Product details
Overview
P6SMB160CAH from Taiwan Semiconductor is a bidirectional 600W surface-mount Transient Voltage Suppressor (TVS) diode in DO-214AA (SMB) package, with breakdown voltage range 144–176 V, stand-off voltage 136 V, clamping voltage 219 V at 2.8 A peak pulse current, and AEC-Q101 qualification for automotive-grade surge protection.
For engineers reviewing the P6SMB160CAH datasheet, P6SMB160CAH pinout, P6SMB160CAH application, or P6SMB160CAH equivalent, this device serves as a robust, low-profile, bidirectional ESD and lightning transient protector for 12/24/48 V DC power rails, CAN/LIN bus interfaces, and automotive lighting control modules requiring ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance.
Technical Context
P6SMB160CAH is a bipolar TVS diode designed for symmetrical clamping in both forward and reverse directions, enabling protection of AC-coupled or differential signal lines without polarity sensitivity. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1 µA at 136 V), while its 10/1000 µs waveform rating supports high-energy transients up to 600 W.
The device operates across –55 °C to +150 °C junction temperature range, features 0.108 %/°C VBR temperature coefficient, and delivers fast response time (<1.0 ps from 0 V to VBR min), making it suitable for protecting sensitive analog inputs, microcontroller I/O, and power supply inputs against EFT and load dump events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 152 V / 168 V - Ensures reliable conduction onset above system nominal voltage (e.g., 136 V stand-off), minimizing false triggering during normal operation |
| VWM | 136 V - Maximum continuous reverse working voltage; defines safe operating margin before clamping begins |
| VC @ IPPM | 219 V at 2.8 A - Clamped voltage under 10/1000 µs surge; determines maximum stress imposed on downstream circuitry |
| PPPM | 600 W - Peak pulse power handling capability; supports high-energy transients per ISO 7637-2 Pulse 5a (load dump) |
| IR @ VWM | <1 µA - Ultra-low leakage preserves signal integrity and minimizes standby power loss in high-impedance circuits |
| TJ max | +150 °C - Enables use in under-hood automotive environments and thermally constrained PCB layouts |
| Package | DO-214AA (SMB) - Surface-mount footprint compatible with automated assembly; 0.090 g mass supports vibration-resistant mounting |
Pinout & Package
DO-214AA (SMB) package: molded plastic case with matte tin-plated leads, polarity indicated by cathode band (bidirectional operation means band denotes common terminal; terminals are symmetrical and non-polarized).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both terminals function identically; no polarity dependency-ideal for AC or differential line protection without orientation constraints |
| Cathode band marking | Manufacturing reference | Used for traceability only; does not define functional polarity in bidirectional configuration |
Key Features
| Feature | Design Value |
|---|---|

Applications
| Automotive Power Rail Protection | CAN Bus Transient Suppression |
|---|---|
Use Scenario: Protecting 24 V battery-fed ECUs from load dump transients (ISO 7637-2 Pulse 5a) and alternator ripple-induced spikes. IC Role / Device Role / Timing Role: Primary clamping element placed at power entry point, shunting surge energy to ground before reaching LDOs, MCUs, or gate drivers. Use Value: Limits voltage excursion to ≤219 V during 600 W surges, preventing latch-up or permanent damage to 36 V-rated input stages. |
Use Scenario: Safeguarding high-speed CAN FD transceivers (e.g., TJA1044) against ESD (IEC 61000-4-2) and coupled noise on differential bus lines. IC Role / Device Role / Timing Role: Bidirectional shunt clamp across CAN_H/CAN_L, responding within <1 ps to maintain signal integrity during ±8 kV contact discharge. Use Value: Maintains <1 µA leakage at 136 V stand-off, avoiding bus bias shift or false dominant states in low-power sleep modes. |
| LED Driver Output Protection | Industrial Sensor Signal Conditioning |
Use Scenario: Shielding constant-current LED driver outputs (e.g., in headlamp modules) from inductive kickback during PWM switching or connector hot-plug events. IC Role / Device Role / Timing Role: Parallel-connected TVS absorbing flyback energy from boost inductors or relay coils, placed adjacent to driver IC output pins. Use Value: Clamps transients to 219 V within picoseconds, preventing gate oxide rupture in external MOSFETs or internal driver FETs rated ≤250 V. |
Use Scenario: Protecting 4–20 mA loop-powered pressure/temperature sensors in factory automation against 4 kV EFT bursts and ground potential differences. IC Role / Device Role / Timing Role: Low-leakage bidirectional clamp across sensor supply and return lines, preserving milliamp-level accuracy under surge conditions. Use Value: Delivers <1 µA IR at 136 V, ensuring measurement error remains below 0.01% full scale during sustained overvoltage exposure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160CA | Same DO-214AA package, identical VBR (144–176 V), but lower PPPM (600 W same), slightly higher VC (224 V @ 2.7 A) | Marginally reduced clamping performance; may require layout review if downstream devices have ≤220 V abs max rating | Select when second-source validation is required and 5 V higher clamping voltage is acceptable in system margin analysis |
| 1.5SMC160CA | Larger DO-214AB (SMC) package, same electrical specs, higher thermal mass (RθJA = 40 °C/W vs. 55 °C/W), 1.1 g weight | Better thermal dissipation in high-ambient or high-duty-cycle surge environments; incompatible with SMB footprint | Choose for industrial power supplies where board space allows larger package and enhanced thermal resilience is prioritized over miniaturization |
Compared with SMBJ160CA and 1.5SMC160CA, P6SMB160CAH offers optimal balance of AEC-Q101 qualification, SMB footprint compatibility, and 219 V clamping-making it preferred for space-constrained automotive modules where qualification and form factor are decisive.

FAQ
What is the meaning of the 'CAH' suffix in P6SMB160CAH?
The 'CAH' suffix in P6SMB160CAH indicates a bidirectional TVS diode with AEC-Q101 qualification and halogen-free construction. 'C' denotes bidirectional configuration, 'A' specifies the tighter VBR tolerance variant (±5% vs. ±10% for 'H'), and 'H' confirms RoHS/halogen-free compliance per IEC 61249-2-21. This distinguishes it from unidirectional P6SMB160H or non-AEC-Q101 P6SMB160AH variants.
Does P6SMB160CAH meet ISO 7637-2 Pulse 5a (load dump) requirements?
P6SMB160CAH is rated for 600 W peak pulse power with a 10/1000 µs waveform, which covers ISO 7637-2 Pulse 5a up to 220 V test levels when used with appropriate series impedance. Its 219 V clamping voltage at 2.8 A ensures downstream components rated ≥250 V withstand typical load dump events without failure-verified in TSC's application notes for automotive power rail designs.
Can P6SMB160CAH be used in place of a unidirectional TVS like P6SMB160H?
No-P6SMB160CAH is strictly bidirectional and lacks polarity-dependent functionality. Substituting it for unidirectional P6SMB160H would eliminate forward-voltage blocking capability in DC applications, potentially causing reverse-bias leakage or unintended conduction. Always match configuration: use P6SMB160CAH only where symmetrical clamping (e.g., AC lines, differential buses) is required.
What is the maximum steady-state power dissipation for P6SMB160CAH at 25°C ambient?
The maximum steady-state power dissipation (Ptot) for P6SMB160CAH is 3 W at TA = 25°C, as specified in the Absolute Maximum Ratings table. This value derates linearly above 25°C per the Pulse Derating Curve (Figure 2), reaching zero at 150°C junction temperature. It is not intended for continuous power dissipation but rather for transient energy absorption.
How does the glass passivation in P6SMB160CAH improve long-term reliability?
Glass passivation in P6SMB160CAH provides superior moisture barrier and chemical resistance compared to organic passivants, reducing parameter drift over time and under humidity stress. TSC's qualification testing shows <0.5% VBR shift after 1000 hours at 85°C/85% RH-critical for automotive modules expected to operate >15 years in harsh under-hood environments.
