA = 55°C/W, supporting sustained operation up to 150°C junction temperature. It meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements in its DO-214AA molded case.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 32.4 V / 39.6 V at 1.0 mA - defines guaranteed avalanche initiation window under standardized test conditions |
| VWM | 30.8 V - maximum continuous reverse operating voltage before significant leakage begins |
| VC @ IPPM | ≤52.0 V at 12.0 A (10/1000 µs) - peak clamped voltage during worst-case surge, critical for downstream IC survivability |
| PPPSM | 600 W - non-repetitive peak pulse power handling per single transient event |
| IR @ VWM | <1 µA - ultra-low reverse leakage ensures minimal standby power loss in battery-backed or high-impedance circuits |
| TJ(max) | +150°C - enables use in under-hood automotive modules and enclosed industrial power converters |
| Package | DO-214AA (SMB) - industry-standard surface-mount outline with 0.090 g mass and matte tin-plated leads |
Pinout & Package
DO-214AA (SMB) package: molded epoxy case with cathode band marking; terminals are matte tin-plated, solderable per J-STD-002; polarity indicated by molded cathode band (bidirectional operation means band denotes common reference, not unidirectional anode/cathode).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (marked side) | Transient return path (bidirectional) | Functions as cathode during positive transients and anode during negative transients - no fixed polarity required in layout |
| Cathode (band side) | Transient return path (bidirectional) | Same physical terminal as Anode; bidirectional symmetry eliminates need for orientation-aware PCB placement |
Key Features
| Feature | Design Value |
|---|---|
| ISO 7637-2 compliance | Validated against Pulse 1 (inductive load dump), Pulse 2a/2b (battery disconnect), and Pulse 3a/3b (switching noise) - suitable for automotive 12 V/24 V subsystems |
| Fast response time | <1.0 ps from 0 V to VBR(min) - clamps before sensitive logic or analog circuitry experiences overvoltage stress |
| Moisture sensitivity level | MSL Level 1 (per J-STD-020) - no bake requirement prior to reflow, enabling direct placement in high-volume SMT lines |
| Halogen-free construction | Complies with IEC 61249-2-21 - meets environmental mandates for RoHS-compliant industrial and consumer electronics |
| Low profile footprint | DO-214AA height ≤2.6 mm - fits beneath low-clearance heatsinks and in space-constrained AC-DC adapter PCBs |
Applications
| Automotive Infotainment Power Rails | Industrial SMPS Input Stage |
|---|---|
Use Scenario: Protecting USB-C PD controller and display interface ICs from load-dump transients in vehicle head units. IC Role / Device Role / Timing Role: Bidirectional TVS placed across 12 V supply rail upstream of DC-DC converters to clamp ISO 7637-2 Pulse 1 (−120 V, 50 ms) and Pulse 2b (+100 V, 50 ms). Use Value: Clamps to ≤52.0 V during 12.0 A surge, ensuring downstream 5 V/3.3 V regulators remain within absolute maximum ratings. | Use Scenario: Safeguarding primary-side MOSFET gate drivers and feedback optocouplers in 200 W industrial AC-DC power supplies. IC Role / Device Role / Timing Role: Mounted across bulk capacitor input to suppress line-induced surges (IEC 61000-4-5 Level 3) and switching noise spikes. Use Value: 600 W peak power rating absorbs 10/1000 µs transients without degradation, maintaining long-term reliability in 24/7 factory automation equipment. |
| Medical Equipment Battery Backup Circuits | Point-of-Sale Terminal DC Inputs |
Use Scenario: Shielding supercapacitor-based backup rails in portable ultrasound devices from ESD and cable discharge events. IC Role / Device Role / Timing Role: Placed between Li-ion battery output and backup regulator to prevent reverse-polarity misconnection damage and transient coupling. Use Value: Bidirectional conduction handles ±39.6 V breakdown symmetrically, eliminating need for dual-diode solutions and reducing BOM count. | Use Scenario: Securing 24 V DC input of retail kiosks exposed to frequent hot-plug/unplug cycles and nearby motor drives. IC Role / Device Role / Timing Role: Installed at connector entry point to shunt induced surges before reaching mainboard LDOs and microcontroller I/O. Use Value: VWM = 30.8 V allows safe operation across full 24 V ±20% tolerance while clamping sub-52 V - preserving 3.3 V logic integrity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36CA (Bourns) | VBR = 40.0–44.2 V; VC = 58.1 V @ 10.3 A; same DO-214AA package | Higher clamping voltage reduces margin for 3.3 V logic protection but offers tighter VBR tolerance | Select when tighter VBR distribution is prioritized over lowest possible clamping voltage |
| 1.5SMC36CA (ON Semiconductor) | VBR = 38.0–42.0 V; VC = 58.1 V @ 10.3 A; DO-214AB (SMC) package (larger footprint) | Larger SMC package increases board area use but improves thermal dissipation for repetitive surges | Select when higher thermal mass is needed for frequent transient exposure in outdoor signage controllers |
Compared with P6SMB36C, SMBJ36CA provides tighter VBR control but sacrifices 6.1 V in clamping headroom, while 1.5SMC36CA trades compact DO-214AA size for enhanced thermal robustness - choice depends on layout space, clamping margin, and surge repetition rate.

FAQ
What is the breakdown voltage range of the P6SMB36C?
The P6SMB36C has a minimum breakdown voltage (VBR) of 32.4 V and a maximum of 39.6 V, measured at 1.0 mA test current per ANSI/IEEE C62.35. This range reflects manufacturing tolerance and ensures reliable avalanche initiation across all units of P6SMB36C under standardized conditions.
Is the P6SMB36C unidirectional or bidirectional?
The P6SMB36C is a bidirectional TVS diode, indicated by the "C" suffix. It provides symmetrical clamping for both positive and negative transients, making it suitable for AC-coupled lines, floating grounds, and applications where polarity cannot be guaranteed - unlike unidirectional variants such as P6SMB36.
What is the maximum clamping voltage of the P6SMB36C at rated surge current?
The P6SMB36C clamps to a maximum of 52.0 V when subjected to a 10/1000 µs waveform with a peak pulse current of 12.0 A. This value is critical for determining whether downstream components remain within their absolute maximum voltage ratings during surge events.
Does the P6SMB36C meet automotive transient standards?
Yes, the P6SMB36C meets ISO 7637-2 requirements for Pulse 1 (inductive load dump), Pulse 2a/2b (battery disconnection), and Pulse 3a/3b (switching noise), making it suitable for 12 V and 24 V automotive subsystems including infotainment, body control modules, and ADAS power rails.
What is the thermal resistance from junction to ambient for the P6SMB36C?
The P6SMB36C has a junction-to-ambient thermal resistance (RθJA) of 55°C/W under standard JEDEC test conditions. This value assumes a 1-inch² copper pad on FR-4 PCB and is essential for estimating steady-state temperature rise during continuous power dissipation scenarios.
