Product details
Overview
P6SMB30CH from Taiwan Semiconductor is a bidirectional 600W surface-mount Transient Voltage Suppressor (TVS) diode in DO-214AA (SMB) package, with breakdown voltage range 27.0–33.0 V, clamping voltage 43.5 V at 14.0 A peak pulse current, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the P6SMB30CH datasheet, P6SMB30CH pinout, P6SMB30CH application, or P6SMB30CH equivalent, this device serves as a robust, low-profile ESD and surge protection solution for automotive power lines, industrial sensor interfaces, and lighting control circuits requiring ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance and <1 μA reverse leakage above 24.3 V.
Technical Context
The P6SMB30CH is a unidirectional/bidirectional TVS diode configured as a single die in a glass-passivated junction structure, enabling fast response time (<1.0 ps from 0 V to VBR(min)) and stable clamping under repetitive transients. Its bipolar construction (indicated by "CH" suffix) supports symmetrical protection in both directions without polarity dependency.
It operates across –55 °C to +150 °C junction temperature range, with thermal resistance RθJC = 10 °C/W and RθJA = 55 °C/W, and meets JESD201 Class 2 whisker resistance and J-STD-020 Moisture Sensitivity Level 1 - confirming suitability for lead-free reflow and high-reliability automated assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 27.0 V / 33.0 V - ensures reliable triggering above system stand-off voltage while accommodating manufacturing tolerance |
| VWM | 24.3 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA |
| VC @ IPPM | 43.5 V at 14.0 A - clamping voltage limits downstream IC stress during 10/1000 µs surge events |
| PPPSM | 600 W - peak pulse power rating per standard 10/1000 µs waveform, derated linearly above 25 °C ambient |
| IR @ VWM | <1 µA - ultra-low leakage preserves battery life and signal integrity in always-on circuits |
| TJ(max) | +150 °C - enables operation in under-hood automotive environments and high-power industrial enclosures |
| Package | DO-214AA (SMB) - surface-mount footprint compatible with IPC-7351B standard, 0.090 g weight, UL 94V-0 molding |
Pinout & Package

Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
|
Use Scenario: Protecting LIN bus transceivers and microcontroller I/O pins from load dump and alternator ripple in 12 V vehicle networks. IC Role / Device Role: Bidirectional clamping element placed between power rail and ground, shunting surges before reaching sensitive analog front-ends. Use Value: Clamps 43.5 V at 14 A, limiting voltage seen by downstream ICs below absolute maximum ratings while maintaining <1 µA leakage at 24.3 V. |
Use Scenario: Safeguarding 4–20 mA current loop receivers and RS-485 nodes against EFT bursts and lightning-induced surges in factory automation. IC Role / Device Role: Standoff voltage (24.3 V) aligns with 24 V industrial supply rails; symmetric conduction handles differential-mode transients. Use Value: Enables direct placement across signal lines without polarity concerns, reducing BOM count and layout complexity. |
| LED Driver Output Protection | Automotive Lighting Control |
|
Use Scenario: Suppressing inductive kickback from relay coils and solenoid drivers feeding LED arrays in architectural and signage lighting.

Use Value: 600 W peak power rating sustains repeated 10/1000 µs pulses without degradation; DO-214AA footprint fits tight thermal zones near drivers. |
Use Scenario: Shielding headlamp control modules from ISO 7637-2 Pulse 2b (battery disconnect) and Pulse 3b (capacitive coupling) transients. IC Role / Device Role: Primary surge suppression stage on 12 V input rail, preceding DC/DC converters and MCU power supplies. Use Value: AEC-Q101 qualification and +150 °C TJ(max) ensure reliability in sealed, thermally constrained lamp housings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ30CA (onsemi) | Same DO-214AC (SMA) package; 30 V nominal VBR, 48.4 V VC @ 12.4 A; lower PPPSM = 400 W | Limited to lower-energy transients; not AEC-Q101 qualified | Select when cost sensitivity outweighs automotive qualification and 600 W surge margin |
| 1.5KE30CA (Littelfuse) | Through-hole DO-201AD package; same 30 V VBR, 48.4 V VC @ 12.4 A; PPPSM = 1500 W | Requires PCB real estate and wave soldering; unsuitable for SMT-only production | Choose only if legacy through-hole design mandates compatibility or extreme single-pulse energy handling is needed |
Compared with SMAJ30CA and 1.5KE30CA, the P6SMB30CH delivers optimal balance of AEC-Q101 compliance, 600 W surface-mount surge capability, and SMB footprint - making it the preferred choice for new automotive and industrial SMT designs where reliability, density, and qualification are non-negotiable.

FAQ
What does the "CH" suffix indicate in P6SMB30CH?
The "CH" suffix denotes a bidirectional configuration - meaning the P6SMB30CH provides symmetrical transient suppression in both polarities, with identical VBR, VC, and IPPM characteristics regardless of voltage polarity applied. This eliminates the need for orientation-aware placement on PCBs and simplifies design for AC-coupled or floating signal paths.
Is P6SMB30CH suitable for automotive applications?
Yes, the P6SMB30CH is AEC-Q101 qualified and meets ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b requirements - confirming its suitability for 12 V and 24 V automotive subsystems including body control modules, lighting controllers, and infotainment power inputs. Its +150 °C TJ(max) supports under-hood deployment.
What is the clamping voltage of P6SMB30CH and why does it matter?
The P6SMB30CH has a maximum clamping voltage (VC) of 43.5 V at 14.0 A peak pulse current (10/1000 µs waveform). This value defines the highest voltage imposed on protected circuitry during a surge event - ensuring downstream components like MCUs, transceivers, or drivers remain within their absolute maximum voltage ratings and avoid latch-up or permanent damage.
How does P6SMB30CH compare to unidirectional P6SMB30H?
The P6SMB30CH is bidirectional with symmetrical electrical behavior in both directions, whereas P6SMB30H is unidirectional and requires correct anode/cathode orientation. Both share identical VBR (27.0–33.0 V), VWM (24.3 V), and PPPSM (600 W), but only P6SMB30CH supports polarity-agnostic placement - critical for differential lines or AC signals where polarity isn't fixed.
What package type does P6SMB30CH use and what are its key mechanical features?
The P6SMB30CH uses the DO-214AA (SMB) surface-mount package: 4.57 mm × 3.94 mm × 2.29 mm outline, matte tin-plated leads compliant with J-STD-002 solderability, UL 94V-0 flammability-rated molding compound, and JESD201 Class 2 whisker resistance. Its 0.090 g mass and low profile support high-speed automated assembly and thermal performance up to 150 °C junction temperature.
