Product details
Overview
P6SMB130CH from Taiwan Semiconductor is a bidirectional 600W surface-mount transient voltage suppressor (TVS) diode in DO-214AA (SMB) package, with breakdown voltage 117–143 V, clamping voltage 187 V at 3.3 A peak pulse current, and AEC-Q101 qualification for automotive use. It protects power rails and signal lines against ESD, lightning surges, and inductive switching transients in 12/24 V systems.
For engineers reviewing the P6SMB130CH datasheet, P6SMB130CH pinout, P6SMB130CH application, or P6SMB130CH equivalent, key selection criteria include unidirectional vs. bidirectional configuration (CH suffix = bidirectional), clamping voltage margin relative to protected IC VDD, thermal derating above 25°C, and compliance with ISO 7637-2 Pulse 1/2a/2b/3a/3b immunity requirements.
Technical Context
The P6SMB130CH is a glass-passivated, bipolar junction TVS diode designed for fast transient suppression with sub-1 ps response time. Its bidirectional structure enables symmetrical clamping in AC-coupled or floating circuits without polarity concerns, and its 10 Ω/W junction-to-case thermal resistance supports sustained surge handling under pulsed conditions.
It operates across –55°C to +150°C junction temperature range and meets JESD201 Class 2 whisker resistance and J-STD-020 Moisture Sensitivity Level 1. Electrical behavior is defined per ANSI/IEEE C62.35, with VBR tested at 1 mA and IPPM derived from 10/1000 μs waveform.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 117 V / 143 V - ensures reliable conduction onset above system nominal voltage while avoiding false triggering during normal operation |
| VWM | 105 V - maximum continuous reverse operating voltage; must exceed peak steady-state rail voltage (e.g., 100 V max in 96 V battery systems) |
| VC @ IPPM | 187 V - clamped voltage during 3.3 A 10/1000 μs surge; defines upper voltage limit seen by downstream circuitry |
| PPPSM | 600 W - peak pulse power rating for single non-repetitive events; determines survivability against ISO 7637-2 Pulse 1 (inductive load dump) |
| IPPM | 3.3 A - peak pulse current at VC; used with PCB trace impedance to estimate actual clamping performance under real layout conditions |
| TJ max | +150 °C - maximum junction temperature; sets thermal design margin for ambient + power dissipation in high-temp environments |
| Package | DO-214AA (SMB) - industry-standard surface-mount outline with 4.5 mm × 3.9 mm footprint and 2.3 mm height; compatible with automated pick-and-place |
Pinout & Package
DO-214AA (SMB) package: molded plastic case with matte tin-plated leads, polarity indicated by cathode band (bidirectional symmetry eliminates functional polarity marking). Weight ≈ 0.090 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional transient conduction path | No functional polarity - terminals interchangeable; clamps both positive and negative transients equally |
| Case (body) | Thermal and mechanical interface | Non-electrical; provides primary heat path to PCB copper; requires adequate thermal pad area for 150°C operation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive underhood and chassis applications including engine control, body electronics, and ADAS modules |
| Glass passivated junction | Enhances long-term reliability and moisture resistance versus epoxy-passivated alternatives; critical for high-humidity environments |
| ISO 7637-2 compliance | Meets Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (capacitive coupling) test profiles |
| Low leakage & fast response | Typical IR < 1 µA above 10 V and < 1.0 ps rise time ensure minimal standby loss and effective suppression of nanosecond-scale ESD events |
| Halogen-free & RoHS | Complies with IEC 61249-2-21 and EU RoHS Directive; suitable for green manufacturing and export-controlled programs |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 24 V CAN bus power supply and microcontroller VDD inputs from load dump and alternator ripple. IC Role / Device Role / Timing Role: Bidirectional TVS clamp placed directly at connector entry point before DC/DC converter input.

IC Role / Device Role / Timing Role: Low-capacitance TVS on differential sensor lines (e.g., RS-485, 4–20 mA loop) to absorb EFT bursts and cable-coupled surges. Use Value: Maintains signal integrity by clamping transients within 1 ns while adding < 5 pF parasitic capacitance at 1 MHz. |
| LED Driver Output Protection | Power Supply Input Stage Clamping |
Use Scenario: Shielding constant-current LED driver outputs from inductive kickback when driving solenoids or relays on shared PCBs. IC Role / Device Role / Timing Role: Bidirectional TVS placed across driver output terminals to shunt flyback energy away from MOSFET drain. Use Value: Absorbs 600 W peak pulses without degradation, enabling robust operation in automotive lighting and signage systems. | Use Scenario: Front-end surge protection for industrial AC/DC power supplies subjected to mains-borne transients per IEC 61000-4-5. IC Role / Device Role / Timing Role: Primary clamping device on rectified DC bus prior to bulk capacitor and PFC stage. Use Value: Withstands 10/1000 μs surges up to 3.3 A while maintaining VC below 190 V, preserving upstream rectifier and downstream controller ratings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130CA | Same DO-214AA package, identical VBR (117–143 V), but lower PPPSM = 600 W and higher VC = 219 V at 2.7 A | Higher clamping voltage reduces margin for 130 V-rated components; less suitable for tight-voltage-margin designs | Select P6SMB130CH when lower VC (187 V) is required to protect 200 V-class FETs or capacitors |
| 1.5SMC130CA | Larger DO-214AB (SMC) package, same VBR, PPPSM = 1500 W, VC = 219 V at 6.8 A | Higher power rating suits repeated surge exposure; larger footprint limits high-density layouts | Choose P6SMB130CH for space-constrained SMB-compatible designs where 600 W suffices and lower profile is mandatory |
Compared with SMBJ130CA and 1.5SMC130CA, P6SMB130CH delivers tighter clamping (187 V vs. ≥219 V) in a low-profile SMB package-critical for protecting sensitive 150 V-rated components in automotive ECUs without increasing board area or height.

FAQ
What does the 'CH' suffix indicate in P6SMB130CH?
The 'CH' suffix in P6SMB130CH denotes a bidirectional configuration with symmetrical clamping characteristics in both polarities. Unlike unidirectional variants (e.g., P6SMB130H), the P6SMB130CH has no anode/cathode distinction and clamps transients equally on positive and negative voltage excursions-ideal for AC-coupled lines, differential buses, or floating grounds where polarity cannot be guaranteed.
How does P6SMB130CH meet ISO 7637-2 requirements?
P6SMB130CH is validated to withstand all five ISO 7637-2 test pulses: Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (capacitive coupling). Its 600 W peak pulse power rating, 187 V clamping voltage at 3.3 A, and sub-1 ps response time ensure compliance when placed at vehicle harness entry points-directly protecting ECUs from conducted transients without additional filtering.
Is P6SMB130CH suitable for 48 V automotive systems?
Yes, P6SMB130CH is appropriate for 48 V mild-hybrid and commercial vehicle systems. Its 105 V stand-off voltage exceeds typical 48 V rail peaks (≤60 V), and its 187 V clamping voltage stays well below the 200 V+ breakdown threshold of most 48 V power semiconductors. Combined with AEC-Q101 qualification and –55°C to +150°C operation, it supports under-hood deployment in next-generation architectures.
What is the thermal resistance of P6SMB130CH and how does it affect layout?
P6SMB130CH has RθJC = 10 °C/W and RθJA = 55 °C/W. To maintain TJ ≤ 150°C during repetitive surges, PCB layout must provide ≥40 mm² of 2-oz copper connected to both terminals as a thermal pad. Without this, ambient temperature rise can cause premature thermal shutdown or parametric drift-especially in enclosed enclosures or stacked boards.
Does P6SMB130CH require derating at elevated ambient temperatures?
Yes, P6SMB130CH must be derated above 25°C ambient per Figure 2 in the datasheet: power capability drops linearly to zero at 150°C. At 85°C ambient, only ~65% of rated 600 W pulse power is sustainable. Designers must verify worst-case ambient + self-heating in the final enclosure and adjust surge repetition rate or add heatsinking accordingly to avoid junction overheating.
